Digital magnetic recording has always been considered as one of the most promising techniques to be applied to television. The high bit rates involved used to be by far the most difficult problem, but many experiments have now demonstrated the feasibility of sufficiently high bit rates together with reasonable medium consumption. Such high packing densities, implying narrow tracks, seem to have solved the bit rate problem but others still remain. Attention is now focussed on the operational requirements that a digital VTR must satisfy, emphasizing variable speed playback and picture in shuttle capabilities in particular.
