Hi, Actually, the process is referred to as "eight to fourteen modulation" (EFM) in which 8-bit words are recorded as 14 bit words with no less than 3 and no more than 11 consecutive "1"s or "0"s. This means that there is a fixed ratio between the incoming and the outgoing bit rate so this process is of no influence to the stability of the clock (which would be the only way to influence the sound quality). For more on clock stability, read my reply to question no. 976251114.Eg The EFM scheme was invented to make use of the property that pit length differences can be read to much shorter lengths than the shortest pit, packing more data per area without any loss of data reliability.
