ABSTRACT:
A system for recording or playing back a television signal which includes an audio carrier which is frequency modulated with an audio signal, the television signal being recorded along oblique tracks on a magnetic tape and including two playback or recording heads which alternately scan successive tracks. The system includes a controllable amplifier connected to conduct the modulated audio carrier signal, and circuitry connected to control the amplifier for causing it to produce an audio carrier signal during switching between heads in order to reduce interference in the audio signal during such switching.
