Abstract

Width of a write track for a magnetic tape head is measured by writing a foreground magnetic track signal on a magnetic tape having a dissimilar background signal. A magnetic tape read head is moved from beyond one edge, laterally across, and beyond the opposite edge of the foreground track signal. Logic detects the read head encountering the one edge and the opposite edge of the foreground track signal; and determines, from an independent position sensor, the width of the foreground track signal as the lateral distance between the lateral position of the read head at one edge, and at the opposite edge of the foreground track signal.

Description

[0001] reference documents [0002] Commonly assigned US Patent No. 5,946,159, which is incorporated herein by reference, shows a track following servo system for tracking servo track edges of different servo signals and employs non-servo or independent position sensors. Commonly assigned US patent application 10 / 035,182, filed January 4, 2002, shows the injection of prescribed signals into a servo system to calibrate the servo position using an independent position sensor, which is incorporated herein by reference. technical field [0003] The present invention relates to magnetic tape systems for storing data on magnetic tape, and in particular to determining the write track width of a magnetic tape head, wherein a plurality of parallel tracks are written to the magnetic tape. Background technique [0004] Magnetic tape systems provide convenient and low-cost data storage. As an example, portable tape cartridges can be shipped from a data storage drive of one data process...
