摘要： A disk drive is disclosed comprising a head actuated over a disk comprising a plurality of tracks. The disk drive further comprises a fly height actuator operable to adjust a fly height of the head. A fly height measurement (FHM) is generated for the head, and a fly height error (FHE) is generated as a difference between the FHM and a target fly height. A comb filter is used to generate fly height compensation values in response to the FHE, and a fly height control signal is generated in response to the FHE and the fly height compensation values, wherein the fly height control signal is applied to the fly height actuator.

摘要： In a method of head-disk contact detection in a hard disk drive, a Radio Frequency (RF) carrier signal is injected into a slider which is flying above a surface of a disk in a hard disk drive. A modulated version of the RF carrier signal is received from the slider. The modulated version of the RF carrier signal is demodulated to achieve a demodulated signal. A signal spectrum of a range of frequencies in the demodulated signal is monitored for activity indicative of a contact between a head of the slider and the surface of the disk. An occurrence of the contact is determined based upon an occurrence of the activity.

摘要： A compliant, flexible air bearing slider (ABS) reduces the contact forces between the slider and disk, thereby reducing excessive burnishing and wear and increasing the reliability of the slider. According to an embodiment, an ABS has at least one “compliance-enhancing feature” which reduces the bending mode vibration frequency of the slider. By causing the slider to flex, and bringing the bending mode vibration frequency closer to the pitch 2 eigenmode frequency, coupling of the different vibration modes can be obtained. Thus, the different vibration modes can effectively dampen each other and result in reduced contact forces between the slider and disk.
摘要翻译：兼容柔性的空气轴承滑块（ABS）可减少滑块和圆盘之间的接触力，从而减少过度抛光和磨损，并提高滑块的可靠性。根据实施例，ABS具有至少一个“柔顺增强特征”，其降低了滑块的弯曲模式振动频率。通过使滑块弯曲，并使弯曲模式振动频率更接近于本征模式频率，可以获得不同振动模式的耦合。因此，不同的振动模式可以有效地相互阻尼并且导致滑块和盘之间的接触力减小。

摘要： A method and system for determining localized contact potential voltages and localized clearance data between a slider body and a hard disk of a hard disk drive. In embodiments of the present invention, a plurality of direct current (DC) pulses are applied between said slider body and a discreet location of the hard disk. In embodiments of the present invention, the discreet location of the hard disk comprises a portion of a data track of the hard disk. In embodiments of the present invention, a variation in the clearance of the slider body is determined when a given voltage is applied. Furthermore, a first set of DC pulses has a positive/negative bias while a second set of DC pulses has a negative/positive bias. The voltage of the sets of DC pulses is increased until a contact between the slider body and the hard disk is detected.
