摘要： A disk-shaped recording medium (2) includes a transparent substrate (5), and an optical recording layer (4) and a magnetic recording layer (3) formed at one side of the transparent substrate (5). An optical head (6) applies light to the optical recording layer (4) from a light source via the transparent substrate, and focuses the light on the optical recording layer and reproduces information from the optical recording layer. A magnetic head (8) records information on the magnetic recording layer (3) or reproduces information from the magnetic recording layer. An optical head moving device (24,23) serves to move the optical head by a movement amount so as to focus the light on an optical track on the optical recording layer which has specified address information. A magnetic head moving device (20,21,22) serves to move the magnetic head to a specified magnetic track on the magnetic recording layer by referring to the movement amount of the optical head.
