Title: Ken Fujinaga: Innovator in Disk Device Technology
Introduction
Ken Fujinaga is a notable inventor based in Iwaki, Japan. He has made significant contributions to the field of disk device technology, holding a total of 2 patents. His work focuses on improving the functionality and reliability of disk devices.
Latest Patents
Fujinaga's latest patents include a "Disk device with restricting mechanism for driving unit." This innovative disk device features a driving unit that can move between a withdrawal position and a driving position. The withdrawal position is designed to be separated from the outer peripheral edge of a disk positioned within the housing. The driving position is where the disk is rotationally driven. When the driving unit is at the withdrawal position, the restricting mechanism prevents the driving unit from moving toward the driving position.
Another significant patent is the "Method and device for ejecting disc." This method outlines a process for ejecting a disc that involves conveying the disc back to a disc-holding position on a rotator by conveyor pulleys if an error occurs during the ejecting process. After this, a retry operation of the ejecting process is performed. The disc, once conveyed back to the disc-holding position, is rotated by the rotator before the ejecting process is restarted.
