Hi, Steve, and Marcia,

I recall Dick Cavett being on ABC. I worked at ABC. I've heard some of 
the logging tapes from the 1970s and know how they were made and how 
they sound.

They were 4-track (possibly 5-track counting time code, I don't recall) 
recordings in one direction. Both local (WABC-TV Channel 7) and Network 
were recorded. The other two tracks escape me. One may have been time 
code, though I have a 5-track repro head which allegedly was used as a 
format to provide four logging channels PLUS time code. But I got that 
head in the early 2000s from Joe Dundovic who made it at Nortronics.

The recording was on Maxell 18 micron ("1/2 mil" with thin mag coat) 
tape which means 3600 feet on a 7-inch reel. Tape speed was 15/32 in/s 
providing 24+hours per reel. Dual Dictaphone (I think) transports 
alternating days.

Those transports were designed more for 35 micron ("1 mil" with a 
thicker coating) tape with 3600 feet of that tape requiring a 10.5 inch 

The end result exhibited very high flutter and very poor frequency 
response. The 18 micron tape was especially springy and its contribution 
to the poor flutter performance was my conclusion back in the day. But 
the 10.5-inch reels were more expensive and took up more space and 
fidelity on logging tapes was not a hill to die for. Even I understood 
that way back then. I tried much harder to have all 1-inch Type C video 
tapes recorded with Dolby A. Whether that would have been a good 
decision long term, I don't know as there are plusses and minuses, but 
the Type C audio had about the same S/N ratio as a cassette, if I recall 

Even if the tapes did exist, I'm not certain I'd want to listen to them. 
If you were lucky and I played the tapes on a Sony APR (not a 
Dictaphone), the interview segments might be tolerable, I think the 
music would be like fingernails on a blackboard or worse, and I'm not 
making a comment about Joplin. I actually like some of her music though 
I'm more of a Judy Collins and Joan Baez fan.
