Title: Makoto Horisaki: Innovator in Magnetic Disk Technology
Introduction
Makoto Horisaki is a prominent inventor based in Odawara, Japan. He has made significant contributions to the field of magnetic disk technology, holding a total of 4 patents. His innovative work has advanced the capabilities of magnetic disk apparatuses, particularly in the areas of servo signal recording and playback.
Latest Patents
Horisaki's latest patents include a magnetic disk apparatus and a servo signal recording method. This invention allows for the generation of a reference clock signal without the need for an external reference. By writing a clock track only once using the head of the magnetic disk apparatus, even with a read/write element separation type head, the system can measure the total number of clock bits in one revolution. The time interval between servo sectors is determined by dividing the total number of clock bits by the number of servo sectors. This method ensures that the servo sectors are recorded at precise intervals using the clock bits produced from the playback of the clock track.
Another notable patent is the magnetic disk apparatus and servo pattern recording method. This invention enables the writing of servo signals with high quality, unaffected by fluctuations in rotation speed during the self-servo write operation. The apparatus comprises a magnetic disk, a head with both write and read elements, and an actuator for positioning the head. The magnetic disk records servo patterns for head positioning, including a pattern sector marker, track ID code, and burst pattern for radial position detection.
