伺服写入方法，补偿伺服模式和硬盘驱动器相位失配的方法

Method of servo writing, method of compensating phase mismatch of servo pattern and hard disk drive on which the methods are implemented
Abstract:
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.
Abstract(Chinese):

一种用于分割成多个圆形轨迹的磁记录介质的每个轨道的伺服写入的方法，包括通过根据由磁头和磁道的轨道形成的倾斜角来控制记录电流的相位来执行相位调整操作 记录介质，并且当使用磁头磁化磁记录介质以便具有对应于伺服图案的磁化图案时，写入伺服图案。
