This is a very bad idea.
First off, you're going to have to replicate each of the lands and pits onto a new CD. Not easy.
Secondly, let's say you are trying to recover just 1MB off of a CD by recording each land and pit you see. If you record per bit, you'll be reading upwards of 8 million bits. Now, let's say you can do 2 bits a second. That would be over 46 days of solid work. No eating, drinking, or sleeping. You spend 46 solid days of your life recording each little bit off of a CD (1111 hours). Recovering a full CD (700 MB) would take over 177.5 years.
Third, data forensics of the sort already exist. As long as the cracks aren't near each other, a system could theoretically recover data from all three drives. It would be expensive and slow, but it would be possible. (NB: Another caveat of this is that all three disks must be the exact same. Literal clones of each other. No changes to any files in any way, shape, or form).
Fourth, you'll most likely be able to contact the book's publisher or just download the resources online. They're everywhere.
To answer your other question, it looks like you can see CD bumps/grooves at 1000x, so you'll probably be able to do data recovery somewhere around 1000x.
Forcing a CD to read "unrecoverable" bytes is not really possible.
The long distance between the land and a pit will be recorded as all zeros, or corrupt weird data. Not going to work.
