Variable-speed reproduction, i.e., still, slow, and shuttle reproduction capability, is an important function in the practical use of a digital VTR. During variable-speed reproduction, the playback heads scan across the plural signal tracks, and the relative speed between the heads and the tape changes from normal speed. The optimum parameters of both data format and tape format have been investigated, and a new scheme for a timing circuit has been developed. The results of using an experimental digital VTR are described.
