Title: Innovations of Katsuhiko Kaida
Introduction
Katsuhiko Kaida is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of technology, particularly in the area of disk drive systems. With a total of 16 patents to his name, Kaida has demonstrated a strong commitment to innovation and advancement in his field.
Latest Patents
One of Kaida's latest patents is focused on the detection of static and dynamic positions of disk drives. This invention utilizes a 2-axis acceleration sensor that detects both dynamic acceleration, such as shock, and static acceleration, which includes changes in gravity or tilt. The sensor output extraction unit acquires detection signals corresponding to static acceleration for each detection axis by filtering out frequency components associated with dynamic acceleration. A CPU then analyzes these signals to determine if the disk drive is dropping or tilting, allowing for the retraction of the magnetic head to a safe position if necessary.
Another notable patent involves an apparatus and method for head load control in disk drives. In this invention, a head integrated circuit (IC) amplifies the output of a read head that includes magnetoresistive (MR) elements. An analog-to-digital converter (ADC) then converts this amplified output into a digital value. The CPU performs a head load operation to position a composite head onto the data area of a disk medium. It uses the amplified output from the read head to determine whether the head load operation should proceed or be inhibited based on the detection of an external magnetic field applied to the hard disk drive (HDD).
