This paper describes the recording and replaying of digital video signals using a computer-type disc-drive as part of a system being developed to enable animated picture sequences to be generated for television, where at present film is used.The characteristics of the disc-drive are described together with data processing, error protection and signal synchronization systems which enable digital television YUV component signals, sampled at 12 MHz, 4 MHz, 4 MHz respectively, to be recorded and replayed in real time.
