Occasionally, I extract data from 9-track tapes with densities
of 1600 and 6250, using an HP3000 system and 7980XC tape drive.
Recently I received 4 tapes from a PDP-11, RSX-11M, created
with backup (BRU format), that I instantly get media read
These were created about 2 weeks ago, so not old tapes.
(Well, not old backup, not sure about age of tapes!)
Because of the "older" system, I am suspecting that they may
be 800 bpi tapes.
So I am asking for some enlightenment from those of you who are
more familiar to PDP-11s about tapes and possible reasons
I may not be able to read them?
possibility of 7-track
unique tape format
actual media error (on all 4 tapes)
