Title: Tamotsu Hatakoshi: Innovator in Magnetic Recording Technology
Introduction
Tamotsu Hatakoshi is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of magnetic recording technology. With a total of 2 patents to his name, Hatakoshi's work has advanced the capabilities of magnetic recording mediums.
Latest Patents
Hatakoshi's latest patents focus on the development of a magnetic recording medium. The first patent describes a method where the surface of a non-magnetic base plate is coarsened to achieve the required surface roughness. Ultrasonic vibration is then applied to this surface while it is immersed in a liquid. Following this process, a magnetic recording layer and a protective layer are successively formed on the surface. The frequency of the ultrasonic vibration is ideally maintained between 200 kHz and 1600 kHz. This method allows for the control of surface fractional properties of the magnetic recording medium without affecting the floatation height of a magnetic head during operation.
The second patent outlines a similar method for fabricating a magnetic recording medium. It emphasizes the importance of ultrasonic vibration in achieving the desired surface characteristics. By varying the ultrasonic oscillation output and processing time, the properties of the magnetic recording medium can be finely tuned.
