摘要： A hard disk drive for a computer has a base containing a stack of rotatable disks and an actuator with a set of arms that is pivotable relative to the disks. At least one magnetic head is mounted to each arm for reading information from or writing information to a respective disk. The drive also has a stationary shock support member or comb located adjacent to the outer edges of the disks and the actuator. The teeth of the comb are interposed with the disks and arms throughout the range of pivotal motion of the arms. The teeth prevent incidental contact between the disks and arms in the event of mechanical shock to the hard disk drive.

摘要： The present invention provides a method and load/unload structure for implementation in a disk drive, whereby debris is prevented from accumulating on the surface of an air bearing slider by moving the slider ABS across a stationary cleaning pad formed integrally with the ramp structure during loading and unloading. As a first aspect of the invention, space at the disk perimeter is used efficiently by providing a stationary cleaning surface integral to the ramp structure. As another aspect of the invention, cleaning may be enhanced by dithering the slider across the stationary pad, e.g., at selected resonant frequencies, to remove a larger volume of debris. As yet another aspect of the invention, baffling may be provided in the disk drive interior to channel the airflow generated by the disk such that it is directed over the cleaning pad in the direction of an air filter.

摘要： An arrangement for reducing the stiction bond at power-up time between an slider parked on a disk or other magnetic recording medium. A thermally expansive medium such as alumina is included in the slider body thermally adjacent to the write element. At power-up time or when a failure of the disk, etc. to rotate is detected during startup, a current is applied to the write element. The volume expansion resulting from the heat causes a change in the shape and/or location of the slider surface in contact with the disk and thereby breaks or reduces the slider/disk stiction bond.

摘要： A method and apparatus for predicting write failure resulting from flying height modulation and initiating re-writing of data upon occurrence of the predicted write failure is disclosed. According to the present invention, if the slider or transducer flying height modulates during the write process, such modulation is detected, and a rewrite of the same data is forced. A write reassign may be initiated when a thermal signal exceeding the predetermined threshold is detected during the rewrite and/or a read/verify may be initiated after the rewrite.

摘要： An apparatus and method for utilizing an off-center gimbal to increase head to disk interface reliability for contact recording systems. The method provides a suspension for reaching over a disk. A slider having a read/write head element on a trailing edge (TE) portion is also provided, the slider coupled with the suspension. In addition, an off-center gimbal device is coupled with the slider and the suspension away from the center of the slider and closer to the TE portion of the slider such that when the TE portion of the slider contacts a disk a bouncing motion of the TE with respect to the disk is reduced.

摘要： A disk drive with switchable power levels for the heaters in the sliders is disclosed. The invention includes a switch for the electrical circuit of each heater which selects between two or more voltages to apply to the power control element and the heater with at least a high and a low voltage option. The heater power control circuit dissipates a certain amount of heat as a part of the control process. By having a low voltage option the disk drive can save power and reduce the amount of heat dissipated by the heater control circuit when high power is not required. The programmable switch is controlled by the drive control system. The high power setting can be used during manufacturing testing or otherwise if higher heater power is needed. The low power setting is used for normal operation or to save power.
