Title: Innovations of Kenneth E Johnson
Introduction
Kenneth E Johnson is a notable inventor based in Morgan Hill, California. He holds a total of seven patents, showcasing his contributions to the field of technology and engineering. His work primarily focuses on advancements in magnetic disk drive technology.
Latest Patents
One of his latest patents is a high sensitivity glide sensor using frictional heating. This innovative tool is designed for testing magnetic disks used in magnetic disk drives. It detects surface defects or asperities by measuring changes in electrical resistance that correspond to temperature changes in a thermally sensitive layer. The apparatus features a slider body with a thermally insulating layer on its air bearing surface, which prevents thermal heat spikes from dissipating quickly. The thermal sensor layer is made from a material that exhibits a significant change in electrical resistance in response to temperature changes, preferably a PTC thermistor material.
Another significant patent is for one-sided magnetic media for low-cost and low-capacity applications. This invention involves creating magnetic media for hard disk drives that only utilizes one surface for data recording. The second surface is designed as a non-data recording side, ensuring it does not interfere with the recording properties of the primary side. Additionally, this second surface can be a lower quality surface capable of limited magnetic recording.
