That description fits the tape system used in the HP9830. The tape transport
is actually a "DigiDeck" OEM'd by International Computer Products, out of
Dallas, Texas. The head is non-standard though, in that it R/Ws both

I don't think it would be of any benefit to the OP's interest over what he
already has to work with.=

Probably not, but I thought I'd mention it just in case; it doesn't use a
pinch roller though, and it is completely digital, FWIW.
I don't recall whether it was a DigiDeck, but ISTR that I compared the BBM
unit to another digital deck that was (relatively) popular way back when,
and I'm pretty sure that they were different.
They were mostly used with Burroughs Series L machines, but I think some of
the small B series could also be equipped with them. I've still got a few
boxes of utility, game and program tapes for Burroughs L series machine, but
working L's are pretty thin on the ground so I sometimes toy with building
an emulator; that's why I still have the tapes and the drives (although
unfortunately I threw out a lot of paper tapes a long time ago), but that
project is pretty far down on the list...
Just a thought...
