One more question, what is the best way to clean the
heads?
DO NOT TRY TO CLEAN THE HEADS!!!!
Read the documentation in the cdc and dec sections of bitsavers
on these drives.
3330 style heads fly a LOT lower than RK or RL heads, and they
warn not to try cleaning either the packs or the heads because
it is impossible to get all of the residue off of them.
