[QuadList] Little more fun

[Gary Adams]

Because the quad tracks were mostly (not completely) perpendicular to the
tape, backwards got some picture upside down and backwards.  You were still
reading the oxide side.  This put the control track where the audio heads
expected audio so you hear control track.  Capstan would free run without
control track.  Some clever people put 240hz tone on the audio track
allowing the capstan to be a bit more stable as a joke.  I think newer
machines did not like this too much but I'll bet the AVR1 could play it and
probably turn the picture back up  J  (just kidding).   I think on a 1" the
tracks would never line up since they were so slanted to the tape.  So the
heads would read across the track rather than with the track.

Hi Joe,

 

This was after FF to the TU reel then puting it on the supply side so it is
looking at the back of the tape, we were getting a "Nil heard signal" from
the tape.

 

Now that you mention it I do remember at some time having a tape upside down
on a machine, it did come out upsidedown, but bad picture and lock up with a
funny tone from the CTL coming out of the audio. BUt this was with the oxide
side facing the tape.

 

Mny Tnx,

 

George

[Flipping the tape over takeup/supply] On some machines, the video would
play upside down and in reverse, but no audio, obviously.

I think this would work on the 1" machines also, but I never tried it.
