Abstract

Prerecorded magnetic tapes can carry periodic patterns which identify the combined skew affect of the head, drive and tape combination between the outer tracks. The recording channel system then detects and sets time delays for a zone or zones of the earlier arriving outer tracks. The time delay may be set as a constant or as a variable. The periodic patterns identify the combined edge track to edge track azimuth skew and identify which edge track is the earliest.
