This sounds as though you're talking about CDDA.

CDs have, effectively, a physical sector size of 2352 bytes (44100
samples/sec * 2 channels * 2 bytes/sample/channel / 75 frames/sec).  (I
believe the physical sector is a little larger because of stuff like
the subchannel info, but it's 2352 data bytes.)  For data tracks, 304
bytes are used for ECC bits, for an effective data sector size of 2048
bytes - but for digital audio, all 2352 bytes are audio data.

If you have a drive that can rip audio tracks, it can be put into a
2352-byte-sector mode....
