Method of servo writing, method of compensating phase mismatch of servo pattern and hard disk drive on which the methods are implemented |
摘要 |
A method of servo writing for each track of a magnetic recording medium divided into a plurality of circular tracks including performing a phase adjustment operation by controlling a phase of a recording current according to a skew angle formed by a magnetic head and a track of the magnetic recording medium, and writing a servo pattern when the magnetic recording medium is magnetized using a magnetic head so as to have a magnetized pattern corresponding to a servo pattern.
