  • Publication number: 20050018548
    Abstract: A recording/reproducing device using a magneto-optical disc as a recording medium having a holder for holding a magneto-optical disc and moving the magneto-optical disc between a disc unloading position and a disc loading position, a turntable for rotating the magneto-optical disc, an optical pickup for casting a light beam onto a signal recording surface of the magneto-optical disc, a magnetic head arranged to face the optical pickup on the opposite sides side of the magneto-optical disc and moving toward and away from the magneto-optical disc, and a rotating ejection lever positioned on a base for ejecting the magneto-optical disc held by the holder. Since the ejection lever is arranged on the side of the base where the optical pickup is arranged, the space within the device body is effectively used, thus realizing miniaturization.
