I would assume it uses different error correction- CIRC
The smallest entity in a CD is called a channel-data frame, which consists of 33 bytes and contains six complete 16-bit stereo samples (two bytes × two channels × six samples = 24 bytes). The other nine bytes consist of eight CIRC error-correction bytes and one subcode byte, used for control and display. Each byte is translated into a 14-bit word using eight-to-fourteen modulation, which alternates with three-bit merging words. In total there are 33 × (14 + 3) = 561 bits. A 27-bit unique synchronization word is added, so that the number of bits in a frame totals 588 (which are decoded to only 192 bits music (the 24 bytes mentioned above)).
These 588-bit channel-data frames are in turn grouped into a larger structure, confusingly dubbed frame in the Red Book audio CD's timecode-based addressing system. In CD-ROM and related technology, including Digital Audio Extraction (DAE, or ripping of audio CDs), the same structure is called a sector and is addressed with simple, sequential, non-negative integer numbers. Regardless of which name is used, each of these structures contains 98 channel-data frames, totaling 98 × 24 = 2352 bytes of music. The CD is played at a speed of 75 frames (or sectors) per second, which results in 176,400 bytes per second. Divided by two channels and two bytes per sample, this results in a sample rate of 44,100 samples per second.
Good sound—like good music, good wine and good fellowship—is meant to be shared.
