1. Apparatus for recording a video signal in a plurality of tracks extending obliquely on a longitudinally advanced magnetic tape, said video signal occurring in successive predetermined intervals, said tracks being at a uniform predetermined angle with respect to the longitudinal direction of the tape and having a uniform predetermined pitch and each including one said predetermined interval for representing a standard track format, said apparatus comprising:

  • means for generating at least one synchronizing signal of variable frequency;

    means for determining said variable frequency in accordance with a desired mode of reproduction;

    camera means including image transducer means from which said video signal is obtained in correspondence to incident light from an object image projected on said image transducer means, and means for transmitting said video signal from said image transducer at a selected rate;

    recording means including recording head means repeatedly scanning across said tape for recording said transmitted signal thereon;

    tape drive means for advancing said tape in said longitudinal direction while said head means scans thereacross; and

    means for controlling said selected rate and the speeds at which said head means scans across the tape and at which the tape is longitudinally advanced, respectively, in dependence on said variable frequency of the synchronizing signal so that the tracks are always disposed on said tape regardless of the speed of advancement of the tape.
