Title: The Innovations of Takashi Ichikawa
Introduction
Takashi Ichikawa is a notable inventor based in Suwa, Japan. He has made significant contributions to the field of disk drive technology, holding 2 patents that enhance the functionality and efficiency of spindle motors in disk drives.
Latest Patents
Ichikawa's latest patents focus on head positioning control for spindle motor disk drives. The first patent describes a disk drive that includes a data recording disk and a disk head for recording and reproducing data. The system features arms that support the disk head, with an actuator that drives the arm to move the disk head to a predetermined data recording track. The spindle motor rotates the disk, and the actuator unit selects the track on the disk. The control system is designed to manage the positioning of the disk head based on first and second positioning data, which may be located on tracks not used for data. This innovative approach allows for improved accuracy in head positioning.
The second patent also addresses head positioning control in spindle motor disk drives. It outlines a similar structure, where the disk heads are supported on arms and driven by a head actuator. The spindle motor's rotor magnet is positioned within a stator coil, and the system compensates for head positioning using stored second positioning information superimposed on the first positioning data. This dual data approach enhances the reliability and precision of data retrieval.
