The CD-ROM was later designed as an extension of the CD-DA, and adapted this format to hold any form of digital data, with an initial storage capacity of 553 MB. [5] Sony and Philips created the technical standard that defines the format of a CD-ROM in 1983, [ 6 ] in what came to be called the Yellow Book .
For the first few years of its existence, the CD was a medium used purely for audio. In 1988, the Yellow Book CD-ROM standard was established by Sony and Philips, which defined a non-volatile optical data computer data storage medium using the same physical format as audio compact discs, readable by a computer with a CD-ROM drive.
The 120 mm (5") disc has a storage capacity of 74 minutes of audio or 650 Megabytes (MBs) of data. CD-R/RWs are available with capacities of 80 minutes of audio or 737,280,000 bytes (700 MB), which they achieve by molding the disc at the tightest allowable tolerances specified in the Orange Book CD-R/CD-RW standards.

As of 2007 DVD is the de facto standard for pre-recorded movies, and popular storage of data beyond the capacity of CD. With the development of high-definition television , and the popularization of broadband and digital storage of movies, a further format development took place, again giving rise to two camps: HD DVD and Blu-ray , based upon a ...
The chief advantages of the CD-ROM format were (1) larger storage capacity, allowing for a much greater amount of game content; [6] [7] (2) considerably lower manufacturing costs, making them much less risky for game publishers; [7] [8] (3) lower retail prices due to the reduced need to compensate for manufacturing costs; [6] [7] [9] and (4 ...
A core feature of the Sega CD is the increase in data storage by its games being CD-ROMs; whereas ROM cartridges of the day typically contained 8 to 16 megabits of data, a CD-ROM disc can hold more than 640 megabytes of data, more than 320 times the storage of a Genesis cartridge. This increase in storage allows the Sega CD to play FMV games. [6]
In the history of optical storage media there have been and there are different optical disc formats with different data writing/reading speeds.. Original CD-ROM drives could read data at about 150 kB/s, 1× constant angular velocity (CAV), [1] the same speed of compact disc players without buffering.
