How about an approach similar to the Sinclair
Microdrive, using an endless
loop (curled up in a zigzag fashion inside the cassette)? That way, seeking on
the tape should be easier, since you'd only need to be able to roll the tape
in one direction without any rewinds.
Well, there are special cassetes available for answering machines
and/or voice services. During the last years most of said apps
have been replaced by digital recording, but replacement tapes
are still available... usualy they have only a very short length.
the maximum I know is good for 5 minutes - most are only good for
30 seconds.
