Out of Balance CD+G Disks

[jim in ohio]

Bernie,
Yes I have had some vibration from some of my discs reading at 40X, I have found that cleaning my discs first helps some.
We use contract Kjocks, and have found that Pizza and wing sauce does make the old discs shake when spinning that fast.
For most backups I just use a clean tshirt washed without fabric softner, use my breath to make a damp section on the disc then wipe from the center out. Five or six sections to clean most discs, have had to use plain water for some really stickie sauce.
I get better backups using cleaned discs, and better backups at the higher read speeds.
