The Yellow Book was written in 1984 to describe the extension of CD to store computer data, i.e. CD-ROM (Read Only Memory). This specification comprises the following:
- Disc specification which is a copy of part of the Red Book
- Optical stylus parameters (from Red Book)
- Modulation and error correction (from Red Book)
- Control & display system (from Red Book)
- Digital data structure, which describes the sector structure and the ECC and EDC for a CD-ROM disc.
