[QuadList] Non-Contact Extraction of the Program from Quad Tape - Ampex non-moving head

[C. Park Seward]

I attended a SMPTE conference when Mark Sanders, GM of Ampex audio- 
video division, talked about some experiments that Ampex was dong. One  
was a non-moving type "C" record head. The concept was to have the  
magnetic field move up and down the stationary head. Many of our Asian  
friends were taking copious notes.

The quad head pushes so hard into the tape that the documentation  
talks about the "tent" shape that is caused by the penetration. The  
heat generated is tremendous. So a stationary head would cause much  
less damage to the tape.

The next question I have is how good is the playback? Does an AVR-1  
recover everything on the tape? I would suggest yes but there may be  
something more there.

Best,
Park
