Patent

CA 2022005

An optical recording apparatus comprises optical recording mediums each of which comprises a single plate substrate and recording layers which are formed on both sides of the substrate and available for recording and reproduction or for recording, erasing and reproduction with irradiation of laser beams, both surfaces of the recording medium being available for the simultaneous access, and floating type optical thin heads which are provided at every side of the recording mediums and float from the respective surfaces of the recording mediums with maintaining specific distances therefrom for irradiating laser beams onto the recording mediums when the recording mediums are rotated. Combination of these optical recording mediums and optical heads makes it possible to stack plural pairs of them within a thin space, thus improving the on-line capacity of the optical recording apparatus to a great extent.
