摘要： One way to minimize full DC head-skew re-calibrations rendered necessary by changes in storage media drive operating temperature is to compensate for temperature-induced DC head-skew using a known relationship between temperature-induced DC head-skew and storage media operating temperature. More specifically, a first DC head-skew is measured at a first arbitrary temperature of the storage media drive. A second DC head-skew is measured at a second arbitrary temperature of the storage media drive. A DC head-skew correction factor is calculated using the first and second DC head-skews at the first and second arbitrary temperatures. When a multi-head storage media drive is powered-up for operation, a temperature sensor located in the storage media drive assembly measures the current storage media drive temperature. The head-skew correction factor is applied based on the measured temperature to correct the DC head-skew.
