I recently tried reading some CDs burned in 1998 or so,
on a nice SCSI Sony burner of the time, on Taiyo Yuden
media, kept in sleeves with no label or Sharpie, in a
fire-safe case (yes, I realize it wouldn't help except in
the lightest fire) in an A/C office environment. One of
five had an error. On the other hand, I probably didn't
check the original for read errors after I made it.
