ABSTRACT:
A read/write head unit is moved across a reference burst track on magnetic tape from one longitudinal edge thereof toward the other through a series of transverse locations. The peak amplitude of the output from a read amplifier, representative of the reference burst, is detected at each transverse location. The set of amplitude values thus obtained is then referred to data, compiled by testing a number of tape transports and a number of tape assemblies, representative of standard categories each comprising an allowable range of deviations from a different standard set of amplitude values and a corresponding distance to be traversed by the head unit from the last of the series of transverse locations to the centerline of the reference burst track. If the detected set of amplitude values has proved to belong to either of the standard categories, the head unit is moved the corresponding distance from the last of the series of transverse locations to the centerline position on the reference burst track, and hence on Track Zero which is aligned with the reference burst track.
