Optical Disc FormatsOptical drives can use many types of disc formats and standards. This section discusses the formats and file systems used by optical drives, so you can make sure you can use media recorded in a particular format with your drive. CD FormatsAfter Philips and Sony created the Red Book CD-DA format discussed earlier in the chapter, they began work on other format standards that would allow CDs to store computer files, data, and even video and photos. These standards control how the data is formatted so that the drive can read it, and additional file format standards can then control how the software and drivers on your PC can be designed to understand and interpret the data properly. Note that the physical format and storage of data on the disc as defined in the Red Book was adopted by all subsequent CD standards. This refers to the encoding and basic levels of error correction provided by CD-DA discs. The other 'books' specify primarily how the 2,352 bytes in each sector are to be handled, what type of data can be stored, how it should be formatted, and more.All the official CD standard books and related documents can be purchased from Philips for $100—$150 each.

See the Philips licensing site at for more information.Table 11.18 describes the various standard CD formats, which are discussed in more detail in the following sections. Compact Disc FormatsFormatNameIntroducedNotesRed BookCD-DA (compact disc digital audio)1980—by Philips and Sony.

Specifies an interactive audio/video standard for non-PC-dedicated player. NOTEWindows XP also has limited CD-RW support in the form of something called IMAPI (image mastering application program interface), which enables data to be temporarily stored on the hard drive (staged) before being written to the CD in one session.

Additional sessions can be written to the same disc, but a 50MB overhead exists for each session. This gives some of the appearance of packet writing, but it is not really the same thing. To read packet-written discs in the UDF 1.5 or later format, you must install a UDF reader just as with previous versions of Windows. Instead of using IMAPI, I recommend installing a third-party CD-mastering program that also includes packet-writing UDF support, such as Roxio Creator 2011 or Nero.When you remove a packet-written disc from the drive, the packet-writing software first asks whether you want the files to be visible in all drives. If you do, you must close the session. Even if the session is closed, you can still write more to the disc later, but there is an overhead of wasted space every time you close a session.

If you are going to read the disc in a rewritable drive, you don't have to close the session because it will be capable of reading the files even if the session isn't closed. CAUTIONIf you are not sure what type of drive will be used to read the media, I recommend closing the media. This enables users of various types of drives to read the media, although a compatible UDF reader program must be installed in some cases.A newer standard called Mount Rainier (Mt. Rainier) adds even more capability to packet writing. With Mount Rainier, packet writing can become an official part of the operating system (OS) and the drives can support the defect management necessary to make them usable as removable storage in the real world. For more information, see the section 'Mount Rainier' later in this chapter. NOTEAs part of Service Pack 1, Microsoft released updates for Windows XP that add native support for the Mount Rainier standard, which supports full drag-and-drop packet writing through CD-MRW drives as well as DVD+MRW drives.

Microsoft Windows 7 and Vista include native support of Mount Rainier. Photo CDFirst announced back in 1990 but not available until 1992, Photo CD was a standard that used CD-R discs and drives to store photos. Although Kodak originally sold Photo CD 'players' that were connected to TVs, most Photo CD users used computer-based optical drives along with software to decode and display the photos.Perhaps the main benefit Photo CD brought to the table is that it was the first CD format to use the Orange Book Part II (CD-R) specification with multisession recordings.

Additionally, the data is recorded in CD-ROM XA Mode 2, Form 2 sectors; therefore, more photo information could be stored on the disc.Kodak's own PhotoYCC encoding format was used to store up to six resolutions for each image, as shown in Table 11.20. The x64 resolution was supported only by the Pro Photo CD master version of the service.

However, with the rise of high-speed PCs running Adobe Photoshop, Adobe Photoshop Elements, and other photo-editing programs, along with high-speed, low-cost recordable and rewritable optical drives, the Photo CD format became obsolete.

Kodak discontinued development in the early twenty-first century, and third-party labs that offered the service discontinued it in 2004. Kodak still offers drivers, software, and firmware for Pro Photo CD at. Picture CDAs a replacement for Photo CD, Kodak now offers the simpler Picture CD service.

Unlike Photo CD, Picture CD uses the industry-standard JPEG file format. It uses a CD-R, with up to 40 images stored at a single medium-resolution scan of 1,024x1,536 pixels. This resolution is adequate for 4-inchx6-inch and 5-inchx7-inch prints. The images can also be made available via Kodak Gallery, where the same images are posted online and can be downloaded.The software provided with Picture CD enables the user to manipulate images with various automatic or semiautomatic operations, but unlike Photo CD, the standard JPEG (JPG) file format used for storage enables any popular image-editing program to work with the images without conversion. Services similar to Picture CD are also offered by Fujifilm and Agfa, and some stores allow you to order Kodak Picture CD with your choice of store-brand or Kodak film processing. You can also create a Picture CD at kiosks that include a Rapid Print Scanner. NOTEBy scanning your own 35mm negatives with a high-performance flatbed or dedicated film scanner, you can achieve much higher resolutions (up to 4,800 dpi optical) that support larger images sizes than what Picture CD offers.

This thing is like a demo software. Not much in it. So it installs on another directory. I guess they just want to show they are developing Car Brain II.Per my opinion, it's worthless trying to look into this. Carbrain c168 software update download.

For example, a 3,200 dpi scan of a full-frame 35mm film negative has a resolution of about 2,570x4,450 pixels. By scanning negatives yourself, you can also select the quality of JPEG images and save images in other formats, such as TIFF.

Some photo labs offer high-resolution film developing and scanning services if you prefer not to scan your own film. White Book—Video CDThe White Book standard was introduced in 1993 by Philips, JVC, Matsushita, and Sony. It is based on the Green Book (CD-i) and CD-ROM XA standards and allows for storing up to 74 minutes of MPEG-1 video and ADPCM digital audio data on a single disc. The latest version (2.0) was released in April 1995.

Video CD (VCD) 2.0 supports MPEG-1 compression with a 1.15Mbps bit rate. The screen resolution is 352x240 for NTSC format and 352x288 for European PAL format. In addition, it supports Dolby Pro Logic–compatible stereo sound.You can think of VCDs as a sort of poor man's DVD format, although the picture and sound quality can actually be quite good—certainly better than VHS or most other videotape formats. You can play VCDs on virtually any PC with an optical drive using the free WMP. (Other media player applications can be used as well.) You can also play VCDs on most DVD players. Although you can create VCDs with popular DVD production programs such as Roxio Creation 2011 or Adobe Premiere Elements, prerecorded VCD media is difficult to find today, thanks to the popularity of the higher-quality (and easier to copy-protect) DVD and Blu-ray formats. Super Video CDThe Super Video CD specification 1.0, published in May 1999, is an enhanced version of the White Book VCD specification.

It uses MPEG-2 compression, an NTSC screen resolution of 480x480, and a PAL screen resolution of 480x576; it also supports MPEG-2 5.1 surround sound and multiple languages.Most home DVD-creation programs can create VCDs or Super VCDs. Blue Book—CD EXTRAManufacturers of CD-DA media were looking for a standard method to combine both music and data on a single CD. The intention was for a user to be able to play only the audio tracks in a standard audio CD player while remaining unaware of the data track.

However, a user with a PC or dedicated combination audio/data player could access both the audio and data tracks on the same disc.The fundamental problem with nonstandard mixed-mode CDs is that if or when an audio player tries to play the data track, the result is static that could conceivably damage speakers and possibly hearing if the volume level has been turned up. Various manufacturers originally addressed this problem in different ways, resulting in a number of confusing methods for creating these types of discs, some of which still allowed the data tracks to be accidentally 'played' on an audio player. In 1995, Philips and Sony developed the CD EXTRA specification, as defined in the Blue Book standard. CDs conforming to this specification usually are referred to as CD EXTRA (formerly called CD Plus or CD Enhanced Music) discs and use the multisession technology defined in the CD-ROM XA standard to separate the audio and data tracks.

These are a form of stamped multisession disc. The audio portion of the disc can consist of up to 98 standard Red Book audio tracks, whereas the data track typically is composed of XA Mode 2 sectors and can contain video, song lyrics, still images, or other multimedia content. Such discs can be identified by the CD EXTRA logo, which is the standard CD-DA logo with a plus sign to the right. Often the logo or markings on the disc package are overlooked or somewhat obscure, and you might not know that an audio CD contains this extra data until you play it in a computer-based optical drive.A CD EXTRA disc normally contains two sessions. Because audio CD players are only single-session capable, they play only the audio session and ignore the additional session containing the data. An optical drive in a PC, however, can see both sessions on the disc and access both the audio and data tracks.

Scarlet Book (SA-CD)The Scarlet Book defines the official standard for Super Audio CD (SA-CD, also referred to as SACD) media and drives. It was codeveloped by Philips Electronics and Sony in 1999. Unlike the original Red Book CD-Audio standard, which samples music at 44.1KHz, Scarlet Book uses Direct Stream Digital encoding with a sampling rate of 2.822MHz—64 times the sampling frequency of Red Book.Because of the higher sampling rate and the larger disc capacity necessary to store the audio (as well as SA-CD's support for video and text content), you cannot play standard or dual-layer SA-CD media in a standard CD player or computer's CD or DVD drive. Although standard SA-CD media has a capacity of 4.7GiB (the same as that of single-layer DVD), the formats are not interchangeable.

SA-CD contents are copy-protected by a physical watermark known as Pit Signal Processing, which cannot be detected by standard computer DVD drives, although some high-end BD and DVD set-top boxes can also play SA-CD media.Almost all SA-CD albums use a hybrid dual-layer design, in which the top layer stores standard CD audio playable on standard CD players and drives, and the lower layer contains the higher-density SA-CD content. Essentially, a hybrid SA-CD disc is like a CD-audio disc and a standard SA-CD disc in a single-sided disc (see ).

NOTEAlthough you can play hybrid SA-CD media in standard players or computer-based drives, these devices are only playing the CD layer. To enjoy the enhanced audio of SA-CD, you must use a standalone SA-CD player.An SA-CD disc (or the SA-CD layer of a hybrid disc) includes the stereo version of the album in its inner portion, a six-channel surround audio mix in the middle portion, and extra data such as lyrics, graphics, and video in the outer portion.For listings of SA-CD albums and players and additional SA-CD information, see. DualDiscDualDisc, introduced by a consortium of major record labels in the summer of 2004 is a combination of two different formats—music CD and DVD—on a single two-sided disc.

DualDisc (sometimes referred to as Dual Disc), as the name suggests, is two discs in one: One side is a music CD, typically featuring support for surround audio or other advanced audio formats, and the other side is a DVD (using the single-layer DVD-5 format) that can include music videos, concert footage, web links, and other features.Although DualDisc is designed to work in standard CD drives and players, it is not completely compatible with Red Book standards because the CD layer is only 0.9mm, compared to the Red Book standard of 1.1mm. To compensate for spherical aberration caused by a thinner CD layer, one method used is to increase the size of the pits on the CD side of a DualDisc, reducing playing time to 60 minutes. (Some later DualDisc media uses different methods to increase playtime.)The total thickness of a DualDisc is 1.5mm, compared to 1.2mm for standard CD or DVD media, causing DualDiscs to be incompatible with slot-loading drives in car stereos, PCs, and mega-disc changers. Because DualDisc media is thicker than normal CD media and because the internal structure of the CD side is not compatible with Red Book standards, Philips and Sony (the co-creators of the CD format) do not use the CD logo on DualDisc media, and most DualDisc albums include warning labels that the disc will not work in slot-loaded drives and mega-disc changers and might not play in other types of players. DualDisc albums are typically packaged in CD-style jewel cases.

CAUTIONSome music vendors use the term DualDisc to refer to SA-CD as well as actual DualDisc albums. Be sure to check details of the media carefully to ensure that you can play the disc in your equipment.Although DualDisc media, unlike SA-CD media, supports two standard formats, it is not nearly as popular as SA-CD media. Thousands of albums are available in SA-CD format, but only a few hundred are available in DualDisc format (virtually none after 2006). SA-CD provides far better audio quality than DualDisc (which provides only CD quality music), making it a better format for the serious audiophile. DVD Formats and StandardsAs with the CD standards, the DVD standards are published in reference books produced mainly by the DVD Forum, but also by other companies, such as the DVD+RW Alliance. The DVD Forum's DVD-Video and DVD-ROM standards are well established and are supported by virtually every DVD drive, regardless of age.

However, rival recordable and rewritable DVD standards have been developed by both organizations. NOTEThe Mac HFS and UNIX Rock Ridge file systems are not supported by PC OSs such as DOS and Windows and therefore are not covered in depth here.

High SierraTo make optical discs readable on all systems without having to develop custom file systems and drivers, it was in the best interests of all PC hardware and software manufacturers to resolve the optical file format standardization issue. In 1985, representatives from TMS, DEC, Microsoft, Hitachi, LaserData, Sony, Apple, Philips, 3M, Video Tools, Reference Technology, and Xebec met at what was then called the High Sierra Hotel and Casino in Lake Tahoe, Nevada, to create a common logical format and file structure for CD-ROMs. In 1986, they jointly published this standard as the 'Working Paper for Information Processing: Volume and File Structure of CD-ROM Optical Discs for Information Exchange (1986).' This standard was subsequently referred to as the High Sierra format.This agreement enabled all drives using the appropriate driver (such as MSCDEX.EXE supplied by Microsoft with DOS) to read all High Sierra format discs, opening the way for the mass production and acceptance of CD-ROM software publishing. Adoption of this standard also enabled disc publishers to provide cross-platform support for their software and easily manufacture discs for DOS, UNIX, and other OS formats.

Without this agreement, the maturation of the optical marketplace would have taken years longer and the production of optical-based information would have been stifled.The High Sierra format was submitted to the International Organization for Standardization (ISO). Two years later (in 1988), with several enhancements and changes, it was republished as the ISO 9660 standard. ISO 9660 was not exactly the same as High Sierra, but all drivers that would read High Sierra–formatted discs were quickly updated to handle both ISO 9660 and the original High Sierra format on which it was based.For example, Microsoft wrote the MSCDEX.EXE (Microsoft CD-ROM extensions) driver in 1988 and licensed it to optical hardware and software vendors to include with their products. It wasn't until 1993 when MS-DOS 6.0 was released that MSCDEX was included with DOS as a standard feature.

MSCDEX enables DOS to read ISO 9660–formatted (and High Sierra–formatted) discs. This driver works with the AT Attachment Packet Interface (ATAPI) or Advanced SCSI Programming Interface (ASPI) hardware-level device driver that comes with the drive. Microsoft built ISO 9660 and Joliet file system support directly into Windows 95 and later, with no additional drivers necessary. ISO 9660The ISO 9660 standard enabled full cross-compatibility among different computer and operating systems.

ISO 9660 was released in 1988 and was based on the work done by the High Sierra group. Although based on High Sierra, ISO 9660 does have some differences and refinements. It has three levels of interchange that dictate the features that can be used to ensure compatibility with different systems.ISO 9660 Level 1 is the lowest common denominator of all CD file systems and is capable of being read by almost every computer platform, including UNIX and Macintosh. The downside of this file system is that it is very limited with respect to filenames and directories. Level 1 interchange restrictions include the following:. Only uppercase characters A–Z, numbers 0–9, and the underscore are allowed in filenames.

Only 8.3 characters maximum for the name.extension (based on DOS limits). Directory names are eight characters maximum (no extension allowed). Directories are limited to eight levels deep. Files must be contiguous.Level 2 interchange rules have the same limitations as Level 1, except that the filename and extension can be up to 30 characters long (both added together, not including the.

Finally, Level 3 interchange rules are the same as Level 2 except that files don't have to be contiguous.Note that Windows 95 and later versions enable you to use file and folder names up to 255 characters long, which can include spaces as well as lowercase and many other characters not allowed in ISO 9660. To maintain backward compatibility with DOS, Windows 95 and later associate a short 8.3 format filename as an alias for each file that has a longer name. These alias short names are created automatically by Windows and can be viewed in the Properties for each file or by using the DIR command at a command prompt. To create these alias names, Windows truncates the name to six (or fewer) characters followed by a tilde and a number starting with 1 and truncates the extension to three characters. Other numbers are used in the first part if other files that would have the same alias when truncated already exist. For example, the filename This is a.test gets THISIS1.TES as an alias.This filename alias creation is independent of your CD drive, but it is important to know that if you create or write to a CD using the ISO 9660 format using Level 1 restrictions, the alias short names are used when files are recorded to the disc, meaning any long filenames will be lost in the process.

In fact, even the alias short name will be modified because ISO 9660 Level 1 restrictions don't allow a tilde—that character is converted to an underscore in the names written to the CD.The ISO 9660 data starts at 2 seconds and 16 sectors into the disc, which is also known as logical sector 16 of track one. For a multisession disc, the ISO 9660 data is present in the first data track of each session. This data identifies the location of the volume area—where the actual data is stored. The system area also lists the directories in this volume as the volume table of contents (VTOC), with pointers or addresses to various named areas, as illustrated in.

A significant difference between the CD directory structure and that of a normal hard disk is that the CD's system area also contains direct addresses of the files within the subdirectories, allowing the CD to seek specific sector locations on the spiral data track. Because the CD data is all on one long spiral track, when speaking of tracks in the context of a CD, we're actually talking about sectors or segments of data along that spiral. A diagram of basic ISO 9660 file organizational format.To put the ISO 9660 format in perspective, the disc layout is roughly analogous to that of a floppy disk. A floppy disk has a system track that not only identifies itself as a floppy disk and reveals its density and OS, but tells the computer how it's organized (into directories, which are made up of files). JolietJoliet is an extension of the ISO 9660 standard that Microsoft developed for use with Windows 95 and later.

Joliet enables CDs to be recorded using filenames up to 64 characters long, including spaces and other characters from the Unicode international character set. Joliet also preserves an 8.3 alias for those programs that can't use the longer filenames.In general, Joliet features the following specifications:. File or directory names can be up to 64 Unicode characters (128 bytes) in length. Directory names can have extensions. Directories can be deeper than eight levels. Multisession recording is inherently supported.

TIPBecause Joliet supports a shorter path than Windows 9x and newer versions, you might have difficulties mastering a Joliet-format CD that contains extremely long pathnames. I recommend you shorten folder names in the file structure you create with the CD mastering software to avoid problems. Unfortunately, some CD mastering programs don't warn you about a pathname that is too long until after the burning process starts.

If your CD mastering program offers an option to validate your disc structure, use this option to determine whether you need to shorten folder names. Some CD mastering programs will provide a suggested short name and shorten too-long folder names for you.Due to backward-compatibility provisions, systems that don't support the Joliet extensions (such as older DOS systems) should still be capable of reading the disc.

However, it will be interpreted as an ISO 9660 format using the short names instead. NOTEA bit of trivia: 'Chicago' was the code name used by Microsoft for Windows 95. Joliet is the town outside of Chicago where Jake was locked up in the movie The Blues Brothers. Universal Disk FormatUDF is a file system created by the Optical Storage Technology Association (OSTA) as an industry-standard format for use on optical media, but it can also be used by other types of removable-media drives, such as the Iomega REV drives. UDF has several advantages over the older ISO 9660 file system but is most noted because it is designed to work with packet writing, a technique for writing small amounts of data to an optical disc, treating it much like a standard magnetic drive. The UDF file system allows long filenames up to 255 characters per name. There have been several versions of UDF, with most packet-writing software using UDF 1.5 or later.

Packet-writing software such as Roxio's DirectCD and Drag-to-Disc, Ahead Software's InCD, and Veritas and Sonic Solutions' DLA use the UDF file system. However, standard optical drives, drivers, and OSs such as DOS can't read UDF-formatted discs. Recordable drives can read them, but regular optical drives must conform to the MultiRead specification (see the section 'MultiRead Specifications,' earlier in this chapter) to be capable of reading UDF discs.After you are sure that your drive can read UDF, you must check the OS. Most OSs can't read UDF natively—the support has to be added via a driver. DOS can't read UDF at all; however, with Windows 95 and later, UDF-formatted discs can be read by installing a UDF driver. Typically, such a driver is included with the software that comes with most CD-RW and rewritable DVD drives.If you don't have a UDF reader, you can download one from the following websites:. Get UDF Reader 2.5 for Windows XP from.

Get UDF Volume Reader 7.1.0.95 for Windows 9x through XP from. Get Nero AG Software's InCD Reader from the support section of.After the UDF driver is installed, you do not need to take any special steps to read a UDF-formatted disc. The driver will be in the background waiting for you to insert a UDF-formatted disc.If you are unable to read a disc written with UDF on another system, return it to the original system and close the media. This option is usually displayed as part of the Eject Settings dialog box. Closing the disc converts the filenames to Joliet format and causes them to be truncated to 64 characters.You can download the latest (revision 2.60) version of the Universal Disk Format specification from the OSTA website at. TIPUDF discs can become unreadable for a variety of reasons, including incompatible UDF reader installed, disc not closed before removal of drive, table of contents not written due to system lockup, and so on. To recover data from UDF discs, try CD Roller (available from ).

Convert Udf To Dvd Format

It supports the most commonly used UDF versions (v1.02 through 2.01, and UDF Bridge) and also works with optical discs created by digital cameras, DVD recorders, and DVD-based camcorders. Another optical disc recovery program to consider is IsoBuster. IsoBuster also works with BD formats. Macintosh HFSHFS is the file system used by the Macintosh OS. HFS can also be used on optical discs; however, if that is done, they will not be readable on a PC.

A hybrid disc can be produced with both Joliet and HFS or ISO 9660 and HFS file systems, and the disc would then be readable on both PCs and Macs. In that case, the system will see only the disc that is compatible, which is ISO 9660 or Joliet in the case of PCs. Rock RidgeThe Rock Ridge Interchange Protocol (RRIP) was developed by an industry consortium called the Rock Ridge Group. It was officially released in 1994 by the IEEE CD-ROM File System Format Working Group and specifies an extension to the ISO 9660 standard for CD-ROM that enables the recording of additional information to support UNIX/POSIX file system features. Neither DOS nor Windows includes support for the Rock Ridge extensions.

However, because it is based on ISO 9660, the files are still readable on a PC and the RRIP extensions are simply ignored.

I am trying to move files from a backup DVD and CD (that was created using Windows XP and Nero) to my new PC running Windows 7 with Roxio. When I open the discs with explorer, windows tells me that the files are empty (and I know the data is there).I think the problem has something to do with the UDF format used to close the discs. The old PC is gone, so I can't use easy transfer. Is there asafe UDF reader out there that works with Windows 7 64bit?Thanks for any help you can provide.Joe.
