ABSTRACT:
Whether for the recording of parallel or serially occurring information, the general concept of the invention is to record sample (or bit) data in the form of damped ringing signals (e.g. of the form (sin x)/x) and to provide relative delay between the recordings of adjacent tracks so that the principal peak of one recorded signal falls on a zero crossing of another, and vice versa. Since the peaks of no two adjacent signals occur--in the case, for example, of magnetic tape--at the same longitudinal position of the tape, isolation between the signals--as recorded on the tape--is effected. By suitably sampling the signals on the tape during playback, the original signal may be reproduced.
