Title: Innovations of Kunimasa Kusumoto
Introduction
Kunimasa Kusumoto is a notable inventor based in Saijo, Japan. He has made significant contributions to the field of optical disk technology. With a total of 2 patents, his work focuses on enhancing the stability and performance of optical disk drives.
Latest Patents
Kusumoto's latest patents include an innovative optical disk drive that features gain control to maintain the stability of a servo system. This invention involves performing gain and offset adjustments on a servo error signal during the spin-up of an optical disk. The adjustments help in obtaining a first gain adjustment value and a first offset adjustment value. Based on these values, a CPU calculates a second gain adjustment value and a second offset adjustment value during data writing on the optical disk. These values are stored for later use when transitioning from reading to writing operations.
Another significant patent relates to loop gain adjustment in optical disk apparatuses. This invention ensures that the loop gain adjustment converges normally, even when dealing with mixed prerecorded and recorded areas on an optical disk. The system maintains a stable servo system, even when there are significant variations in gain due to changes in the disk state.
