- a circular recess 3 for coupling with an optical recording medium rotating device is formed substantially near the center.
- This circular recess 3 is formed in a cylindrical shape c Further, a magnetic body 4 is provided in the substrate around the circular concave portion, and fits with the convex portion of the chuck portion 9 of the rotating device so as to be coupled and fixed by magnetic force. On the other surface 5, a recording area 8 for recording optical information is formed. Further, a resin 7 is coated on the upper layer of the recording area for protection of recorded information, and design printing is performed on the surface. The entire surface on which the design printing is applied is flat, and the entire surface is designed as shown in FIG.
- the description is of a type in which a magnetic material is built in the substrate, but a metal piece may be built in the substrate and the magnetic material may be arranged on the chuck 9.
- the optical information recorded in the recording area 8 is read by irradiating a laser beam from the direction of the surface 6.
- FIG. 4 shows a second embodiment according to the present invention.
- the second embodiment differs from the first embodiment in that a circular shallow recess is formed instead of a cylindrical recess, and a circular recess 10 is formed. It is built into the unit.
- a magnetic material or a metal piece may be disposed on the substrate, and a configuration that is paired with the chuck portion 9 is desirable.
- the chuck 9 has an annular protrusion which is inset with the annular recess 10. The center of rotation is determined by matching the protrusion with the annular concave portion 10.
