1977?: IVC 800A(SMR) One Inch Color Video Recorder and its Video Head!
        Another artifact from International Video Corporation. Introduced in the mid 1970's, this is a stand alone full color VTR. A second feature is slow motion playback capability. The first photo shows the top of the transport, the second photo is a close up shot of the scanner assembly and the last photo is of an actual video tape head. The one inch wide tape is wrapped completely around the head drum, traveling in a counter clockwise direction, entering at the lower left and exiting at the lower right (of the image). Since the feed reel sits lower than the take up reel, tape travels "upwards", in a helix, as it traverses the circumference of the drum. This scanner has only one video head, which protrudes a minute distance from the drum, and contacts the tape. When running, the scanner spins the head around 60 times a second in B/W mode and 59. 94 times per second in  color. The rear portion of the  video head is visible inside the drum at about the "9 O'clock" position. 
       This machine also has two audio tracks, one of which (channel two) can be re-recorded after the fact. There are controls to set both audio and video input and output levels and meters to monitor those. There is a separate control for color lock and another for variable speed slow motion playback. Additional controls are provided for tracking and tape tension adjustments as well. The connector panel contains jacks for video input, color (corrected) video output, raw (unprocessed) video output, audio inputs and outputs, AC power and remote control. This machine is heavy, weighing around 75 pounds (34 Kilograms).
WANTED: Vintage magazine articles or any other information on this and any other IVC machines.
