(International Video Corporation) IVC's
world headquarters building used to be at: 675 Almanor Avenue Sunnyvale,
California. International Video Corporation flourished from about 1967
well into the late 1980s. IVC manufactured dozens of models of VTR's, cameras,
film chains, switchers and other video equipment for the low end broadcast
and high end industrial markets. They sold equipment into virtually every
country in the world. I personally remember seeing the IVC color cameras
at TV station KRCR, channel 7 in Redding,
California, during a high school class field trip. (Click

IVC 1-11: The broadcast VTR that never was! The
IVC 1-11, 1 inch Broadcast VTR is designed for the user looking for the
performance of 1" VTRs without excessive cost and complexity. (Approximately
$36,000) Compact, flexible and simple to operate, the IVC 1-11 employed
a new signal system derived from the IVC-9000 mastering VTR, Dolby (TM)
Video processing and a dedicated integral digital timebase corrector. The
result is full bandwidth low noise video for a multigeneration performance
comparable with any broadcast VTR. The IVC 1-11 is available, with a variety
of packaging options including space saving transport and electronics assemblies
separable by up to 10 feet (3 meters).
Easily
integrated with auto editing systems, the IVC 1-11 provides high speed
tape shuttle for fast access to any recorded tape segment. All controls
for monitoring and optimization are on the front control panel with clear
meter and/or LED readouts. A microprocessor based timer with programmable
memory makes scene material location and retrieval fast and accurate. A
full range of connectors, audio on XLR, video on BNC, is easily accessible
on the 1-11's rear panel. Along with a remote foot switch brake release,
for use with any 1-11 configuration.

This machine, sadly, never went into production. Only two prototype machines were built. The IVC 1-11 is a classic case of a product being to late for its market place. By the time this machine was ready for production, in 1980, the 1 inch C broadcast format had been adopted by the television industry. This truly was the last video recorder developed by IVC. I'd like to thank William Meyer for all of the excellent IVC historical information that he has provided for us here. IVC VCR-100: IVC
VCR-100, Video Cartridge Recorder.
The VCR-100 was a video cartridge recorder and conformed to the same physical recording format as all of IVC's 1 inch reel to reel machines. A tape cartridge, unlike a cassette, does not contain an integral take up reel. Instead, the machine contains an internal, fixed take up reel. When a roll of tape weighs 6 to 8 pounds, the design engineer had to work over time to trim away the fat. Removing the take up reel from the cassette housing, and saving a pound or two, was totally logical. (More about this in a moment.) The 8" reel prior to installation in the cartridge.
The VCR-100 New Scotch 461 tape came with clear leader tape for use in this machine. The leader functioned as a component of the machine's auto threading system. The leader was removed when the tape was used on an open reel machine. Loading
the cartridge into the IVC 100.
At startup, the feed reel, inside the cartridge, would spin very quickly. In fact, it would spin so fast that it would literally launch the leader tape from the spool. The leader was then guided, by the walls inside the cartridge, to a special guide track called the "C channel". The C channel guided the leader tape around the intended tape path and delivered it to the internal take up spool, which was also spinning. The stiff plastic leader tape would remain in the C channel, but the much more flexible recording tape, would be pulled out of the C channel to drop neatly onto the guides and heads. This ingenious process, like most ingenious processes, works great. (...on paper!) . The VCR-100 had it's head drum mounted upside down. This allowed gravity to assist in the threading of the tape. This tid-bit of info was provided by William Meyer, who used to work at IVC. . If this sounds a bit like a Rube Goldberg mechanism to you, you're right! Panasonic's Omnivision format and CBS's EVR both worked this way, too. All of these formats had fixed internal take up spools. If anything went wrong and the tape or film jammed, you could not remove the cartridge! It required disassembling the machine, and attempting to rethread the tape onto the guides. Failing that, you spent the next hour or two pulling the tape out by hand and wrapping back it onto the feed reel! . IVC 500 Series VTR's: IVC-500,

IVC Video Heads:
This is an example of the video head used in the model(s) 700, 800 and
900s. If you look very closely, you can easily see the ferrite (black)
material that formed the actual recording surface. The 7 or 8 turns of
microscopic copper wire, which transform the ferrite into an electromagnet,
are also visible in the picture. This fragile assembly is glued to an aluminum
mount which is called the "boot".

3. & 5
This machine was phenomenal! It worked in ALL world video standards. It had a whopping 8 Mhz direct (raw) bandwidth! The IVC-9000 used 2 inch video tape in a Segmented Helical Scan configuration. Video was direct recorded to tape. Specifications: Tape Width: 2 inch, Linear tape speed: 8.00 IPS, Scanner Speed: 9000 RPM, Relative tape speed: 1,500 IPS. Design Team:
The IVC-9000 had one other interesting mode. It could record a 655 line picture at 24 frames per second. This is specifically for the film industry. The model number of this film frame rate machine was: IVC-9000M, the M standing for MOVIE or maybe "costs even MORE". . Does anyone have any more information about the IVC-9000, especially the 24 FPS mode IVC-9000M? If so, please send me an email. Notes / Credits: 1.
