CD-ROM (an acronym for Compact Disc Read-Only Memory) is an optical media format that was popular in the 1990s. It was superseded by the DVD-ROM format.

SpecificationsEdit

The Red Book standard for compact discs specified a bit rate of 153,600 bytes (150 KB) per second, referred to as "1x" CD-ROM speed. Audio was encoded in 16-bit resolution at 44.1 kHz. The original standard specified that each disc could contain up to 99 tracks and store 650 MB (74 minutes).[1] The standard was later amended to allow variances of up to 700 MB (79.8 minutes),[2] though some drives have allowed for usable capacities as high as 750 MB (85 minutes).[3]

HistoryEdit

The first Adobe product to be available on CD-ROM was the deluxe edition of Adobe Photoshop 2.5, released in November 1992.[4] By version 4, released in 1996, a CD-ROM drive was required and floppy disks were only available upon request.[5] Adobe Creative Suite 2 was the last software suite from Adobe to be shipped on CD-ROM. Creative Suite 3 was released on DVD-ROM in April 2007. [6][7]
