摘要： According to one embodiment, a disk drive includes a heating element which is provided on a head and generates heat when supplied with power, thereby to adjust a dynamic flying height of the head. A head-movement detecting unit detects the abnormal movement of the head, a value of which is larger than a preset movement value during a head positioning control. In this case, a heating-element controller stops supplying power to the heating element.

摘要： A slider structure that allows a grounded heater element to be employed, while also allowing a decision of whether the slider is to be an “up” slider or a “down” slider to be made in a late stage in the formation of the slider. The slider includes electrical contact pads for making electrical connection with the heater element. The slider also includes a dedicated ground path formed on the slider body at a location that is removed from either of the first and second contact pads, ground path providing electrical connectivity to the slider body. At a late stage in the manufacture of the read and write head, a determination can be made as to which contact pad is to be a ground pad, and that pad can be electrically connected with the ground path.

摘要： A method for neutralizing the flying height sensitivity associated with thermal pole-tip protrusion (T-PTP) of an air bearing slider comprises creating head material data and air bearing surface (ABS) compensation data, based on which a head/ABS design is created. The head material data comprises at least one material property that is dependent on the manner in which the material is fabricated, such as the coefficient of thermal expansion of a material deposited using a certain deposition process. The ABS compensation data comprises data about how respective ABS features affect air bearing pressure and, therefore, ABS compensation. A protrusion profile is determined for the head/ABS design, and whether or not this protrusion profile meets particular design criteria is then determined. The head/ABS creating and determining process can be iterated if necessary to arrive at a head/ABS design which provides neutral flying height sensitivity to a range of operational temperatures.

摘要： A method for improving the magnetic performance of at least one magnetic transducer operating within a hard disk drive. The method comprises flying the magnetic transducer at a distance of separation from a magnetic recording media. The magnetic transducer is coupled with a highly damped air bearing surface and a fly height control device. At least one operating parameter of the hard disk drive is measured. The magnetic transducer is moved with the fly height control device into contact with the magnetic recording media, in accordance with at least one operating parameter of the hard disk drive. The magnetic transducer is operated while the magnetic transducer is in contact with the magnetic recording media, thereby improving the magnetic performance of the magnetic transducer.

摘要： A magnetic head drive device drives a heater element for controlling a protrusion amount of the magnetic head. The heater drive circuit of the heater element of the magnetic head, in which a read element, a write element and a heat element is included, is constructed by the PWM modulation method. A pair of heater wiring lines is made of a path in which the signal polarity is inverted. Therefore cross-talk noise, to the read wiring line, can be decreased even if PWM driving is executed.
