ABSTRACT:
A video signal reproducing device for use with a magnetic tape has at least one rotary magnetic head which reproduces the video signals recorded in slant tracks on the tape and a tape transport mechanism which drives the tape at controllably varied speeds. A first circuit selectively generates tape speed signals indicative of respective speeds of the tape. A second circuit selectively generates duration signals indicative of the time periods during which the tape is driven at the respective speeds. A memory stores the tape speed signals and the duration signals, and a system controller connected to the memory controls the tape transport mechanism to drive the tape at speeds and for durations determined by the tape speed signals and the respective duration signals read from the memory.
