Latest Patents
Ishii's latest patents include a load/unload mechanism for magnetic disk drives. This invention addresses the formation of wear powder caused by the mutual contact of a lift tab and the ramp during loading and unloading operations. In one embodiment, the spindle motor is activated, and the temperature of the ramp is measured. If the temperature has not reached a preset level of approximately 25°C, a heater is energized to raise the ramp's temperature. Once the desired temperature is achieved, the heating stops, allowing for the execution of loading and unloading operations.
Another notable patent involves a magnetic disk drive operating under low-pressure environments. This invention features an external environment monitoring function that allows data to be stored on available disk media even in unfavorable conditions. When the environment becomes favorable, the data can be moved to a write-restricted area of the media. The magnetic disk drive utilizes temperature and atmospheric pressure sensors to monitor conditions and optimize information storage capacity.
