Latest Patents

Kouhara's latest patents include a magnetic disk device and a manufacturing method thereof. This invention involves a controller for a magnetic disk device that acquires a reproduction signal of servo burst data while moving a magnetic head along data tracks that intersect servo tracks at multiple points. The controller acquires correction values for correcting repeatable runout on a per servo sector basis based on the reproduction signal. These correction values consist of a first correction value for a servo sector where the data track and the servo track are substantially parallel, and a second correction value for a servo sector where they are not. The controller adjusts the first correction value based on the second and writes these values onto a magnetic disk.

Another significant patent is a magnetic disk device and write method. In this embodiment, the device includes a disk and a controller that calculates a first corrected value based on the disk's first eccentricity. The controller writes a first track based on this corrected value. If the writing process for a second track overlaps the first track at a specific position, the controller measures the second eccentricity of the disk and compares it with the first. If there is a difference, the controller restarts the writing process from a new position in a radial direction.
