Capacity of a CD-ROM
The capacity of a CD-ROM depends on whether it is a Mode 1 CD-ROM or Mode 2 CD-ROM XA. Assuming the maximum size is 76 minutes 30 seconds (as recommended) this means that there are 336,300 sectors on a CD-ROM. From this must be subtracted 166 sectors at the start of track 1 plus a few sectors for the file system, amounting to, say, 200 sectors leaving 336,100 sectors for user data.
Mode 1 sectors contain 2048 bytes per sector giving a total capacity of 688,332,800 bytes or 656MB.
Mode 2 sectors contain either 2048 or 2324 bytes per sector so will have a somewhat higher data capacity depending on the mix of the two types of sector.
The above assumes a CD-ROM comprising a single track in a single session. For multiple track/session discs the data capacity will be reduced.
CD Audio Parameters:
Compact Discs have the following parameters for audio stored on them:
Sample rate: 44.1 kHz
Channels: 2 (stereo)
Bits per sample, per channel: 16
Levels per sample: 65,536
Total data rate (Mb/s): 1.4112
