Abstract

A light wave conductor or fiber optics is withdrawn from the peripheral groove of a rotating storage disc using a deflection pulley or the like rotating in a plane that runs tangential to a circle through the middle of the groove, a pivotal guide lever for the fiber conductor serves as input for speed control of the disc drive. In case of plural withdrawal equipment, the discs are vertically staggered and overlap.
