Diverse Disc Formats
Ken C. Pohlmann · 1992
Abstract The versatility of the compact disc has quickly become apparent to manufacturers and users alike. Since music is an extremely storage-hungry phenomenon, the CD must have a tremendous storage capacity. To take further advantage of that capacity, other CD formats have been devised. CD-ROM was developed, incorporating nonaudio data, such as data base and software data. CD-I and DVI are specific applications of CD-ROM. Their data storage opportunities include audio-visual information stored in a user-interactive manner. CD-V merges the compact disc audio format with the Laservision video format. CD-R is a write-once format allowing users to store their own data. In addition, recordable/erasable CD formats have been developed as well as incompatible formats such as the Mini Disc. CD + G/M features storage for graphics and other nonmusical data. A smaller diameter compact disc, the CD-3 is used for applications requiring shorter playing time.
