Title: Video signal reproducing apparatus with a track searching arrangement

Abstract: In an apparatus in which video signals recorded in successive parallel tracks extending obliquely across a magnetic tape are reproduced by means of at least one rotary magnetic head which scans the tracks in succession at a rate dependent on the speed at which the tape is moved longitudinally by a tape transport assembly; a track searching arrangement is provided that includes a selector actuable for selecting a track searching mode of the apparatus, a manually rotatable wheel or dial, and a control circuit for initially establishing transport of the tape in the forward direction at a normal speed upon actuation of the selector, and for thereafter varying the speed and direction of transport of the tape from the initial speed and direction in accordance with the direction and angular extent of any rotation of the wheel from the position of the latter at the time of selection of the track searching mode.
