If I were you,I would specificy the reel diameter and
the certified
density. The tape I'm looking at at this instant, says on the label "3M
Scotch 777 6250 bpi", so in this case I would say "7 inch reel, 6250 bpi"
I just pulled one out, and I rather assume all are the same.
This one says Endura 800 BPI to 6250 CPI BASF
It has an inner diameter of about 3.5" and an outer of about 7"
A quick look on ebay last night turned up some disappointing results. It
seems a bunch of 9 track reel tapes failed to sell in the last 30 days.
Maybe I'll try them on the Vintage list instead.
