Latest Patents
Hata's latest patents include a "Storage control device and rotation speed control method for storage device." This invention provides a storage control device capable of changing the rotation speed of storage devices. A plurality of hard disk drives is mounted in the device mounting unit. The rotation speed control unit detects the mounting location of each hard disk drive and determines the rotation speed in accordance with the location of each hard disk drive. The rotation speeds of adjacent hard disk drives are different from each other. The rotation speed control unit changes the rotation speed of each hard disk drive to the determined rotation speed. Another notable patent is the "Disk device and seek control method." In this invention, when a head passes over a track with a projected item during a seek operation, the CPU delays the seek start time to conduct the seek by changing the period of time from a seek start position to a position of the track with a projected item. This control operation prevents seek errors due to thermal asperity and protects the head from damage.
