Hello again!
I'm not sure if this belongs in General or Repair and Restoration, so feel free to move this thread Tezza!
A few months ago, I got this massive magnetic tape reel from a local art studio when they were clearing out their storage room and I've never really known what it was.
It might be a video tape of some sort, or a data tape. I've got no clue, as this is WAY before my time, and still a wee while before my vintage computers were made too.
Here is a link to some photos. The only markings on the tape is the brand, Scotch, and in vivid, 7 Phil. http://imgur.com/a/CLYJn
The tape is in very good condition under the top layer.
Any idea what it might be?
