Method For Magneto-Resistive Head Electrostatic Popping Detection

US Patent:
6556006, Apr 29, 2003
Filed:
Nov 21, 2001
Appl. No.:
09/990631
Inventors:
Zhaohui Li - Santa Clara CA
Andrew Kao - Freemont CA
Keung Youn Cho - San Jose CA
Assignee:
Samsung Electronics Co., Ltd.
International Classification:
G01R 3312
US Classification:
324210, 360 31
Abstract:
A method and system for detecting electrostatic noise in a magneto-resistive head which may be caused by a plurality of conditions manifesting in the frequency domain as either an amplitude spike or an unstable baseline. In one embodiment, the signals generated by the head when reading a DC-erased track are compared. When viewed in the frequency domain the spectrum gap between the signals is used to determine if the head being tested suffers from defects causing an unstable baseline or from defects causing an amplitude spike.

Method And Apparatus To Distinguish Effects Of Adjacent Track Encroachment From Head Thermal Movement

US Patent:
6791775, Sep 14, 2004
Filed:
Oct 15, 2001
Appl. No.:
09/981464
Inventors:
Zhaohui Li - Santa Clara CA
Geng Wang - San Jose CA
Keung Youn Cho - San Jose CA
Assignee:
Samsung Electronics, Co., Inc.
International Classification:
G11B 2736
US Classification:
360 31, 360 53, 360 66
Abstract:
The present invention is a method and system to determine a quality of a head in a hard disk drive. The method comprises providing a disk having a at least one side with a plurality of tracks, writing on a predetermined track on the plurality of tracks and reading a profile of the predetermined track to provide a first profile value. The head is then moved to an adjacent track where it writes on the adjacent track. A profile of the predetermined track is then read to provide a second profile value. A quality of the head can then be determined based on the first and second values.

Novel Method To Detect Junction Induced Signal Instability From Gmr/Mr Heads

US Patent:
2002015, Oct 31, 2002
Filed:
Apr 26, 2001
Appl. No.:
09/844897
Inventors:
Geng Wang - San Jose CA, US
Zhaohui Li - Santa Clara CA, US
Hyung Lee - Cupertino CA, US
International Classification:
G01R033/12
US Classification:
324/210000
Abstract:
A method to test an instability of a magneto-resistive (MR) head. The instability is tested by first writing a signal onto a track. The junctions of the MR head are aligned with various track edges and the head characteristics are then measured. The characteristics may include determining a maximum amplitude covarian and a maximum base line popping noise.
