Title: Kazuhiro Momata: Innovator in Magnetic Recording Technology

Introduction

Kazuhiro Momata is a prominent inventor based in Chigasaki, Japan. He has made significant contributions to the field of magnetic recording technology, holding a total of 12 patents. His work has been instrumental in advancing the capabilities of magnetic recording and reproducing systems.

Latest Patents

Among his latest innovations is a magnetic recording/reproducing head assembly. This assembly comprises a first magnetic path forming member on which a coil is mounted, and a second magnetic path forming member that cooperates with the first to form a magnetic path. Additionally, it features a film laminate formed at a front gap portion between the two magnetic path forming members. This film laminate includes a magnetic detecting element for detecting changes in a magnetic field, along with a soft magnetic film or films. The assembly is prepared 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 of the head. The gap length and/or magnetostriction constant is determined to ensure that the saturation operation current, which maximizes the reproduction output, is higher than the operation current required for the head to function.
