RECORDING AND REPRODUCING APPARATUS

摘要

A disk-shaped recording medium includes a transparent substrate, and an optical recording layer and a magnetic recording layer formed at one side of the transparent substrate. An optical head applies light to the optical recording layer 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, located at a side of the recording medium opposite the side thereof where the optical head is located, records information on the magnetic recording layer or reproduces information from the magnetic recording layer. An optical head moving device 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 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.
