Recording and reproduction equipment for TV - has magnetic discs and units to process still pictures

摘要

The TV signal recorde and reproducer is used to obtain still pictures, and uses digital techniques. It comprises magnetic discs to record and reproduce video signals. It has a disc turn-table driven at constant speed. It also has transducers to record the signals onto the discs or to reproduce the signals from the discs. Each turn-table has a transducer and a unit to convert a video signal into a digital signal. The signals are then sent to transducers on separate surfaces of the disc. The unit may also convert digital signals from the disc into analogue signals and reproduce pictures. It also has a time base corrector, a data transmission unit and other units.
