10/280881
Inventors:

Hai Chi Nguy - San Jose CA, US
Michael Mallary - Sterling MA, US
Adam F. Torabi - Shrewsbury MA, US
Bruce Lairson - Los Altos CA, US
Assignee:

Maxtor Corporation - Longmont CO
International Classification:

G11B005/23
G11B005/187
US Classification:

360119, 360125
Abstract:

Longitudinal Media With Soft Underlayer And Perpendicular Write Head
view source
US Patent:

7149045, Dec 12, 2006
Filed:

Oct 30, 2003
Appl. No.:

10/697075
Inventors:

Michael L. Mallary - Sterling MA, US
Steven Marshall - Northboro MA, US
Mourad Benakli - Shrewsbury MA, US
Adam F. Torabi - Shrewsbury MA, US
Assignee:

Maxtor Corporation - Scotts Valley CA
International Classification:

G11B 5/09
G11B 5/66
G11B 5/667
US Classification:

360 55, 428826, 428828, 4288321, 4288323
Abstract:

A magnetic recording device including a longitudinal magnetic recording medium. The longitudinal magnetic recording medium includes a magnetically soft underlayer disposed under a longitudinal recording layer. A perpendicular write head is utilized to write data to the longitudinal magnetic recording medium wherein the longitudinal recording layer is disposed within an effective write gap formed by the perpendicular write head and the underlayer. The longitudinal component of the perpendicular write head is sufficient to switch the magnetic grains in the recording layer in the presence of the perpendicular field. The magnetic recording medium can have a high areal density and improved magnetic properties.

Increasing Areal Density In Magnetic Recording Media
view source
US Patent:

7161755, Jan 9, 2007
Filed:

Apr 7, 2003
Appl. No.:

10/408650
Inventors:

Mourad Benakli - Shrewsbury MA, US
Michael Mallary - Sterling MA, US
Adam F. Torabi - Shrewsbury MA, US
Assignee:

Maxtor Corporation - Longmont CO
International Classification:

G11B 5/02
US Classification:

360 55
Abstract:

A magnetic recording medium is made of a thin film medium that includes magnetic grains. At least one of a magnetization density of the magnetic grains, a crystalline anisotropy field of the magnetic grains, a thickness of the recording medium, an average diameter of the magnetic grains, and a surface packing fraction of the recording medium are selected so that resulting magneto-static fields both decrease thermal switching of individual magnetic grains and enhance collective switching of a group of magnetic grains in response to a switching magnetic field.

Tapered Write Pole For Reduced Skew Effect
view source
US Patent:

7430095, Sep 30, 2008
Filed:

Apr 11, 2007
Appl. No.:

11/786266
Inventors:

Mourad Benakli - Shrewsbury MA, US
Michael Mallary - Sterling MA, US
Adam F. Torabi - Shrewsbury MA, US
Assignee:

Maxtor Corporation - Scotts Valley CA
International Classification:

G11B 5/127
US Classification:

36012515, 2960318, 2960307
Abstract:

A write pole for a read/write head of a disk drive system has a tapered surface on a leading edge thereof. Preferably, the tapered surface has a taper angle of between 0 and 20 degrees from a plane normal to the ABS. By having a write pole with a taper in this manner, sufficient write fields can be achieved even with thinner write pole tips on the ABS surface. By decreasing the thickness of the write pole tip in this manner while maintaining sufficiently high write fields, the skew profile of a write head can be decreased and areal density increased.

International Classification:

G11B 5/127
US Classification:

36012574
Abstract:

Western Digital (Fremont), LLC - Fremont CA
International Classification:

G11B 11/00
US Classification:

369 1333, 36911227
Abstract:

An energy assisted magnetic recording (EAMR) transducer coupled with a laser is described. The EAMR transducer has an air-bearing surface (ABS) residing near a media during use. The EAMR transducer includes optical and writer modules. The optical module includes a waveguide and a near field transducer (NFT). The waveguide directs the energy from the laser toward the ABS. The NFT focuses the energy onto the media. The optical and writer modules are physically separate such that no portion of the waveguide is interleaved with a magnetic portion of the writer module. The writer module includes a write pole and coil(s). The write pole includes a pole-tip portion for providing a magnetic field to the media and a yoke. The pole-tip portion has an ABS-facing surface, a sloped surface, and a NFT-facing surface therebetween.
