Abstract: The tendency of TV broadcasters to rely increasingly upon videotape record/ playback equipment to solve the complex problems of daily program operations as well as generation of specially assembled program material creates new performance requirements for the equipment, particularly in the area of servo systems. The new performance requirements are described, such as improved stability of the record servo system for high-quality recordings, increased dynamic range and correction bandwidth of the pixlock servo, and ability to cope with nonsynchronously switched recording intervals with minimum visible playback disturbance. The advent of new circuit techniques and system design philosophies such as the utilization of digital process control, digital servo error detection and a high-efficiency “hybrid” power amplifier has enabled the design of a new capstan and headwheel servo system which meets the above-mentioned requirements.
