Latest Patents
Hiruta holds a patent for a "Servo pattern writing method and magnetic disk drive for carrying out the same." This patent describes a method for writing a servo pattern that controls the positioning of a magnetic head on a magnetic disk. The method involves changing the rotating speed of the magnetic disk while the magnetic head is positioned at specific radial locations. The adjustment of the rotating speed is based on the magnitude of synchronous vibrations that occur during the disk's rotation. This technique allows for the writing current to be set according to the changes in the disk's speed, ultimately reducing vibration intensity during the servo pattern writing operation. This innovation enables the servo track writing process to be conducted at a lower cost.
