HistoryĮarly Apple CD-ROM mechanisms used SCSI connectors, typically set to ID #3. The standard was later amended to allow variances of up to 700 MB (79.8 minutes), though some drives have allowed for usable capacities as high as 750 MB (85 minutes). The original standard specified that each disc could contain up to 99 tracks and store 650 MB (74 minutes). Audio was encoded in 16-bit resolution at 44.1 kHz. 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.
