Abstract
A magnetic tape recording and reproducing apparatus provided with means for recording a cue-signal which serves to mark a predetermined point of a magnetic tape on which video signals are recorded by a rotary magnetic head. The cue-signal is recorded by a full erasing head by supplying thereto a cue-signal current having a frequency lower than the frequency of the erasing current. For example, the cue-signal current is generated by using the control signal for synchronizing the rotation of the rotary head with the tape movement.
