so then get a Panasonic JU-475-4 or -5 drive and file away the
mechanical stop a little bit. The rails and other mechanical parts are
long enough to allow the head to step back to track -4 (ca. 2.15mm).

Perhaps you need to modify the optical track 1 sensor a bit, so that it
is also close for track -3 and -4, but that's it.


Somtimes in the future I will check some other potential drive type
candidates for such a modification since I'm not (yet?) much impressed
from the Panasonic's read-back capabilities with "difficult" disks.
