摘要： A method for selectively sensing and removing asperities from the surface of hard disk drive media is disclosed. A thermally controlled flying height burnish slider is flown on a test stand with its thermal flying height control deactivated. The burnish slider flies at a nominal flying height over the surface of the media to remove any existing loose particles from the surface. A glide slider coupled to a PZT sensor is then flown over the surface of the media, the PZT sensor head mapping locations of any asperities on the surface of the media. The thermal flying height controlled burnish slider is next flown over the surface of the media with the thermal flying height control activated. The thermal flying height control is actuated when a mapped location of an asperity on the surface is proximate to the burnish slider, causing the burnish slider to protrude, wearing off the asperity.

摘要： A glide-height disk-tester operates with the test disk rotating at a predetermined constant rotational speed and uses a glide head with an electrically-resistive heater and a thermally-responsive protrusion pad located on its trailing end. The linear velocity of the disk relative to the slider maintains the slider at its nominal fly height, which is typically higher than any expected asperity. With no current applied to the heater, the protrusion pad is generally flush with the air-bearing surface of the slider. Increasing levels of current are applied to the heater, which causes movement of the protrusion pad toward the disk surface. When the pad contacts an asperity, the current level applied at the instant of asperity contact is recorded. The applied current level can be correlated to the glide height from a previous calibration process using a calibration disk with known calibration bump heights.

摘要： Embodiments of the invention improve the power consumption and response speed of a heater for the gap flying height (hg) adjustment, to minimize an influence that the heater has on a life of a read element, and to provide a heater having resistance lines reduced in breaking and ensuring higher reliability. In one embodiment, a read/write element is formed near an air bearing surface (ABS) on a slider, and the circumference of the read/write element is filled with alumina. The read/write element includes an upper magnetic pole piece, a lower magnetic pole piece, a coil, and a resist filling around the coil, and a read element (MR) for performing reading, and an upper shield and lower shield for protecting the read element from an external magnetic field. A heater for adjusting the flying height is provided between the slider and the read/write element but near the read/write element. A temperature gradient relaxing material having a thermal conductivity higher than that of the heater and that of a material (alumina) filling around the heater is formed near the heater.

摘要： Embodiments of the present invention provide a process that monitors a magnetic playback signal while gradually increasing an electricity supply amount for a heater to thereby determine contact between a magnetic head slider and a magnetic disk medium. According to one embodiment, after components for configuring a magnetic recording/playback portion are assembled into a housing, magnetic information is played back on a specific track of a magnetic disk medium by using a playback element while gradually increasing an electricity supply amount for a heater of a magnetic head slider. An amplitude of a playback signal is measured at a plurality of portions along a circumferential direction of the track. Contact between the magnetic head slider and the magnetic disk medium is detected in accordance with an increase in variation in the measured amplitude. Then, a value obtained by subtracting an predetermined value of an electricity amount from an electricity amount in the event of detection of the contact is stored (set) as an appropriate electricity amount for the magnetic head slider into a storage portion.
