My undestanding was that muting always leading to a null sample
|
No, in fact usually the drives repeat the last valid sample (otherwise there would be always a click, as there would be a change of sound pressure)...
When valid samples occur afterwards, usually a linear interpolation is done from that sample to the valid sample...
Scratches and other errors are usually optical problems (not artificial CIRC errors like copy protections). It is very easy that the optics read one time a '1' and the other time a '0' on a very defective part. It is then the error correction doint something from there...

This way, is the secure mode more secure than the paranoid mode ?
|
Yes and no. It works better for also recovering errors 1-2 blocks before the actual error, but this is usually also done in the paranoid mode. So both nearly have the same probability to find errors (as the events are independent)...
