Well,
This makes me want to go out and test my drives, I have been slack! I have 2 LTR40125s (a long story), an LTD163 and a Ricoh MP7120a. I also have access to another LTR40125S (quality control tests?) and an LTD163D. The interesting thing is that my testing on real damaged CDs has shown that the MP7120A beats the tar out of both the 40125s and LTD163 as an audio ripper.
My LTD163 does not handle concentric stratches at all well (even light ones) whereas the Ricoh doesn't even notice they are there. Also, where CDs have damage to he reflective layer, the Ricoh can still recover more (seemingly) correct information than either of the Liteons, perhaps an indicator to superior CIRC. One thing, the Ricoh rips better fast than slow, I assume the optics and servos are 'tuned' for the higher speeds.
I may get a chance to post some interesting results I have. I have found another one of those strange CDs with repeatable errors - they ar always entertaining.
Regards,
Bob
