Abstract:
An optical pick-up apparatus which optically performs at least one of selective recording of information onto a plurality of recording layers of an optical recording medium, and selective reproduction of information from the plurality of recording layers, comprising:optical circuits which are each adapted to guide a light beam to a desired recording layer using a movable mirror, to thereby perform selective recording of information onto the plurality of recording layers of the optical recording medium or selective reproduction of information from the plurality of recording layers, wherein a plurality of optical recording mediums are arranged in layers, and the movable mirror selectively guides a light beam between each pair of adjacent ones of the optical recording mediums arranged in layers, and another movable mirror which is provided between said each pair of the adjacent optical recording mediums and selectively guides the light beam selectively guided by the first-mentioned movable mirror, to one of two recording layers opposed to each other and provided on said each pair of the adjacent optical recording mediums.
