In Reply to: RE: Absolute level of CD during play posted by tomservo on September 10, 2023 at 07:26:26:
Buffers would not solve the problem of data corruption since the data corruption occurs while the laser is reading the pits and lands on the CD. The buffers would therefore contain the corrupted data. The reason why portable players use buffers is to prevent skipping due to the shock produced by walking. E.g., Sony Walkman.What CD players/transports do have to address the issue of data corruption are laser servo feedback system and Reed Solomon error detection and correction codes. But neither of those implementations are perfect, so data isn't perfect going forward from the laser reading process. And that's why the various CD and CD player tweaks are audible. Vibration isolation, scattered laser light absorption, CD stabilization and CD level.
