20090059432 | HEAD SLIDER OF MAGNETIC DISK DEVICE - Lubricant on a rotating recording medium can attach to a slider, particularly on the pad formed in the proximity of the trailing edge. In the slider of this invention, lubricant is not accumulated in the vicinity of the trailing edge and can be drawn to the trailing edge and dispersed constantly. The head slider includes a center pad formed on an air bearing surface in the vicinity of the center of a trailing edge of the slider. A trailing pad is formed so as to bridge a trailing edge of the center pad and the trailing edge of the slider. The trailing pad is formed lower than a highest surface of the center pad and higher than a lowest surface of the slider. | 03-05-2009 |
20100002341 | MAGNETIC HEAD SLIDER AND MAGNETIC DISK APPARATUS - A magnetic disk apparatus includes a magnetic recording medium that records information, a magnetic head slider flying over a surface of the magnetic recording medium to read or write information from or to the magnetic recording medium, a rear rail having a rear ABS and a rear stepped bearing surface on an air outflow side from which air flows out from the magnetic head slider, the rear stepped bearing surface being deeper than the rear ABS, and at least one closed vibration attenuation groove that is formed on the rear ABS of the rear rail with a depth greater than the rear ABS and has the rear stepped bearing surface on an air inflow side. | 01-07-2010 |
20100053816 | HEAD-SLIDER, HEAD-ARM ASSEMBLY INCLUDING THE HEAD-SLIDER, AND HARD-DISK DRIVE INCLUDING THE HEAD-ARM ASSEMBLY INCLUDING THE HEAD-SLIDER - A head-slider which is configured to fly above a magnetic-recording disk. The head-slider includes a disk-facing side, which faces the magnetic-recording disk. The disk-facing side includes a plurality of surfaces including at least: a step bearing surface; a rail surface, which protrudes toward the magnetic-recording disk and is configured to exert a positive pressure; a deep-recessed surface, which is formed deeper than the step bearing surface and is configured to exert a negative pressure; an extended lateral surface, which is formed at substantially a same depth as the step bearing surface and disposed outside the deep-recessed surface in a width direction of the head-slider; and, an extended rear surface, which is formed at substantially the same depth as the step bearing surface and disposed at a trailing edge of the head-slider, and contiguous with the extended lateral surface. | 03-04-2010 |
20100271733 | HARD DISK DRIVE - A hard disk drive includes an end tap which extends from an end part of a suspension and supports a slider; a ramp which includes a parking guide rail including a parking guide wall on which the end tap is contact-guided and parked when a disk stops rotating; and a ramp rotating unit which is connected to the ramp and rotates the ramp based on parking states of the end tap. | 10-28-2010 |
20110026164 | AIR BEARING SURFACE OF A HEAD SLIDER IN A HARD DISK DRIVE - A head slider for supporting a head over a magnetic disk in a hard disk drive, and a method of making the head slider are disclosed. The air bearing surface (ABS) of the head slider includes a relatively deep recess in front of a trailing pad and an island pad. A recess is formed between the trailing pad and the island pad of the ABS. In operation, the recess may reduce the peak pressure of the ABS, resulting in a reduced mid disk (MD) hump without a reduction in other performance parameters. The reduction in peak pressure may also reduce lubrication pick-up from the magnetic disk. | 02-03-2011 |
20140192440 | SLIDER WITH SHOCK DAMPING FEATURES - An apparatus and associated methodology contemplating a slider body defining longitudinal extents at a leading end and a trailing end. A fluid bearing surface is formed in part by a side rail extending substantially longitudinally along the slider body and joined to a cross rail extending substantially laterally along the slider body. The side rail and the cross rail define at least a portion of a positive pressure recess. A vent is defined in the fluid bearing surface that is in fluid communication with ambient pressure fluid on one side of the side rail but is not in fluid communication with the positive pressure recess on the other side of the side rail. | 07-10-2014 |
