Title: Kazuhiko Satake: Innovator in Data Reproducing Technology
Introduction
Kazuhiko Satake is a prominent inventor based in Odawara, Japan. He has made significant contributions to the field of data storage technology, holding 2 patents that enhance data recording efficiency and reduce electromagnetic noise in magnetic disk systems.
Latest Patents
One of Satake's latest patents is a data reproducing apparatus designed to improve data recording efficiency. This invention involves a format control circuit that detects bit synchronization information in a sector to be reproduced on a magnetic disk. When this information is detected, the format control circuit activates a read gate signal to command the reading of the sector. Additionally, when symbol synchronization information is identified, a SYNC detection circuit produces a synchronization information detection signal. The format control circuit then calculates the end position of the sector based on this signal, inactivating the read gate signal. The data correction and decoding circuits reproduce data and error correction codes (ECC) during the active period of the read gate signal, ultimately producing the data and ECC to a data bus.
Another notable patent focuses on adjusting clock frequency in a disk drive and disk system. This innovation aims to reduce electromagnetic noise radiated from a magnetic disk system comprising multiple drives. By setting different operation clock frequencies for each SCSI-ID, the electromagnetic noise from each drive is managed to ensure it does not exceed a certain level, thus maintaining a distinct frequency band for each drive.
