Latest Patents
One of Richard's latest patents is the "Monolithic CD/DVD Read/Write Head." This invention features a read head optical system capable of reading both CD and DVD disks. The design includes a monolithic molded hollow plastic block that integrates three lenses into its exterior surfaces. A 780 nm laser diode is aligned with the first lens for reading CD disks, while a 655 nm laser is aligned with the second lens for reading DVD disks. Additionally, a detector is aligned with the third molded lens to provide signal, focus, and tracking data. The hollow plastic block is designed to support optical elements that transmit the output of the laser diodes to the disks and the detector.
Another significant patent is the "Single Objective Lens for Use with CD or DVD Optical Disks." This optical disk reader or read/write system utilizes first and second laser diodes operating at different wavelengths. Their output beams are collimated and directed at a single element objective lens, which reflects the beams back through the lens to a photodetector. The lens is designed with a central aperture zone and an outer aperture zone, allowing it to achieve diffraction-limited image quality for both CD and DVD formats.
