ABSTRACT:
Methods in accordance with embodiments of the present invention can be applied to determine a width of a data stroke along a rotatable medium of a data storage device. In one embodiment, the width can be determined by measuring a distance from a marker zone edge of a template pattern to a ramp, and measuring a distance from the marker zone edge to an inner crash stop. A track layout can be determined based on the width of the data stroke.
