[QuadList] OT-RCA MR-700 slant track recorder, 1961

[Don Norwood]

Ted:

Well, it's not as large, but the scanner on the Ampex VR-8000 was no tiny thing either!  Here's a pic of it with the scanner cover open that I took at the Ampex museum.  This would have been contemporary with the RCA, but was all solid state except for the audio section.  Incidently (and keeping this on quad topic!), the same tube-type audio that's in this machine was also used in the very first introduction of the VR-1100, although I think all of the production versions had the solid state audio.

  Can't tell why the link's don't work. Both work for me, but that may be from my cache.


  Cliff B reports on OldVTRs that he mailed them to himself, then posted to OldVTR's and they worked, but then so did the original links in my e-mail to OldVTR's.


  He said "???"


  The head assembly is HUGE. Looks almost or slightly bigger than the tape reels on the machine. I'm thinking that's a very long track that would be really fun to keep a head in the center of.

    The links below don't work for me.  They just go to a logo page for oldradio.com.  I looked at the site but could not find what you have described.

    I have some RCA technical papers and pictures of the helical head assembly that was used.  Don't think it ever became a real product for television, but may have been used some for wideband recording.

      What does anyone know about the RCA MR-700 slant track recorder from 1961?


      It's pictured here in material distributed at the 1961 NAB in Washington, DC:
