Latest Patents

Kawaguchi holds a patent for a "Servo pattern writing method and apparatus thereof." This invention ensures that the center of rotation of a disk medium coincides as accurately as possible with its center of rotation in the drive into which the disk medium is assembled. The magnetic disk medium is fixed to a spindle hub, and a centering pin of a push-aside mechanism pushes aside the magnetic disk medium with respect to the center of the spindle hub until the disk-to-hub gap is moved to one side. Subsequently, a centering pin of a come-back mechanism is placed in the same line intersecting with the center of the spindle, allowing the magnetic disk medium to be pushed back to the opposite side.
