Abstract:
1. A method to support repairable servowriting, comprising: calculating a first set of wedge offset reduction field (WORF) and/or position error signal (PES) information for one or more servo tracks on a surface of a rotating medium; comparing the first set of WORF and/or PES information for the one or more servo tracks with a pre-detennined threshold; repairing a servo burst and/or a boundary of the servo burst on the one or more servo tracks via a read and/or write element of a read/write head if the WORF and/or PES information exceeds the threshold, the repairing including calculating a second set of WORF and/or PES information for the one or more servo tracks; and storing the second set of WORF and/or PES information for retrieval during servowriting.
