Title: Shiuh Chao: Innovator in Optical Recording Technologies
Introduction
Shiuh Chao is a notable inventor based in Hawthorne, CA (US), recognized for his contributions to optical recording technologies. He holds a total of 3 patents, showcasing his innovative approach to data storage solutions.
Latest Patents
Chao's latest patents include groundbreaking advancements in optical recording. One of his patents focuses on optical recording using an agglomerating recording medium that changes. This invention involves recording methods, systems, and media that utilize relatively low-power laser means to write digital data bits as reflectance changes for high-density computer storage. The preferred medium comprises a disk support with an anti-reflective surface, on which a non-continuous information layer is laid. This layer is designed to absorb recording radiation from a laser beam, allowing for the writing of bits through agglomeration. The information layer demonstrates surprisingly high sensitivity, suitable for low-power recording, and extended archival stability, without the usual evidence of ablation or pit formation.
Another significant patent by Chao is an optical storage system employing a multi-layer optical medium. This system utilizes a data-modulated writing laser beam and a non-erasing reading laser beam of predetermined wavelength. The improved optical medium consists of multiple layers, with optical characteristics and thicknesses chosen to provide an anti-reflection condition for unrecorded portions and high reflectivity for recorded portions. A preferred optical medium includes a highly reflective aluminum layer, a fluorinated hydrocarbon polymer spacer layer, a nucleation layer, and a gold absorber layer.
