Title: Hung-Chu Chu: Optical Recording Innovation

Introduction

Hung-Chu Chu is an inventor associated with Taipei, Taiwan, and BenQ Corporation. His patent work addresses optical recording, with a focus on calibrating the defocus used when writing data to optical media.

Latest Patents

Chu is credited with 1 patent: “Optical Recording Apparatus Capable of Optimizing Write Defocus and Method Thereof.” The invention describes an optical pickup that directs light onto an optical medium and detects the reflected signals. A focus motor adjusts the lens position, while a focus controller calibrates write defocus to determine an optimal value for the medium. For a multilayer disc, calibration is performed on the layer targeted for writing. If the optimal value differs from the starting value, the apparatus stores an updated setting.

Career Highlights

Chu’s listed patent reflects work on improving optical recording through medium-specific focus calibration. The disclosed approach is designed to optimize write defocus for the recording layer in use.

Collaborations

Chu’s listed coworkers include Chi-Hung Chen and William Wai Wang. His company affiliation is BenQ Corporation.

Conclusion

Hung-Chu Chu’s patent describes a calibration method for optimizing optical recording focus, highlighting his contribution to recording technology associated with BenQ Corporation.
