Title: Kazuo Chokki: Innovator in Magnetic Disk Technology
Introduction
Kazuo Chokki is a notable inventor based in Fujisawa, Kanagawa, Japan. He has made significant contributions to the field of magnetic disk technology, holding a total of 5 patents. His work has been instrumental in advancing data storage solutions.
Latest Patents
Chokki's latest patents include innovative designs for magnetic disk devices and control methods. One of his patents describes a magnetic disk device that incorporates a memory and a controller. This device features a counter, a counter threshold, and weights that are set for divided areas of a predetermined track. The weights are inversely proportional to the guaranteed number of times data can be read out. The controller manages writing to adjacent tracks by multiplying the number of writes by the corresponding weight and updating the counter accordingly. When the counter reaches the threshold, the controller either refreshes the data or determines if a refresh is necessary.
Another patent focuses on a data protection method for magnetic disk devices. This invention includes a monitoring unit that oversees the supply voltage to actuators. It uses two threshold values to manage the power supply effectively. If the supply voltage falls within a specific range, the controller interrupts data reading or writing processes based on predetermined conditions.
