Abstract
A disk drive is disclosed comprising a head actuated over a disk comprising a plurality of tracks. Data is read from a target track, and an off-track read capability (OTRC) is generated for a plurality of segments of the target track. For example, an OTRC may be generated for a plurality of data sectors, wherein the combined OTRCs may be evaluated to compute an average track center, or an average track width, or a repeatable runout (RRO).
