PURPOSE:To prevent flaking of a reflecting layer and to simplify the manufacturing process, by providing the reflecting layer on an information recording surface except for the circumference of a recording medium and sticking a label on the entire surface. CONSTITUTION:Ring-shaped masks 6 and 7 are located on an inner circumference 4 and an outer circumference 5 which are nonrecording part on a transparent base 1 and a reflecting layer 8 is formed by vapor deposition or sputtering of aluminum. An adhesives 10 is coated on the entire surface and a label (protector) 12 provided with a display part 13 is stuck. Since the bonding strength of the base and the label is considerably high, the flaking of the reflecting layer 8 can be prevented. Since the protective layer 12 cannot necessarily be provided additionally, the manufacturing stage can be simplified. |
