However, given that the break won't be perfectly straight and will tend to
align itself, I wouldn't be surprised if a join to close tolerances wasn't
that hard, with the right equipment.  You'd want to spin a patched-together
disk slowly, mind you.

Given how much error correction is built into the format, I suspect there
wouldn't be that much trouble doing an acceptable recovery, if the
alignment was close enough that the head servo could maintain track
following across the break. 

(Still, I agree with the general conclusion that unless he's really nuts
about this particular music, recovery is probably too expensive...)
