Abstract
High-density optical data storage comprising multi-layer optical disc and multi-wavelength reading/recording head, wherein the reading/recording head utilizes a single-mode optic fiber connecting the head with remote short-wavelength laser and acousto-optical (AO) cells that allow precisely positioning the focused light spot on the track and filtering the specific wavelength from multi-wavelength light emitted by the laser built in the head.
