Abstract
In order to record audio signals on a magnetic record carrier, there is produced a high frequency pulsed signal which contains the low frequency information pertinent to the audio signal. This high frequency pulsed signal is produced in a manner such as to be substantially free of any signal component which has a frequency lying in the frequency range of the low frequency audio signal. As a result, cross-talk produced during recording on a plurality of tracks can be substantially reduced.
