Title: Takumi Sasaki: Innovator in Magnetic Thin Film Technology

Introduction

Takumi Sasaki is a prominent inventor based in Yokohama, Japan. He is known for his significant contributions to the field of magnetic thin film technology, particularly in the development of advanced recording and reproducing systems for electronic still cameras.

Latest Patents

Sasaki holds a patent for "Multi-track magnetic thin film heads." This innovative technology is designed for recording and reproducing analog signals in electronic still cameras. The heads are constructed on a single non-magnetic substrate, which enhances performance and reduces interference. Each lower magnetic core is separately formed on the substrate to minimize cross talk from adjacent tracks. Additionally, the design features a larger distance between the back head gap parts of adjacent heads compared to the front head gap parts, which decreases coil resistance. The materials used include a ceramic substrate with MnO and NiO, an amorphous magnetic core material containing Co, Nb, and Zr, and Cr or Zr as the magnetic gap material.
