摘要： Real time monitoring inconsistent operations in a hard disk drive, wherein the hard disk drive comprises a magnetic disk, a controller and a channel clock. A timing signal from the channel clock is measured in real time in the controller. Time intervals between sector identifier marks of the magnetic disk are detected using the timing signal from the channel clock during reading and writing operations of the hard disk drive in the controller. An inconsistency in the drive operations is detected in the controller based on changes in the time intervals between the sector identifier marks is detected during operation of the hard disk drive. The detection of the inconsistency in the drive operations is responded to.

摘要： In a feedback control mechanism for active damping of slider air bearing vibrations in a hard disk drive slider, an assembly is used to acquire a velocity signal from the slider. A filter, electrically coupled with the assembly, is used to filter a velocity signal to achieve a vibration signal. A phase-shifter, electrically coupled with the filter, shifts the phase of the vibration signal to achieve a phase-shifted vibration signal. An amplifier, electrically coupled with the phase-shifter, adjusts the amplitude of the phase-shifted vibration signal to achieve an amplitude adjusted vibration signal. An electrical coupler couples the amplitude adjusted vibration signal with the slider for actively damping air bearing vibrations in the slider.

摘要： In a method of pre-contact detection and active damping of air bearing vibrations in a hard disk drive, a slider is isolated from ground. The slider is then capacitively coupled with a hard disk of the hard disk drive via a thermal fly-height control (TFC) heating element. An alternating current (AC) signal is applied to the slider via the TFC heating element to control the amplitude of the slider.

摘要： A hard disk drive (HDD) including a first resistive temperature detector (RTD) configured to detect a temperature generated by proximity of a slider and a media. The first RTD is proximate an air bearing surface (ABS) of the slider. The HDD also includes a second RTD configured to detect at least one temperature correlated to a fly-height of the slider. The second RTD is not required to be proximate the ABS of the slider. HDD also includes a read/write integrated circuit (IC) configured to determine the fly-height of the slider based on detection of temperatures by the first RTD and the second RTD.
