摘要：
A disk drive is disclosed which pre-computes first seek parameters to seek to a continuation track storing read-ahead data, and second seek parameters to seek to a target track of a next command. An abort window is also computed for aborting a read-ahead operation early in order to seek to the target track of the next command. If the head enters the abort window, the disk drive is programmed with the second seek parameters to seek to the target track of the next command. If the read-ahead operation requires a seek to the continuation track prior to the head entering the abort window, the disk drive is programmed with the first seek parameters to seek to the continuation track.
