Abstract
A magnetic video reproducer outputs a plurality of pilot signals having different frequencies from a servo circuit (18) in a recording mode, to superpose the pilot signals on video signals outputted from a signal circuit (25) and record the same on video tracks provided on a magnetic tape. In shifting a mode from the recording mode to a stop mode including a pause mode, a capstan motor (19) and a reel motor (20) are reversely rotated so that a cue signal is recorded by a cue head (10) on the magnetic tape in the form of a pulse train, whereafter travelling of the magnetic tape is stopped. When the stop mode is released, a CPU (170) determines whether or not pilot signals reproduced by reverse transfer of the magnetic tape and pilot signals to be newly recorded coincide with each other in frequency and in phase to reproduce the cue signal upon a determination of coincidence, so as to re-start recording operation when the reproduced cue signal is correlated with the cue signal recorded in shifting to the stop mode, thereby to perform program search for a recording starting position.
