INTEGRATED FIELD GENERATOR FOR ACTUATING MAGNETIC HEADS

摘要

A structure is integrated into the design and manufacture of a magnetic head that allows self-generation of magnetic fields. The structure includes a conductor or conductors placed in close proximity to the read portion of a magnetic head and connected to an externally accessible connection. A high frequency signal is passed through the conductor to generate a magnetic field through the read device and simulate, for example, the head crossing magnetic domains on a magnetic memory disk.
