RCA Video Tape Recorders:
||RCA Longitudinal: This
is RCA's first attempt at any kind of video recorder. Developed in 1954
by Harry F. Olson. It is a longitudinal (fixed head) machine. Uses half
inch tape on 17-inch reels runnning at 360 IPS and recording 5 tracks.
1 track for video luminance plus sync, 3 tracks for the red, green, and
blue signals and 1 track for FM audio. Photo and Info: Matt Patoray.
||RCA Mag Tape: This is
RCA's attempt at a home VCR from the early 1970's. It used 3/4" tape, ran
at 3 IPS and recorded 60 minutes on 918 feet of tape. It used a four head
scanner that intruded into the cassette housing. Signal processing was
alleged to be direct recording, like a broadcast quad machine. This machine
never went into production. The previous information is from my own memory.

SelectaVision MagTape System - RCA TO MARKET COLOR VIDEO
PLAYER FOR CONSUMERS
The latest home video recorder
/ player, which will be available in 1973, is the all solid state RCA SelectaVision
MagTape unit. Measuring 22" X 17-3/4" X 5-1/4", the unit has a front panel
slot to accept a 9" X 6-1/4" X 1-1/2" molded plastic tape cartridge. A
set of piano key switches are used to control the various operations. The
only connection between the player / recorder and the TV set is through
the antenna terminals. The set is tuned to an unused channel for tape operation.
The player / recorder includes
both VHF and UHF tuners so that a monochrome or color recording can be
made of one channel while watching another. An automatic timer is also
included to turn the recorder on at any desired time. There is provision
for using an external black and white camera for the "do-it-yourself" TV
producer, at home or at work.
Although the first units
will be independent of the TV set, RCA points out that they will be followed
by combination models incorporating both color TV receiver and the player
/ recorder. The final pricing will be determined when the system reaches
the selling stage, but is expected to be under $700; the cartridges will
cost about $30.
When not in use, the book
size tape cartridge is completely closed so that the tape is never exposed
or handled. Chromium dioxide (high energy) tape is used and the approximate
900' of tape in a cartridge permits about one hour of use. When the cartridge
is inserted in the slot, an internal lever opens the cartridge to permit
the tape to come into contact with the rotating headwheel (four heads).
