|LabGuy's World: 1967 Sony CV-2200(A)
- Editing & Duplicating Videocorders
New Additions - 01/00!
1967 Sony CV-2200 & CV-2200A - Editing &
bring dubbing and editing facilities to the Sony skip field family of VTR's.
The "A" revision in the suffix of the second unit is just a slightly more
improved version of the CV-2200. All of the differences appear to be internal.
So the two models can be considered exactly the same from the users' stand
special dubbing cable, model VDC-1, two of these machines could be coupled
together for editing or duplicating video tapes. This arrangement allowed
the machines to record RF to RF directly from one tape to the other. The
term, "RF", refers to the signal just as it goes onto or comes off of the
tape right at the video heads. This removes many of the steps and circuits
necessary to demodulate the signal back down to baseband video only to
have to remodulate it back to RF again in the recorder. This improves the
signal quality of copies dramatically and the process is used in analog
VTR's to this very day. Synchronizing signals are taken directly from the
player's head drum servo circuits and used to directly control the record
machines servo circuits. This method minimizes errors introduced by the
mechanical part of the tape transport system, improving time base stability
of copies and the servo lock up time of the decks.
can say about that is, "Those Japanese people are so darned clever"!
