US Patent:

6472866, Oct 29, 2002
Filed:

Feb 9, 2001
Appl. No.:

09/780315
Inventors:

Mohammad S. Aslami - Loveland CO
Assignee:

Seagate Technologies LLC - Scotts Valley CA
International Classification:

G01R 3312
US Classification:

324210, 324537
Abstract:

A system for testing the read/write head elements of a head stack assembly (âHSAâ). A completed HSA is placed in the test apparatus. Test probes are aligned and placed in electrical contact with the electrical leads coming from each head element, between the head elements and the preamplifier. The HSA is then placed in a changing magnetic field. A low frequency magnetic field can be applied to test the head elements. The changing magnetic field induces electrical signals within the head elements. By analyzing these electrical signals, the condition and characteristics of the each head element can be determined.

Seagate Technology LLC - Scotts Valley CA
International Classification:

G01L 2500
US Classification:

702115
Abstract:

A system for testing inductive write head elements of a head stack assembly (âHSAâ). A completed HSA is placed in a test apparatus. Test probes are aligned and placed in electrical contact with the head elements, preferably at a location between the head and the preamplifier. The HSA is then placed in a changing magnetic field. A low frequency magnetic field may be applied to test the head elements. The changing magnetic field induces electrical signals within the head elements. By analyzing these electrical signals, the condition and characteristics of the each head element can be determined.
