Most v2000 systems also used relative hub rotation speeds to determine where in the reel you were. The ability to make a tape read-only then change it back to read-write was nice as well for those of us who primarily used it for recording. It also had space for a data track and in theory better 'inter-player' compatibility. I vaguely recall rumours of an auto reverse function in the design stage although gawd knows how that would actually have worked. A video read/write head doesn't seem like it could be seamlessly turned on its head.
We had a couple of v2000 machines back in the 80s.
Sadly cost and being late to the party killed it off.
