    摘要： A hard disk drive with a disk that contains a target track and an adjacent track. The drive includes a circuit that determines an error in data read from the target track. Data from the adjacent track is stored in memory. The adjacent track is then erased and the target track data is re-read from the target track. Erasing the adjacent track allows the target track data to be read without adjacent track interference. The data from the adjacent track is typically rewritten onto the disk from memory so no data is lost.
