Hard Disk Drive Head-Media System Having Reduced Stiction And Low Fly Height
US Patent:
6683754, Jan 27, 2004
Filed:
May 17, 2002
Appl. No.:
10/150373
Inventors:
Shoji Suzuki - San Jose CA
Ta-Chang Fu - San Jose CA
Ta-Chang Fu - San Jose CA
Assignee:
Komag, Inc. - San Jose CA
International Classification:
G11B 560
US Classification:
3602355, 360 9701, 360135, 3602358, 3602366
Abstract:
A head and disk system for use in a disk drive that includes a slider having a surface that contacts the disk. This disk contacting surface of the slider is textured with pads, bumps, an etched surface or an otherwise roughened surface. The contact area of the disk has a greater roughness than a data zone. The head disk system exhibits acceptable stiction. Additionally, low glide avalanche over the CSS zone, thus enabling low fly height, is achieved.
Glass Substrates And Methods Of Annealing The Same
US Patent:
8206789, Jun 26, 2012
Filed:
Nov 3, 2009
Appl. No.:
12/611827
Inventors:
Shoji Suzuki - San Jose CA, US
Assignee:
WD Media, Inc. - San Jose CA
International Classification:
B32B 3/02, B05D 1/12, G11B 5/82
US Classification:
427355, 427180, 4288469, 4288488, 65111
Abstract:
A method for forming a glass substrate comprises the steps of forming a glass blank with opposing substantially planar surfaces and at least one edge, coating the glass blank in silica-alumina nanoparticles, the silica-alumina nanoparticles comprising an inner core of silica with an outer shell of alumina, annealing the coated glass blank to form a conformal coating of silica-alumina around the glass blank, and polishing the coated glass blank to remove the conformal coating of silica-alumina from the opposing substantially planar surfaces thereof.
Hard Disk Drive With Load/Unload Capability
US Patent:
2002006, May 23, 2002
Filed:
Sep 21, 1999
Appl. No.:
09/399935
Inventors:
SHOJI SUZUKI - SAN JOSE CA, US
International Classification:
G11B005/54
US Classification:
360/254700
Abstract:
A disk drive having a mechanism for securing a suspension arm adjacent to the inner diameter region of a disk is described. The securing mechanism engages the suspension arm adjacent the inner diameter region of the disk during load/unload operations. The securing mechanism may be mounted in the drive chassis underneath a subsequently mounted disk. Prior to the mounting of the securing mechanism, a suspension arm may be mounted into the chassis. The securing mechanism is stacked on top of the chassis to engage the suspension arm without the need for lateral adjustment of the suspension arm. The disk may then be mounted into the chassis with the suspension arm pre-unloaded on the securing mechanism.
Magnetic Head For Proximity Recording
US Patent:
7006323, Feb 28, 2006
Filed:
Jul 18, 2003
Appl. No.:
10/623025
Inventors:
Shoji Suzuki - San Jose CA, US
Assignee:
Komag, Inc. - San Jose CA
International Classification:
G11B 5/60, G11B 21/21
US Classification:
360 75, 3602371
Abstract:
A slider having a protrusion extending beyond an air bearing surface of the slider to maintain the slider with a positive pitch angle during contact with the surface of a disk. The protrusion may be disposed on a leading edge step of the slider body with the protrusion extending beyond the air bearing surface. The slider may be used in a load/unload disk drive system to provide a positive pitch attitude to the slider at all times during operations of the disk drive system.

International Classification:
B24B 5/00
US Classification:
451285, 287286, 287398
Abstract:
A carrier has openings for holding workpieces during polishing. Upper and lower polishing pads push against upper and lower surfaces of the workpieces, respectively. A ring is provided within the openings. This ring surrounds the workpieces, and prevents or reduces roll-off.
Magnetic Recording Disk Having A Transition Zone
US Patent:
2007007, Mar 29, 2007
Filed:
Nov 28, 2006
Appl. No.:
11/605906
Inventors:
Shoji Suzuki - San Jose CA, US
International Classification:
G11B 5/82, G11B 5/37, G11B 5/33
US Classification:
360135000, 360112000, 360313000
Abstract:
A disk drive having a magnetic recording disk with a transition zone is described. A surface texture of the transition zone induces the head to fly at a greater height than when operating over a data zone, while transitioning the head to a landing zone to park.
Methods For Improving The Strength Of Glass Substrates

US Classification:
427131, 4273761, 4273744, 4273746, 4273745
Abstract:
Methods for improving the strength of glass substrates are described. One such method for strengthening a glass disk substrate for a storage device includes immersing at least a portion of the glass substrate in a solution, the solution including a solvent and a coating material selected from the group consisting of NaOH, KOH, and KNO, removing the glass substrate from the solution, allowing the solvent to evaporate from the glass substrate, and heating the glass substrate at a preselected temperature for a preselected duration, where the preselected temperature is sufficient to substantially melt the coating material and is less than a transition temperature of the glass substrate.

Assignee:
Komag, Inc. - San Jose CA
International Classification:
B05D 300
US Classification:
427555
Abstract:
A method in accordance with our invention for providing texture bumps on a substrate comprises the step of forming elliptical ridge-shaped bumps on the substrate. In one embodiment, substrate is used in the manufacture of a magnetic disk used in a disk drive. The elliptical bumps cause less vibration of the read-write head than circular bumps. The elliptical bumps also provide reduced friction between the disk and a read-write head during use.
Banded Lzt Css Zone
US Patent:
7301726, Nov 27, 2007
Filed:
Nov 4, 2004
Appl. No.:
10/982094
Inventors:
Shoji Suzuki - San Jose CA, US
Assignee:
Komag, Inc. - San Jose CA
International Classification:
G11B 17/00, G11B 5/012
US Classification:
360 9701, 360 9702, 360 9703, 360 9704
Abstract:
A magnetic recording disk having a non laser zone texturing (LZT) band in the contact-start-stop (CSS) zone. The width of the non-LZT band in the CSS zone may be greater than the width of a read and/or write element of a head and less than the width of a center pad on the head in order to prevent contact between the read and/or write element and the CSS zone's textured surface. The width of the non-LZT band may also be designed to account for head skew angle and positioning error due to movement of a suspension arm supporting the head.
