Abstract
A video signal recorder/reproducer is used to record and/or reproduce pulse signals in successive tracks on a record medium. During recording, the pulse signals, which may, as one example, represent audio information, are interleaved with simulated horizontal and vertical synchronizing signals of the type similar to the synchronizing signals which normally are included in a composite video signal. During signal reproduction, the reproduced simulated horizontal and vertical synchronizing signals are detected and used to control the recovery of data from the reproduced pulse signals.
