Soft error recovery system and method |
摘要 |
A method for reducing errors in data read from a disk drive comprises the steps of: determining errors in data read from a transducer in the disk drive; correcting the errors in data through the use of error correction circuitry; maintaining a metric of the errors in data that are read from the transducer; and when the metric reaches a threshold value, applying a toggle procedure to the transducer in an attempt to improve the transducer's performance. The method further contemplates periodically applying a toggle procedure to the transducer in an attempt to reduce the errors in data, in addition to the application of a toggle procedure when the threshold value is reached.
