Title: Jun Isozaki: Innovator in Magnetic Disk Technology
Introduction
Jun Isozaki is a notable inventor based in Kashiwa, Japan. He has made significant contributions to the field of magnetic disk technology, particularly in the area of servo information recording.
Latest Patents
Isozaki holds a patent for a magnetic disk apparatus, which details a method of forming servo information in a magnetic disk apparatus of a sector servo system. This innovative approach involves recording servo information at the beginning of each sector, which includes a DC erase signal, a track address signal, and a burst signal. The track address signal indicates the specific track on the magnetic disk where the sector is located. It is formed by expressing the track address in Gray code and interleaving a dummy code into the Gray code. The servo information is recorded using either an NRZI system or an RLL coding method. During demodulation, the servo information, which has the dummy code interleaved, is decoded after the dummy code is removed.
