There are quite a few "substandard discs" floating around, unfortunately. Toshiba was talking about the many CD discs that are manufactured poorly. They wobble during playback because they are slightly out of round and slightly out of balance.The old AudioDesk CD edge cutting system was designed as a remedy to the problem of poorly manufactured, out-of-round, unbalanced discs.

Yes I realize that but in this case the dampers were too soft and eventually over time they completely collapse and the disc will not spin nor can it easily be removed. It is possible that Toshiba thought the problem was due to wobbly (unbalanced) disc at the time though.
Interesting. Can you describe the faulty Toshiba dampers (thickness, material, etc...)?
They are rubber dampers and look like big thick gromets. The replacements were Toshiba part #79070496. They are no longer available. You can see them in the Toshiba SD-5700 mechanism above (2 blue & 2 black). I believe the originals were 2 grey and 2 green.
I can't understand why the original grommets would have failed so quickly. Strange.
Do the blue grommets have a different stiffness or durometer rating than the black ones?
Well I should say mine didn't fail but there are post of the original ones failing over time.
Yes all the different colors have a different stiffness. The original ones didn't actually fail (at least to my knowledge) they just weren't right for the application.
