    摘要: Method and system aspects for calibrating an MR offset in an MR head are presented. A method aspect includes identifying an occurrence of a calibration condition to initiate an MR offset check, and performing the MR offset check to ensure an MR offset value has not changed beyond an acceptable tolerance in order to maintain proper servoing of the MR head. A system aspect includes a hard disk for storing data, a read/write MR head for reading and writing data to/from the hard disk, and a control unit. The control unit performs an MR offset calibration of an MR offset value for the read/write MR head in response to a calibration condition occurring in order to ensure maintenance of the MR offset value within an acceptable tolerance for proper servoing of the read/write MR head.
