Title: Masayoshi Amasaka: Magnetic Storage and Head-Support Inventions.
Introduction
Masayoshi Amasaka is an inventor associated with Yokohama, Japan. His patent work addresses magnetic storage devices and the support and operation of floating magnetic heads. He is credited with 2 patents.
Latest Patents
Magnetic Storage Device Having a Head Suspension. This invention describes a ramp-loading magnetic storage device designed to keep a magnetic head slider stable as it loads onto or unloads from a storage medium. A loading member connected to the gimbal helps position the slider so its flow-in end remains farther from the medium than its flow-out end, reducing unstable flight.
Air Bearing Head Support. This invention describes a sequence for starting and stopping a magnetic disk drive. At startup, the head contacts the disk before rotation lifts it into a floating position. At shutdown, the head is moved away from the rotating disk before the disk stops. The approach is intended to prevent sticking caused by dew condensation, support a smaller floating space, and enable higher recording density.
