first embodiment
[0027]FIG. 1 shows a schematic view showing a construction of an optical disk according to the first embodiment of the present invention. The optical disk includes a substrate 101, a recording film 102 formed on a surface of the substrate 101, an overcoat layer 103 formed on a surface of the recording film 102 and a sheet 105 bonded to the overcoat layer 103 through an adhesive layer 104. The substrate 101 is a substrate (or plate) which is formed by injection molding and has a guide groove wherein wobble information is recorded on its surface where the recording film 102 is formed. The substrate 101 has a thickness of about 1.1 mm. The recording film 102 may be formed by, for example, a spin coat method using an organic dye. The overcoat layer 103 may be formed of a UV curable resin into a thickness of about 4 μm. The sheet 105 may be a polycarbonate sheet (PC sheet) having a thickness of about 80 μm, and it may be bonded to the overcoat layer 103 by the adhesive layer 104 of a UV ...
second embodiment
[0042]FIG. 5 is a schematic view showing a construction of an optical disk of a second embodiment. This disk has two recording films. A second recording film 502 which is located further from a laser light may be formed on a substrate 501 using an organic dye by a spin-coat method. The substrate 501 is produced in the same manner as in the first embodiment. Next, an intermediate layer 503 having a guide groove on its surface is stacked. The guide groove formed in the intermediate layer 503 is used to record information on and reproduce information from a first recording film 504 that is located near to the laser light and it also may be formed using a stamper which is produced with a master. The first recording film 504 whose main component may be a Te oxide film may be formed on a surface of the intermediate layer 503 by a sputtering method. A polycarbonate sheet (PC sheet) 506 having a thickness of about 65 μm is bonded to the surface of the second recording film 504 through a UV ...
