Thermo-Resistive Glide Test Head For Disc Drive Recording Media

View page
US Patent:
62625721, Jul 17, 2001
May 13, 1997
Appl. No.:
Luis Padilla Franco - Gilroy CA
Erich Sawatzky - San Jose CA
Roland Eugene Imboden - Milpitas CA
Seagate Technology LLC - Scotts Valley CA
International Classification:
G01N 2782
G01N 2572
G01B 528
G11B 2736
US Classification:
An improved media defect glide test head assembly which incorporates a wide thermo-resistive (TR) element suitable for detection of thermal asperities on the surfaces of magnetic recording discs. The TR element of the inventive glide test head assembly is very wide when compared to magneto-resistive (MR) elements in normal MR read/write heads. In the currently preferred embodiment, the TR element is envisioned to be as wide as is possible to fabricate on the trailing edge of an air bearing element of the glide test head assembly, to enable detection of thermal asperities across a relatively wide band of disc surface during each disc rotation, thus enabling rapid testing of the media surface. In a second aspect of the invention, the wide TR element is envisioned to be formed of nickel or other material having a large thermal resistance coefficient. In a third aspect of the invention, the wide TR element is envisioned to include intermediary taps which permit more precise mapping of the location of thermal asperities.
