Title: Innovations of Kunihiro Hashimoto
Introduction
Kunihiro Hashimoto is a notable inventor based in Iruma, Japan. He has made significant contributions to the field of data recording technologies, holding a total of 4 patents. His work focuses on improving the efficiency and accuracy of data storage and retrieval systems.
Latest Patents
Hashimoto's latest patents include a write-pre-compensation system in a floppy disk drive unit. This system compensates for original write data recorded on recording disc mediums, ensuring that the data can be accurately reproduced using a disc drive apparatus capable of handling varying recording densities. When recording on low-density media, the original write data is corrected by displacing each bit in the direction of the estimated bit shift during reproduction. Conversely, for higher density media, the correction involves displacing each bit in the opposite direction of the estimated bit shift. Another significant patent is the regeneration system for digital magnetic recording information. This apparatus reproduces information recorded on magnetic media by detecting and amplifying the recorded information through a magnetic head device. The amplified signal is processed through a differentiator and a non-ideal integrator, with a compensating device added to handle DC and low-frequency signals.
