Abstract
A disk drive includes a spindle that defines a spindle rotation axis, and a disk drive base that has a base depression bounded by a first base depression brim. A disk is attached to the spindle, and the disk includes a disk outer peripheral extent. The disk drive includes a disk limiter protrusion extending over an arc of the disk outer peripheral extent that spans no more than 20° about the spindle rotation axis. According to one aspect of the invention, a first radius that extends from the spindle rotation axis over the first base depression brim is angularly disposed no more than 25° from any second radius that extends from the spindle rotation axis to the disk limiter protrusion. According to another aspect of the invention, the disk limiter protrusion may protrude from an edge of a VCM yoke top plate towards the spindle rotation axis.
