The alignment definitely seems to have slipped. I can format and read a new disk but cannot read old ones. I have decided to try to adjust the radial alignment. I have access to a DYSAN alignment disk, PAT-1 tester, and scope. My problem is lack of documentation on my disk drive. Can anyone tell me which test point provide the index signal and the outputs of the read differential amplifier? Ken Wampach AT&T Consumer Product - Montgomery (312) 859-4557 Cornet 392-4557
