But! For some reason the above reminded me of
something that I was
considering early on, probably early 1970s or
so.
Instead of a drum just
use a loop of tape. You can start with an old
reel-to-reel deck, ignoring
Howzbout an 8-track?
Unfortunately, the kids today don't even remember
them, so wouldn't fully
appreciate the absurdity.
That actually would work pretty well, since the
mechanism already intends to have a continuous loop of
tape. You would just have to shorten it somewhat.
Waiting 12 minutes for that bit to come back around
would be a pain.
If you shortened the tape, and a somewhat shorter foil
splice and had both the record and playback heads
egaged at the same time, then you could use the foil
sensing splice/contacts and have that generate an
index pulse to start timing.
Of course, you're still limited to 2 bits wide, since
eight track tape recorders still only have a stereo
head, with a solenoid to move the head.
Now, if you could find a quadraphonic 8 track recorder
(rare as heck)...
