Latest Patents
One of his latest patents is for a dual focus lens with extended depth of focus. This invention involves a magneto-optic or optical disk drive that utilizes a laser source to focus a laser beam onto a recording disk. The lens is designed to focus aberration-free spots on various types of disk media, accommodating different overcoat thicknesses. This innovation allows for continuous focusing of laser light onto the recording media, even when the disk wobbles during rapid spinning. Additionally, it addresses issues related to changes in focal length due to variations in the laser wavelength.
Another significant patent is a method for making an optical or magneto-optic head. This method includes forming a diffractive lens on one side of a glass substrate and creating air bearing surface rails on the opposite side. This approach enables the simultaneous production of multiple heads without the need for bonding lenses onto sliders, thus reducing costs. The invention also includes the deposition of coils on the substrate to generate a magnetic field during write operations.
