Method of writing a reference servo signal of hard disk drive and apparatus suitable therefor
摘要：
In a method of writing a reference servo signal of a hard disk drive having a spiral reference servo signal that is referred to when writing a final servo signal is written while a head is moved across a disk for a predetermined time at a target movement velocity, an actual movement velocity of the head is detected from a counter electromotive force generated in a voice coil motor that moves that head, for the predetermined time during which the spiral reference servo signal is written, and the head is controlled to maintain the target movement velocity by feeding back the detected actual movement velocity.
