Title: Kyoko Miyabe: Optical Recording and Reproduction Inventions.

Introduction

Kyoko Miyabe is an inventor associated with Kawasaki, Japan, and Fujitsu Corporation. Her patent work includes optical information recording and reproduction technology. The available information credits her with 11 patents.

Latest Patents

Miyabe’s listed latest patent concerns an optical information recording/reproducing apparatus. The apparatus records information on, or reproduces information from, an optical recording medium by analyzing light reflected from it.

The design uses multiple light-splitting stages to divide the reflected beam into several beams, which are received by an array of photodetectors. Different detectors support focal-error detection, tracking-error detection, and the detection of magneto-optic information recorded on the medium. This arrangement brings several optical sensing functions together in one apparatus.

Career Highlights

Miyabe’s patent portfolio reflects work on optical systems that combine light processing and signal detection. Her listed invention addresses the coordinated detection needed to read and record information on optical media.

Collaborations

The provided information identifies Koichi Tezuka and Tohru Fujimaki as Miyabe’s coworkers. It does not specify their roles in the listed patent.

Conclusion

Kyoko Miyabe’s documented patent work focuses on optical recording and reproduction, particularly an apparatus that splits reflected light to support multiple detection functions.
