1. I recently watched a DVD
Analog: The Art & History of Reel to Reel Recording
by Vision Laboratories. It refers to the magical sound
of the quality of analog recording.
It covers from the earliest days with
Valdemar Poulsen to modern multitrack recording.
Unfortunately it is amateurish in presentation
with shaky and blurry graphics. Still the likelihood of a major
studio doing the subject is nil so we have to take it as it
It bills itself as Analog The Art
& History of Reel-To-Reel Tape Recordings.
It mentions 1-7/8, 3-3/4 and 7-1/2 ips
tape speeds but no other. Reel sizes of 3, 5, 7
and 10. Actually 10-1/2
It says Fritz Fluemer invented magnetic
tape. Thats Pfleumer.
It says that noise from tape comes from
the friction of the tape rubbing against the record head. Actually
its the irregular magnetic domains on the tape.
It says that harmonic distortion in tape
recording causes bass increase. (?)
It refers to the dbx "compounding"
technique. Thats companding.
It mentions Studer and Stellavox and Nagra,
but no mention of the Revox recorders which were very popular
It is a DVDR but this is not mentioned
anywhere. They have limited life expectancy. It is 50 minutes
long (billed as 60).
The image on the cover is of Ampex 456
Grandmaster tape. However there is no mention of the fact that
many of those tapes became unplayable due to Sticky Shed
Some multitrack digital tapes from the
early days have become unplayable.
I was interested to learn that the first
pre-recorded tapes came out in 1949.
It concludes with an amusing ad for the
3M Wollensack recorder featuring solid state transistors.
The company has 3 other similar videos.
