Title: The Innovations of Richard H Ahlert: A Pioneer in Magnetic Disk Technology

Introduction

Richard H Ahlert, based in San Jose, California, is an accomplished inventor with an impressive portfolio of 12 patents. His innovative contributions primarily focus on magnetic disk technology, particularly the development of boron carbide overcoat layers that enhance the durability of magnetic disks.

Latest Patents

Ahlert's latest patents include a method of making a magnetic disk with a boron carbide overcoat layer. This invention presents a significantly thinner boron carbide overcoat layer that offers the same durability as thicker alternatives found in prior art. By utilizing adhesion layers composed of materials such as Ge, Ru, WTiSi, WTi, Si, and Y between the magnetic layer and the overcoat layer, Ahlert has effectively increased the durability of the overcoat layer compared to a single overcoat layer of boron carbide (B4C). Furthermore, specific process steps in manufacturing the B4C overcoat layer provide enhancements in durability, maintaining the disk at a floating potential in a plasma chamber while using low levels of argon pressure and sputtering wattage.
