I grew up with CDs and never knew of one cracking. With sufficient scratching it was possibly to get them the skip, but even friends who kept CDs unboxed in piles round the CD player didn't have this problem.
Parent was talking that CDs are less tolerant of abusive handling.
There's a whole level of carelessness that never occurred to me as a teenager who grew up with CDs.
Which is/was pretty hard to do on PRESSED CD's as they were covered with a thick coating, and sometimes quite easy to do on CD-R.
> Or when you store cd's in large unboxed stacks, they can stick together, which can also damage the backside.
Also, I only ever experienced that on CD-R, never on pressed CDs.
And to be fair: If you store all your tapes unwinded on a large spool, they also might see some damage over time ;)
Both are more stable than a modern counterfeit sd card from Amazon though :P
