a quick google search brought up nothing on Audio Magazine. Do you still have that issue Garrard201? it would be an interesting read. an inspection of this tape case reveals a side A and a side B. the case is very similar to a cassette, but much larger. the notch at the top/center of the case is a release for the hubs. the slots next to the hubs are windows. the slots near the heads are open, and possibly control the machine's auto-stop like a reel to reel does. i do believe that this tape would play on a reel to reel. i wonder what the tape speed is? unfortunately, it appears that the case is glued shut. opening the case would damage it, even if i were careful. i could cut the tape, but i might lose program material that way. the tape has been stored in its box, in a shoe box, on the shelf of a closet for all these years. i only hope the recording has not deteriorated. i would much rather find the proper machine to play this with.
if this turns out to be extremely rare, i'll find a way to post better pics!
