International Classification:

G11B 2736

US Classification:

360 31, 360 48, 360 7708, 360 7814

Abstract:

A disk drive is disclosed comprising a disk having a plurality of tracks including a plurality of data tracks and a plurality of reserved tracks. A plurality of embedded servo sectors are dispersed circumferentially around the tracks, the tracks are banded together to form a plurality of zones, each data track comprises a plurality of data sectors each having a first number of bits for storing user data, and each reserved track comprises calibration sectors each having a second number of bits for storing a calibration test pattern, wherein the second number of bits is greater than the first number of bits.

International Classification:

G11B 5596

US Classification:

360 7704, 360 7702

Abstract:

The present invention may be embodied in a method, and related apparatus, for determining a repeatable runout (RRO) compensation value set for a track on a disk in a disk drive, wherein the disk drive is initially manufactured and then shipped for installation in a host system. The track comprises a plurality of embedded servo sectors that define a circumferential path having RRO which requires compensation during track following. The method comprises determining a first RRO compensation value set for the track to a first desired learning level by measuring the RRO for the track based on a first predetermined number of disk rotations during the initial manufacturing of the disk drive. Then, after the disk drive is shipped for installation in the host system, determining a second RRO compensation value set for the track to a second desired learning level by measuring the RRO for the track based on at least a second predetermined number of disk rotations, wherein the second predetermined number of disk rotations is greater than the first predetermined number of disk rotations. The learning technique of the invention allows the disk drive to be shipped for installation in a host system with a portion of its tracks having little or no RRO compensation. After shipment, the disk drive may continue to improve the RRO compensation until all of the tracks have been optimally compensated.
