- 0 - MULTITRACK RECORDING WITH MINIMAL INTERMODULATION Abstract of the Disclosure Whether for the recording of parallel or serially occurring information, the general concept of the inven- tion is to record sample (or bit) data in the form of damped ringing signals (e.g. of the form Image ) 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 longi- tudinal 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 signals may be reproduced.
