Optical Disc Formats

Optical 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 Formats

After 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 www.ip.philips.com for more information.

Table 11.18 describes the various standard CD formats, which are discussed in more detail in the following sections.
