ABSTRACT:
A self-aligning configuration for establishing precisely where each of any number of tracks is to be recorded on a magnetic tape, utilizes therefor a photosensitive element (of perhaps even coarser structure than that of a given track), the signal output of which constitutes a measure of the location of the track(s). Thereafter, tracking control, say during playback, is pursuant to such signal, which is memorized.
