Optical To Magnetic Alignment In Magnetic Tape System

View page
US Patent:
6940681, Sep 6, 2005
Filed:
Aug 20, 2001
Appl. No.:
09/933920
Inventors:
George Bellesis - Jefferson MA, US
Leo Guglielmo - Ormond Beach FL, US
Robert Johnson - Acton MA, US
James Fitzpatrick - Sudbury MA, US
Assignee:
Quantum Corporation - San Jose CA
International Classification:
G11B005/584
US Classification:
360 7712, 360 7703, 360 7802
Abstract:
A method of positioning a selected recording channel on a recording head relative to an optical servo system includes positioning the optical servo system at a first position relative to the selected recording, processing an alignment tape to determine a lateral offset between the optical servo system and the selected recording channel and positioning the optical servo system at a second position relative to the selected recording channel using the lateral offset. An alignment tape is also provided, which includes an elongated continuous web of flexible plastic substrate material having two edges and defining a front major surface and a back major surface, a magnetic storage medium formed on the front major surface, an inert medium formed on the back major surface and a track of alignment voids for indicating actual lateral displacement of the selected recording channel relative to the optical servo system.

Optical Sensor To Recording Head Alignment

View page
US Patent:
7023650, Apr 4, 2006
Filed:
Nov 7, 2001
Appl. No.:
10/037083
Inventors:
Vijay K. Basra - Reading MA, US
Leo Guglielmo - Ormond Beach FL, US
George Bellesis - Jefferson MA, US
Assignee:
Quantum Corporation - San Jose CA
International Classification:
G11B 5/584
US Classification:
360 7712, 360122
Abstract:
A technique of positioning a recording head relative to an optical servo system in a magnetic recording tape system read/write assembly is described. The technique includes positioning an optical sensor of the optical servo system at a first position relative to a selected one of recording channels on the recording head and positioning the optical sensor at a second position relative to the selected recording channel using an alignment target on the recording head. A recording head in a read/write assembly of a magnetic recording tape system is also described. The recording head includes recording channels fabricated on a wafer and an alignment target affixed to the wafer between a first read-write element of a recording channel and a second read-write element of the recording channel, the alignment target fabricated to produce an optical reflectance signal.

Demagnetization Of Magnetic Media For Data Storage Device Using Gradually Reduced Magnetic Field

View page
US Patent:
7079345, Jul 18, 2006
Filed:
Jan 17, 2002
Appl. No.:
10/054355
Inventors:
Hai Chi Nguy - San Jose CA, US
Steven Lambert - San Jose CA, US
Steven Marshall - Northboro MA, US
George H. Bellesis - Jefferson MA, US
Assignee:
Maxtor Corporation - Longmont CO
International Classification:
G11B 5/09
US Classification:
360 66, 360 55, 360 62, 335209, 335284, 361267, 361143, 361149, 361159
Abstract:
Demagnetizing magnetic media for recording data in a data storage device includes placing the magnetic media in a magnetic field at a first strength, and gradually reducing the magnetic field to a second strength to essentially eliminate net magnetization in the magnetic media.

Magnetic Servo Of A Recording Head

View page
US Patent:
20030043498, Mar 6, 2003
Filed:
Sep 5, 2001
Appl. No.:
09/946583
Inventors:
Robert Johnson - Acton MA, US
George Bellesis - Jefferson MA, US
International Classification:
G11B005/584
US Classification:
360/077120
Abstract:
A method of aligning a magnetic read/write head to data tracks on a magnetic surface of a digital linear tape. The method includes writing a signal over a track of optical servo marks located on the magnetic surface of the tape with a servo channel writer, generating a position error signal from read back signals obtained from a servo channel reader and positioning the magnetic read/write head in accordance with the position error signal.
