Latest Patents

Katsumata's latest patents include a magnetic recording/reproducing head assembly. This assembly comprises a first magnetic path forming member with a mounted coil, a second magnetic path forming member that cooperates with the first, and a film laminate positioned at the front gap between the two members. The film laminate features a magnetic detecting element for sensing changes in a magnetic field, along with one or more soft magnetic films. The assembly is constructed by forming the film laminate on a head base, bonding a core member to the head base, and mounting a coil on the core member.

Another notable patent is for a magnetoresistive head that includes a magnetoresistive element. This head is designed with a specifically determined gap length and/or a magnetostriction constant, which defines the reproduction output versus operation current characteristic curve. The design ensures that the saturation operation current, which maximizes the reproduction output, is higher than the operational current required for the head to function effectively.
