RCA's decision to use a groove in order to elminate a servo
control was IMO their biggest mistake. The JVC [Japanese Victor]
had a data track and an embedded servo track and stylus rode over
the top like a sled.
To save money RCA used the capacitance method for only the video.
In lieu of servo they used grooves on the disk. The stylus rode
in the groove and the cartridge in which the stylus was mounted
was attached to an arm which was desgigned to be perpendicular
the groove.
The arm had a hole with bearing through the back of the arm, and
through the hole was a rotating shaft. As the stylus tracked
the arm ceased being exactly 90 degrees to the shaft and small
'wheels' then contacted the shaft and were set in motion by it, and
moved the arm in the direction of the stylus movement to bring it
to be perpendicular again.
The idea was to save money by using what amounted to a mechanical
servo. Big mistake. Not knowing the engineering decisons which
caused this, the choice may have been made early in the game
where the electronic servo in the JVC was not seen as financially
feasible.
Previously RCA had dumped $400,000.000 in reasarch on developing
their own VCR before scrapping it and buying the VHS technology.
At this time RCA also seemed to have 'revolving door CEOs', where
the head man seemed to get change every coulple of years. One of
the first moves the new person in charge seemed to do, was to kill
projects from previous management.
This, in my opinion, is why RCA exists only as brand name for
a consumer electronics division of Thompson of France in the
consumer electronics market. [The RCA CD's brand is owned by
Berelesman's music division - BMG].
I alway thought it was ironic [I guess that's the word] that
the brand RCA - which stood for Radio Corporation of America
wound up being owned by a company that was at least partially owned
by the French government, given that in that era the French did not
seem to particularly care for anything American.

VHD had a very good run in Japan and was used primarily for Karaoke, although
there were many movies released as well. Yes, it is a good system and was
designed by the same group of engineers that invented the original VHS
system. Mr. Inoue, since deceased, was a visionary engineer at Victor and
gave much of the incentive and funding for development of VHD. I know some
of the engineers who developed the system and they are probably available for
Q and A if any one is interested. There are many sources of VHD discs and
players; but mostly in Japan. If anyone wants more information, let me know.

HI,
For VHD information in Japan:
Best place to start is maybe Mr. Vic Goh, retired, but still working in
Japan. He was with Victor for many years, both in USA and in Japan, and has
lots of knowledge about VHD (and even more about CD-4).
His email address is:
vic-goh@cityfujisawa.ne.jp (Vic Goh)
and I think he can put you on to some of the collectors and others who are
still active with VHD. If Mr. Goh does not reply with sufficient information,
please let me know and I will refer you to others, but Mr. Goh is personal
friend of mine and is very nice man.

For sale - RCA CED Videodiscs (obviously not LaserDiscs)
All appear to be in decent shape, some really good, and some are more shopworn-
someappear to be previous rental copies. Who knows, maybe they all were, but
I doubt it. I am unsure because I am not the original owner. Some have little
video rental labels, some don't. I have a USB PC camera on my system so I can
take photos of any title or titles you wish to see. I have no player
unfortunately so I can't offer a guarantee of condition but if anyone is
willing to swing by Sacramento, California with a player you may play any or
all of them if you wish.
That being said, I will list the titles - Some are two disc movies - please
note, a couple of the two disc movies are missing one disc. I will note the
UPC number for each disc and notate if a disc is missing. Most stickers are on
the front unless I note otherwise. As physical condition varies and you are a
serious buyer please feel free to ask for some photos of the disk to ensure you
will be satisfied with its condition. I would rather have these sit here
forever than have you unhappy.
