<DIV>Hi Steve:</DIV>
<DIV> </DIV>
<DIV>Both RCA and Ampex built transverse scan recorders with 8 heads.
There were designs that had all 8 heads on a single drum as well as designs that
had two drums sandwiched together. There were many different applications
for these and machines were manufactured starting in the early
'60's. In addition to the 8 head versions, there were also a variety
of slow speed designs which had some unique headwheels, some even utilizing belt
driven drums! I've collected some head assemblies as well as some
documentation on some of these systems, and included a few pics below.</DIV>

<DIV><STRONG>Here's a "late model" RCA, 8 heads on single drum</STRONG></DIV>

<DIV><STRONG>And then an RCA Belt driven design. Note the slip rings on
both ends for balanced circuits on all heads.</STRONG></DIV>

<DIV> </DIV>
<DIV>If I ever get all the videotape machine info on my website, I may start a
section for other transverse systems. There really were some interesting
designs through the years.</DIV>

<DIV><FONT size=2 face=Arial>While the RCA headwheel discussion was going on,
I was reminded of the RCA 2 channel, 8 head machinhe that was built for some
radar recording on the USS Chicago Missle Cruiser. </FONT></DIV>

<DIV><FONT size=2 face=Arial>While I was stationed at 32nd Street in San Diego
1970, at the inactive ship facility, it was removed from the Chicago, over at
North Island and put into salvage and disposal for the surplus
sale.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Somebody must have bought it for a nickel a
pound. I can remember slowly turning the headwheel and counting 8
heads. I did some asking around and found out that it was used for radar
recording and was especially set up for two channel.</FONT></DIV>
