Title: Innovations of Toru Kuroe in Magnetic Disc Technology

Introduction

Toru Kuroe is a notable inventor based in Machida, Japan. He has made significant contributions to the field of magnetic disc technology, holding a total of 2 patents. His work focuses on improving the performance and efficiency of magnetic discs through innovative substrate designs.

Latest Patents

Kuroe's latest patents include a substrate for a magnetic disc that features a glass substrate with fine protrusions on its surface. These protrusions have a height ranging from 50 to 1000 angstroms, a width of 0.01 to 1 micrometer, and a density of 10 to 1000 per 100 square micrometers. The area ratio of these protrusions is between 0.1 to 50%. The design also specifies a ratio of peak height on a mean line (R_p) to maximum height (R_max) with respect to surface roughness of at least 60%. This innovative substrate reduces friction and adsorbing forces between the head and the magnetic disc, enhancing the CSS and anti-head stick properties. Additionally, the signal-to-noise (S/N) ratio remains unaffected due to the shallow fine concave portions on the substrate's surface.
