Hi there,
 
These 1/2 inch machines came in 2 generations, the CV series which were
propitiatory skip field machines, so only played tapes recorded on
another Sony CV series machine. All of the Japanese manufacturers did
that at the time.
 
Then they standardized to the EIAJ-1 standard, full field machines, and
all of the makes made tapes that would interchange. the Sony machines
were the AV3400 (luggable) AV-3600, AV-3650, and later color machines
AV8400 (luggable) and a AC operated one as well (AV8650?)
 
As I recall from my high School days in the later 1970's, the
mechanical design was similar to the audio reel-to-reel machines, with
idlers and belts. The slip rings on the rotating heads needed attention
too.
 
Please note that all of this info is for USA market NTSC (Never The
Same color) machines, and is subject top the (in)accuracy of my memory
of 45 years ago.
 
Best regards,
Tim Schwartz
