摘要： In accordance with various embodiments, a radial separation distance between first and second servo seams on a storage medium is determined, and a scaled position signal is generated in relation to the determined radial separation distance and a measured position signal. An error runout correction (ERC) value is obtained from the scaled position signal, and the ERC value is thereafter used to compensate for repeated runout (RRO) error.

摘要： A method and system for self-writing track locations of a data disk in a disk drive in order to reduce overall track runout are disclosed. First set of servo bursts are self-written along a track via a transducer, and repeatable runout correction values for the first servo bursts are calculated. Then, second servo bursts are self-written along the track via the transducer such that the first and second servo bursts form a plurality of servo sector patterns that define the track centerline, wherein the second servo bursts are positioned using said correction values to essentially compensate for the runout in the first servo bursts and reduce the overall track runout.

摘要： Apparatus and method for compensating for positional indicia misplacements in the positioning of a control object, such as with servo seam misplacements on a data storage device storage medium. An actual position for the control object is determined in relation to a corrected commanded position of the control object and a corrected position error of the control object. The corrected commanded position is determined in relation to a gain error and an actual commanded position, and the corrected position error determined in relation to the gain error and an actual position error. Preferably, an actual position error of the control object is next determined in relation to the actual position, and the control object is moved to reduce the actual position error. The positional indicia preferably comprise AB and CD seams of ABCD servo dibit patterns on a recording surface.

摘要： A method of reducing microjog errors in a disk drive having a data recording disk with data tracks and a transducer head positionable on the tracks. The head includes a writer element offset from a reader element. To reduce microjog errors, track squeeze is measured at a number of locations across the surface, wherein the squeeze is due to mis-positioning of the track relative to neighboring tracks. A microjog distance for the destination track is provided, and a microjog correction value based on the measured track squeeze is calculated. The correction value is applied to the microjog distance to obtain a corrected microjog distance that reduces microjog errors due to track squeeze.
