Latest Patents

One of Mitamura's latest patents is titled "Phase and period synchronization for a slave disk drive." This invention involves a system where one magnetic disk device acts as a master unit, generating reference signals to synchronize the rotation of other slave units. The method ensures that the conditions of revolution between the master and slave units are compared to maintain synchronism. Index pulses recorded on the magnetic disks serve as reference signals for this synchronization process.

Another significant patent is the "Control method and apparatus for positioning servo system." This invention addresses the challenges of positioning errors in magnetic disc head positioning systems. By utilizing a stepper motor, the system minimizes errors caused by different approach directions and distances to target track positions. The head is temporarily stopped at a position close to the target track, allowing for a more efficient and accurate movement to the desired location.
