CD-ROM format standards
There are three standards in the first group. The first is a proprietary standard known as the “Red Book” (formerly CD-DA), which defines those features that are common to CD-Audio and CD-ROM. It includes a measure of error correction that is adequate for audio disks. The second standard, the international standard ISO 10149, defines the additional features (including more powerful error correction) needed to allow data to be held on the disk, i.e. for recording on CD-ROM; it supersedes the proprietary “Yellow Book” standard. The third standard, ISO 9660 (developed from the earlier High Sierra standard), defines how a data file is represented on the disk in such a way that it can be accessed by different operating systems.
The second group of format standards is more diverse. An important subgroup, including DVI (digital video interactive) and CDTV, is concerned with providing TV-quality video (i.e. moving images). Because of the low data transfer rate of CD-ROM drives, this involves powerful data compression, which can also be used for still images; however, video and still bitmapped images do not normally require the additional error correction that is needed for digital data.
The CD-I format is defined by the proprietary standard known as the “Green Book”. This sets down a method of interleaving text, sound, images, and a limited form of video on the same CD-ROM disk, but is aimed at interactive domestic CD players rather than computers. The Green Book defines not only the disk format but also the hardware to support it. CD-ROM XA is a standard similar to CD-I but is aimed at personal computers.
The CD-R and CD-RW formats are regulated by the proprietary standard known as the “Orange Book”. This defines a recordable (write-once) disk that is closely compatible with CD-ROM; systems that can read CD-ROM disks can also read the CD-R format. Systems designed to read recordable disks must be multisession compatible if the disk is written in several separate sessions rather than recorded in one session (i.e. at one time, with a single table of contents); most modern systems (and all that support CD-ROM XA) comply. Photo-CD is a proprietary format for the recording of scanned color photographs on CD-R disks.
Two less frequently used format standards are CD-V, which allows a suitable player to read both CD-ROM and videodisk, and CD+G, which allows an audio CD to carry a few graphic images; both are intended for consumer products rather than computers. Other formats are likely to emerge in the future.
As the Red Book standard is common to all CD disks, most CD-ROM drives can play standard audio CD disks on which sound is recorded in the simple Red Book format and not interleaved with data or images.

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
Modern Language Association
The Chicago Manual of Style

- Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
- In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
