[QuadList] Little more fun

[georgenann at aol.com]

Hi Gary,

Actualy, I think if you had the oxide side of the tape on the heads, the heads would be completely slanted in the opposite angle from the recorded tracks.  With the back of the tape on the heads, we didn't get enough signal to make any video at all.

You just rang another bell.  Has anyone run into the Ampex High Speed Dubber?? I only saw one once at EUE in New York, briefly.  I understand an AVR-1 was needed to make a mirror image tape first, then the dubs were made by putting the new mirror tape against the blank and some kind of field was shot thru them and the video was recorded on it.

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.
