[QuadList] VR-1006 RADAR VTR

[Don Norwood]

Hi Chris:

I have a good bit of info on RCA transverse scan instrumentation recorders 
from the same era, and I suspect they are similar.  The servo systems are 
very simple compared to a video recorder, because there's no need to lock 
the playback to anything else.  All that is required is to have the head 
track properly, so a master oscillator drives the drum in record and control 
track is recorded in the usual fashion so that on playback, the head can be 
properly phased.   Consequently, there's no requirement for the signal being 
recorded to have any type of sync.

We've had some discussions before about Octaplex recorders, head drums with 
8 heads instead of four so that they could record two different signals 
simultaneously on the same tape.  They were also used for radar when it was 
necessary to have two different signals reproduced with absolute time 
coincidence.  No fancy synchronization servo required!
