An old disk shouldn't have affected the head alignment, but it may have made the heads dirty. You should be able to gently clean them using a long cotton bud (used for cleaning babies ears and so on) and some (pure) isopropyl alcohol. Or get a 5.25" disk cleaner from e-bay (something like <http://www.ebay.co.uk/itm/NEW-5-1-4-FLOPPY-CLEANER-AND-3-1-2-FLOPPY-DISK-DRIVE-WET-DRY-HEAD-CLEANER-/141071603708?pt=LH_DefaultDomain_0&hash=item20d885d7fc>).

Dano is the guy to talk to on this subject. He's done a LOT of data recovery of old diskettes, and as you've found out, some of these old diskettes can only be read once before the media starts to flake off, scratching the heck out of the disk, totally ruining it. It's a MUST to clean the heads after EVERY reading. It may be a pain in the backside, but if you want to get anything off the next disk, it's a precaution you have to take.


Good Luck! I hope you find something rare and valuable, or something that has been lost to the community for decades. :)
