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.
Claims6
A magnetic tape recording and reproducing apparatus comprising:
- a rotary video head assembly;
- a stationary full erase head;
- a tape transport means for transporting a magnetic tape past said rotary video head and said full erase head;
- an erasing signal source for generating erasing signals having a predetermined frequency;
- a cue-signal source for generating cue-signals having a frequency lower than said predetermined frequency of said erasing signals;
- and
- a switching means connected to said full erase head, said erasing signal source and said cue-signal source for selectively connecting said erasing signal or said cue-signal to said full erase head, whereby when said erasing signal is connected to said full erase head the magnetic tape is erased and when said cue-signal is connected to said full erase head a cue-signal is recorded on the magnetic tape.
