ABSTRACT:
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 interlayer12and a light transmitting layer14provided on the optical recording layer are provided at least one surface of a medium substrate10, for performing recording and reproducing by irradiating a light to the optical recording layers (11, 13) through the light transmitting layer14, 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.
