Latest Patents

One of his latest patents is titled "Method and apparatus for setting magneto resistive head bias current in disk drive for desired head lifetime." This invention focuses on controlling bias supply sources for magneto-resistive transducer (MR) heads. It aims to ensure that the MR heads achieve a predetermined lifetime by determining the dependence of head lifetime on bias supply level and head stripe temperature. The method sets a bias supply level for each head based on this dependence, thereby providing consistent performance.

Another significant patent is the "Method and system for providing electrostatic discharge protection for flex-on suspension, trace-suspension assembly, or cable-on suspension." This invention protects suspension assemblies used with magnetoresistive (MR) heads, which include an MR sensor. The method involves providing leads coupled with the MR sensor and an insulating film that supports these leads. Additionally, a resistor is included to damp transient currents in the MR sensor, enhancing its reliability.
