[QuadList] AMPEX VR-5100 WILL IT PLAY OTHER MACHINES TYPE...

[David Crosthwait]

Hi Ed,

I'm continuing to have problems with this list via G Mail. I don't know if you will be able to read this from the Quad List.

Each of these vintage tape format recoveries does depend on the physical nature of the tape stock. Generally speaking, A format stock issues are compounded by the guide situation (different tape geometry on every guide engagement potentially). Except for the VPR-1 transport, the handling of tape is somewhat rough at times. Since it can generally be agreed upon that 1" helical videotape formulations were a learning experience at that time from a manufacturing standpoint, tape quality out of the box, it's ability to survive the rigors of an A-format transport usage and long-term archival survivability were moving targets in my opinion. Over the years, each tape manufacture made improvements in 1" helical stock (3M the greatest in my opinion). When type C was adopted, then we really saw 1" stock become professional with further improvements.

EIAJ tape stock has not been as problematic for us being a later format but it can have it's challenges, especially when Karex is encountered.
