Ampex videotape recorder type VR 1000A

Radio Communication

Ampex videotape recorder, type VR 1000A, serial number 329. Since television signal contained frequencies up to about 5MHz, the speed at which the tape passed the head must also be very high – much higher in fact than the speed at which it was practicable or economical to move the tape from reel to reel. In the case of the Ampex VR1000, this problem was solved by causing the four heads to sweep rapidly across the tape, whilst running the tape at only 38cm/sec. In this way, the signal was recorded as a series of narrow tracks across the tape, the head-to-tape speed being about 100 times higher than the forward speed of the tape. The heads were carried on a rapidly spinning wheel. The double bay of equipment with the console contained control equipment necessary to ensure a steady picture: servo-mechanisms and their associated electronics for controlling the speed of tape movement and head-wheel rotation and the means of switching the replay signals from one head to another as the wheel rotated.
