Filed:

Jan 17, 2002

Appl. No.:

10/052621

Inventors:

Gang Herbert Lin - San Jose CA
Thao Nguyen - San Jose CA

Assignee:

Maxtor Corporation - Longmont CO

International Classification:

G11B 566

US Classification:

428 653, 428 657, 428156, 428212, 428215, 428336, 428409, 428694 T, 428694 TS, 428694 TM, 428694 B, 428694 BS, 428694 BM

Abstract:

The present invention is directed to a writable or recordable disk that has radially varying recording properties. In one configuration, the magnetic moment, magnetic remanence, and/or information layer thickness decreases from the disk inner diameter to the disk outer diameter. In one configuration, the writing property or coercivity of the disk decreases from the disk inner diameter to the disk outer diameter. The variation in writing property may be accomplished by varying the thickness of an underlayer to the information layer.

International Classification:

G11B 27/36
G11B 5/03

US Classification:

360 31, 360 66

Abstract:

A method of determining side track erasure in a disk drive having a disk and a transducer. A target track and one or more side tracks proximate to the target track on the disk are selected, and recording parameters for recording signals on the target track and each side track with the transducer are selected. Thereafter, signals are recorded on each side track and then signals are recorded on the target track multiple times. A reduction in the integrity of the recorded signals on each side track due to recording signals on the target track multiple times is detected, and the detected reduction in the integrity of the recorded signals on each side track represents the amount of the erasure of the recorded signals on the side track. Recording parameters are changed based on the signal integrity reduction to minimize side track erasure.

International Classification:

G06F 12/16

US Classification:

711162, 707204

Abstract:

Various embodiments of systems and methods for performing volume-based incremental backups are disclosed. A method may involve generating a snappoint of a volume. The snappoint indicates which portions (e. g. , blocks or extents) of the volume have been modified between a time at which the snappoint was generated and a time at which a subsequent snappoint was generated. The method may also involve accessing information mapping the file to the volume and, if the snappoint identifies as having been modified any blocks of the volume to which the file maps, copying those blocks from the subsequent snappoint to the backup device. Portions not identified as having been modified by the snappoint are not copied. Program instructions implementing such a method may be stored on a computer accessible medium.

Inventors:

Erhard T. Schreck - San Jose CA, US
Gang Herbert Lin - San Jose CA, US

International Classification:

G11B 5/127

US Classification:

3601253

Abstract:

A disk drive having a head with a recessed write pole for perpendicular recording to a disk. The head also includes a read element, a first shield and a second shield that share a common plane, and the write pole is recessed relative to the plane, thereby reducing pole tip protrusion.

Gang Herbert Lin - San Jose CA, US

Assignee:

Seagate Technology LLC - Scotts Valley CA

International Classification:

G11B 5/147

US Classification:

36012508

Abstract:

A magnetic head for perpendicular recording includes a main pole having a first end and a second end. Coils are positioned with respect to the main pole. A return pole forms first and second return paths for magnetic flux extending from the second end of the main pole. The main pole includes an anti-ferromagnetic layer to pin a remnant magnetic moment in the horizontal direction.
