Introduction

Toshio Kazama is an inventor associated with Niigata, Japan, whose work includes innovations in magnetic recording head design. His listed portfolio includes 13 patents, and his career is associated with Alps Electric Co., Ltd.

Latest Patents

Kazama’s listed patents include “Magnetic Head Device Supported by a Bent Load Beam.” The invention describes a magnetic head designed to reduce sideways movement of the head body while allowing a pressing force to keep it in contact with a recording medium. Its structure includes a carriage, an elastically deformable support member, and a head body. The support member connects to a bent portion of the carriage, with the bend helping provide a stable support point.

Another listed patent is “Thin Magnetic Head Having a Cover Provided on a Planar Coil.” It describes a magnetic head with a pole core and a thin-film planar coil wound around it, along with a cover made from ceramic or a similar material. The planar coil enables a thinner head and can be positioned close to the pole core’s end, supporting more efficient magnetic-field generation and improved recording performance.
