Latest Patents
One of his latest patents is a method for fabricating a lens/mirror tower. This invention involves a lens/mirror tower (LMT) of a multiple-disk array, which includes a plurality of lens and mirror elements integrally formed on a monolithic, optically-clear substrate. Each recording disk surface of the optical storage device has a specific lens/mirror set, with the mirror elements configured as one reflective surface of the substrate. The lenses are molded onto the opposite surface in a single operation that fixes their relative positions. The LMT is generally fabricated using a lens replication process, starting with a glass substrate formed in a trapezoidal configuration. A lens array mold is created with overlapping cavities filled with optical-quality resin, which, once cured, serves as an array of lenses aligned with the optical paths to the objective lenses of the disk array.
Another significant patent is the remote fine positioning mechanism of an optical storage device. This mechanism includes a stationary galvanometer-controlled mirror (galvo mirror) and an imaging lens. The imaging lens is positioned to provide an image of the galvo mirror at the front focal point of an objective lens mounted to an optical head assembly. The galvo mirror acts as a beam steering element, changing the angle of incidence of a collimated laser beam during track selection operations. This innovative design allows for precise control of the laser beam direction, enhancing the functionality of optical storage devices.
