There were about half-a-dozen others which used 1/4" tape. I haven't the
time to properly identify and list them, but they share one attribute in
common. The tape can be removed from its enclosure, wound onto an empty
reel, and played back on a reel-to reel with one of the then-normally
available head configurations. The great advantage is that you can use
machines which have a minimum of tape motion ills built in.
I have one system that put two 5" reels into a metal case, making a 18 wheel
versuion of the audio cassette. It's in a box somewhere.
