发明名称 OPTICAL RECORDING MEDIUM AND ITS MANUFACTURING METHOD
摘要 An optical recording medium capable of suppressing film thickness irregularity of interlayer between a plurality of optical recording layers and effects of warps of a transfer substrate and arising of dusts and burrs problems, etc. and a method of producing the optical recording medium are provided. An optical recording medium has a structure wherein at least two optical recording layers (11, 13) stacked via an interlayer 12 and a light transmitting layer 14 provided on the optical recording layer are provided at least one surface of a medium substrate 10, for performing recording and reproducing by irradiating a light to the optical recording layers (11, 13) through the light transmitting layer 14, and the interlayer includes at least one layer of ultraviolet curing resin film made to be a film in advance and is a film formed with an uneven shape corresponding to a recording pit or an uneven shape (12p) to be a guide groove on its surface and cured. <IMAGE>
