In addition to what the sibling says, CDDA discs have less error correction than CDROM discs. Each audio sector (frame) carries 2352 bytes of audio data, while a data sector carries just 2048 bytes of data; a different coding is used to reduce bit errors, at the expense of storage capacity.
On top of that, the audio extraction mode (in the drive) is usually optimized for constant-time delivery rather than accuracy; if an audio sector is damaged, most players will opt to deliver inaccurate data rather than stop the audio stream altogether.
- kroeckx 4y agoAn audio CD has 2352 audio bytes per sector. The sector also contains C1 error correction and C2 error detection. On a data CD, those 2352 bytes are split in 2048 data bytes, plus an additional 4 error detection, 276 error correction, plus some other bytes including an address. So there is an extra layer of error correction.
