    摘要: A method and apparatus for controlling lubrication in hard disk drives. Hard disk drives often include lubrication on the disks to protect the disks from incidental contact with the head slider. Embodiments of the invention include lubrication control surfaces or dams on the air bearing surface (ABS) of the head slider. The dams redirect air flow on the ABS and/or redirects excess lubrication that migrates from the disk to the head slider. By redirecting excess lubrication, the lubrication control dams remove and/or store the lubrication and avoid failure that may occur as a result of the lubrication interfering with the ABS or the read/write elements of the head.

    摘要: A method of forming a sheet wafer 1) passes at least two filaments through a molten material to produce a partially formed sheet wafer, 2) directs a cooling fluid at a flow rate toward the partially formed sheet wafer to convectively cool a given portion of the partially formed sheet wafer, and 3) monitors the thickness of the given portion of the partially formed sheet wafer. To ensure appropriate thicknesses of the wafer, the method controls the flow rate of the cooling fluid as a function of the thickness of the given portion of the partially formed sheet wafer.

    摘要: Approaches for a head slider for use within a hard-disk drive. The head slider comprises an air bearing surface (ABS) and an electromagnetic transducer disposed at an air outflow end of the air bearing surface. The air bearing surface comprises a slit feature that is present prior to the electromagnetic transducer in the direction of air flow. The physical dimensions of the slit feature are designed to lower an amount of pressure required for a protrusion of the head slider to detect a surface of a magnetic-recording disk. The air bearing surface may further comprise an optional hollow recess prior to the slit feature in the direction of air flow. The size and the shape of the hollow recess are designed to decrease a change in a fly height of the head slider in response to a change in altitude of the hard-disk drive.

    摘要: A method for reducing the range in resistivities of semiconductor crystalline sheets produced in a multi-lane growth furnace. A furnace for growing crystalline sheets is provided that includes a crucible with a material introduction region and a crystal growth region including a plurality of crystal sheet growth lanes. The crucible is configured to produce a generally one directional flow of material from the material introduction region toward the crystal sheet growth lane farthest from the material introduction region. Silicon doped with both a p-type dopant and an n-type dopant in greater than trace amounts is introduced into the material introduction region. The doped silicon forms a molten substance in the crucible called a melt. Crystalline sheets are formed from the melt at each growth lane in the crystal growth region. Co-doping the silicon feedstock can reduce the variation in resistivities among the crystalline sheets formed in each lane.

    摘要: A slider for use with disk drive data storage devices includes a topography that defines features of the slider. The features facilitate in controlling peak pressure, providing stiffness, and/or inhibiting lubricant accumulation on the slider. For example, the features include an air bearing surface and a cavity disposed in front of the air bearing surface. The cavity is closed on all sides by sidewalls.

    摘要: A slider for use with disk drive data storage devices includes a topography that defines features of the slider. The features facilitate in controlling fly-height and/or inhibiting lubricant accumulation on the slider. For example, a trailing air bearing surface of the slider may be formed around a multi-stepped channel that adjusts the fly-height. Further, a shallow shelf behind an air bearing surface and/or curved edges of the features to alter stagnation may contribute to at least inhibiting lubricant collection on the slider.
