Title: Taku Iwase: Innovator in Magnetic Recording Technology

Introduction

Taku Iwase is a notable inventor based in Kokubunji, Japan. He has made significant contributions to the field of magnetic recording technology, particularly through his innovative patent.

Latest Patents

Taku Iwase holds a patent for a bit-patterned media magnetic recording disk that features two sizes of dots and an imprint template made with directed self-assembly (DSA) of block copolymers. This advanced technology involves a BPM magnetic recording disk that incorporates both large and small dots of magnetic material arranged in a hexagonal-close-packed (HCP) pattern. In the data regions, the larger dots are strategically placed to avoid adjacency, while in the servo regions, some larger dots are adjacent, forming blocks that enhance the readback signal. The manufacturing process utilizes imprint lithography, and the disks are subsequently exposed to a DC magnetic field to ensure uniform magnetization.
