ABSTRACT:
A disk drive is disclosed comprising a head actuated over a disk having a plurality of data tracks. An ideal data tracks per inch (TPI) profile is determined for the disk, and an actual data TPI profile is generated that estimates the ideal data TPI profile by combining a first segment of a first predetermined data TPI profile and a second segment of a second predetermined data TPI profile.
