摘要： A servo burst signal recording method using an enhanced pattern and a disk recording medium are provided. The disk recording medium having at least two servo burst regions on which servo burst signals are recorded in the diametrical direction on tracks of the disk recording medium, the servo burst regions each being divided into at least two sub-regions in a traveling direction of a head, one sub-region having the same width as that of a track, and the other sub-region having a smaller width than that of the track. The disk recording medium enables the user to obtain a servo burst signal component without having a dead zone even in the case when the width of a reading head is smaller than that of the recording head, which enhances the accuracy of the tracking control.

摘要： A magnetic head parking system of a hard disk drive to move a magnetic head mounted on a slider of an actuator from a data zone of a disk and to place the magnetic head in a parking zone thereof when the disk stops rotating. The magnetic head parking system includes a head limiter provided on an upper surface of a flange of a spindle motor to protrude toward the disk and restricting a range of movement in upward and downward directions of the magnetic head placed in the parking zone of the disk. The head limiter is provided at a position opposite to a position where the slider of the actuator is installed or at a position deviating from and/or adjacent to a position directly under the slider. Thus, when an external impact is applied and an operation of the hard disk drive is stopped, the range of the up and down movement of the magnetic head is limited by the head limiter, so that the possibility of the damage to the magnetic head due to the head slap can be lowered.

摘要： Provided are a method of protecting a head and a disk in a HDD from shocks and an apparatus therefor by detecting the movement of the HDD using the amount of jitter in servo signals and unloading the head when the movement is great enough to damage the head and the disk. The method of protecting the HDD from shocks includes: reading the servo signals from the rotating disk using the head that follows tracks on the disk, detecting an amount of jitter in the servo signals, comparing the detected amount of jitter with a predetermined threshold amount of jitter corresponding to a movement great enough to damage the head and the disk, and unloading the head if the detected amount of jitter is greater than the predetermined threshold amount of jitter.
