Abstract:
1. A method for aligning a data axis of one or more circular data-bearing tracks on an annular surface region of a magnetic media-bearing disk, with a spin axis of a spindle of a disk spin assembly, wherein said data axis is perpendicular to said surface region of said disk and said tracks are concentric with respect to said data axis, wherein said disk has a circumferential edge (CE), comprising the successive steps of: A. supporting said disk on a disk-support surface of said spindle, B. spinning said disk-support surface of said spindle together with said supported disk about said spin axis, C. detecting data on said tracks and in response to detected data identifying: D. rotating said spindle to an alignment position whereby said point FP is aligned with a translation axis extending perpendicular to and intersecting with said spin axis, and between said spin axis and a first portion of said CE along a translation axis, and E. at said alignment position, applying a translation force along said translation axis and toward said spin axis, to said first portion of said CE, whereby said disk is translated along said translation axis to reduce offset of said data axis with respect to said spin axis.
