Abstract
A controller for a disk drive measures track misregistration, extracts non-repeatable runout from measured track misregistration, determines one or more components of non-repeatable runout at various radial locations of a disk, and compares the determined components to known values at different altitudes to determine an operating altitude of a disk drive.
