DISK DRIVE ADAPTIVE RESONANCE COMPENSATION METHOD AND APPARATUS |
摘要 |
A method used in a disk drive system for compensating a frequency component affecting servo control performance. The method includes detecting a frequency component affecting a servo control output in a disk drive/head during a manufacturing process and storing the detected frequency component in a nonvolatile memory device. A frequency component is read from a nonvolatile memory device corresponding to a selected head each time the disk drive is turned on by a user. A parameter value of a filter is determined by using a servo control circuit of the disk drive to suppress the read frequency component.
