<p class=MsoPlainText>Just to provide the other view. The doors covered
the tape fairly well. These were the 3 minute versions, but the one
minute carts were more commonly used. It was interesting that Scotch 400
tape was used and recommended. When 420 came out, it clearly had a better
picture with less noise or “chroma spread” but the tape had serious
issues with “stiction” in the machine. The smooth surface against
the posts and audio head assembly caused the tape to stall after it was cued
and ready to go. I spent quite a bit of time at customer sites sorting
this out after they rebuilt carts using 420 tape. It was easy to
demonstrate. Too bad since the picture was noticeably better. <o:p></o:p></p>

<p class=MsoPlainText>While both RCA and Ampex carts produced proper quad
recordings, I’m fairly certain the procedure of removing the tape and
playing it on a quad was seldom used. Even at our low end station, we
always had the original quads on the shelf. It would have been a lot of
trouble to actually perform the complete task. And they wouldn’t have
easily been interchangeable between machines since both used a different method
of cueing (timecode vs. tones) and the end of tape sensing would have been
different. Not efficient in any case. We were luck to have either
of these machines in the day as it really freed up the manual task of loading
2-4 quad machines for a break.<o:p></o:p></p>
