(when it says 52x on some drives it does mean 52 times a second which is a considerable thing to have off balance in a drive, possibly even your expensive litescribe drive).
It is not that easy – and potentially even faster rotation.
The speed 1x, 2x,... 72x isn't directly rotations per second, but depends on the position of reading. Fast optical drives (all drives since way more than 20 years) read an undamaged optical disc with constant angular velocity (CAV, rotating with constant speed, reading faster when going to the outer part of the disc) rather than constant linear velocity (CLV, rotating slower when going to the outer part of the disc, reading at constant speed). Speed above about 20 times faster than playing an audio CD (80 min at 1x) can't be reached on the most inner part of the disc by a conventional drive.

Ironically the few drives (or was it just one model?) going beyond the usual maximum of 48x, 52x or 56x at best, spin the disc slower reaching 72x with multiple lasers.

Having a damaged and/or unbalanced CD is a big problem regardless of the actual numbers. I wouldn't recommend labels/stickers.

Don't have a source at hand: I believe to remember having read the following two statements: An undamaged, good CD can explode when using more than 10000 RPM (or was it 15000?). DVDs are a bit more sturdy.
Even taking those limits in account and drives staying below that value, unbalance and/or damage can make an optical disc literally explode into pieces.

This picture from https://en.wikipedia.org/wiki/Optical_disc_drive always made me nervous when inserting a Wii game from the public library with their big labels. Luckily the Wii doesn't go to insane rotation speed (already loud enough).
