Calibration of writer offset using media dimensional stability
Last updated:
Abstract:
In one embodiment, a method includes writing, using a magnetic head, a set of parallel shingled tracks onto a magnetic recording tape using specified drive parameters, changing one of the specified drive parameters, reading a set of selected data tracks on the magnetic recording tape using the changed drive parameter, changing a lateral head position while reading the set of selected data tracks using the changed drive parameter, comparing track error rates observed during reading at the different lateral head positions, selecting a reader offset value based on the comparing, and performing a further action using the selected reader offset value.
