Formatting Digital Tape - Stefan Hauschild - 11-29-2002 Does someone know how to format an 82161 digital cassette on an HP71B? The commands in the original manual are not described very well. Perhaps one needs a general decription of HP-IL. Bye

Re: Formatting Digital Tape - Raymond Del Tondo - 11-29-2002 Hi, the command is INITIALIZE(':TAPE') but I don't have any other parameters here right now.

Probably a bad tape - Mike - 11-29-2002 That is the usual message you get when you have bad media (tape). I have heard that most bad tapes are the felt pad but I have my doubts. I have some that behave this way, and the felt pads are great condition.
Very many of these old tapes are bad. I'm not sure what the percentage is but I have more bad ones than good ones.
Re: Probably a bad tape - Stefan Hauschild - 11-30-2002 I think it´s the common problem with the tapes, too. But I am happy that my drive seems to be ok. Now I can try to refurbish the tapes like mentioned some threads before. Bye

Re: Probably a bad tape - Tony Duell - 12-01-2002 When the pressure pad in a 82176 cassette fails, it's not the felt that goes, it's the foam pad under it. The felt will still look fine -- it is fine. Re: Probably a bad tape - Stefan Hauschild - 12-03-2002 Hi Tony, you are right, the felt is some sort of spinning around in the holder. But I thought it gets pressed by the read/write head. I will try to replace it from a part of a normal Cassette. Do you have any hints how to open the HP cassette without destroying it?
Bye... Stefan
Re: Probably a bad tape - Tony Duell - 12-03-2002 To open the HP cassettes, I normally use a non-magnetic tool (e.g. the handle of a cotton bud) inserted in the small square holes at the ends of the 'window' side of the cassette. And then prise (pry) the housing apart. Once it's started to separate, I run a finger nail (or if it's really well stuck, a thin blade) round the joint. |
