Woa...
No, message 8 above is wrong.
The machine has 4 tracks over the one and only magnetic side of the tape, so each track will be less than 1/16th". When you record, you use tracks 1 and 3, which are not adjacent on the tape (looking the same way at a cassette recorder, there you use tracks 1 and 2 one way, and 3 and 4 the other side). Then NORMALLY to play the other 'side' (which is actually the same magnetic side of the tape) you turn the spools over which means that what WAS tracks 2 and 4 now become 1 and 3 (like turning over a cassette) and away you go. If this machine has auto-reverse and a second play head, then the machine will play the other way and you don't need to manually flip the reels, and the second head will be aligned to read tracks 2 and 4. I assume though that it will record ONLY to tracks 1 and 3? Auto-reverse is playback ONLY.
I hope that's a bit clearer.
