Abstract

A recording and/or reproducing apparatus for video signals, equipped with a rotary head system that scans, in the direction of the tracks, a recording carrier and comprising at least one recording and/or reproducing head and at least one erase head to erase, in the direction of the tracks, a registered video signal, characterized in that in an apparatus in which the tracks in which the video signal is registered cross at least one other track in the carrier For recording, the transmission path for the erase signal to the erase head includes a gate circuit that is controlled by a source of pulses, the pulses of which are intimately related to the field synchronization pulses of a video signal at register and which appears in a fixed time relation with a specific position of the erase head in relation to the other track to be crossed, and by a switching device s Subsequent, whose performance is delayed in relation to the moment in which the impulses from the impulse source appear, in a time delay that corresponds substantially to a time interval τ 1 between the moment in which an impulse appears from the impulse source and the instant at which the erase head reaches the other track to be crossed, while the duration of the switching time process of said switching device is substantially equal to a time interval τ 2 required by the erase head to scan the track to be crossed, the gate circuit interrupting the transmission path to the erase head during operation of said switching device.
