Destructive Imaging of DECTAPE II Media

It has been over 2 years since I last used my TU58 tape drive, but it was still working then with (of course USABLE) TU58 tapes, although a good percentage were no longer in that category. If it seems reasonable, I can try to see if the TU58 tape drive will still function correctly. If the TU58 tapes which need to be recovered can still be read by a TU58 drive, then I could undertake to recover those ones. Note that I am in Toronto, so postage would be MUCH more than within the US. Unfortunately, there is no visual difference between tapes which can still be read and those which have errors that can't be recovered. But if the tape can't even be moved or the drive belt is broken, either of those problems would prevent a standard DEC TU58 drive from being able to recover any data from the tape. Jerome Fine
