I use a small Sony microcassete recorder that has two tape speeds, 1.2 and 2.4 cm/sec. As I use this only for voice recording, and "High fidelity" is not required, I was wondering if I could somehow slow the tape speed to 0.6 cm/sec. The recorder is powered by 3VDC (two AA batteries). Obviously, the electronics (amp, etc) need to keep getting 3V, but how is the motor speed reduced? Is it a simple voltage cut? I don't care about wow and flutter as long as I can understand what is recorded. Right now, at 1.2 cm/sec the sound quality is excellent, and I'd like to be able double my recording time if possible. Any ideas on how to slow the tape speed to 0.6 (or 0.3?) cm/sec? Thanks. --keith
