    • An optical disc recording medium includes a disc substrate, at least one recording layer which is disposed on one surface side of the disc substrate, a cover layer which is disposed on a laser incident surface side of the recording layer and which is composed of a light-transmissive resin layer, and a hard coat layer which is disposed for surface protection on a laser incident surface side of the cover layer and which is composed of a light-transmissive resin layer. The cover layer is formed such that its thickness decreases from the central portion to the peripheral portion of the disc, the hard coat layer is formed such that its thickness increases from the central portion to the peripheral portion, and the total thickness of the cover layer and the hard coat layer is substantially uniform from the central portion to the peripheral portion.

    • An optical recording medium wherein characters can be easily recognized on an optical disk irradiated with a light through a light transmitting layer and a method of producing the same are provided. In an optical disk of a type that an optical recording layer is irradiated with a light through a light transmitting protective layer, dealing with a larger capacity, wherein one main surface of a medium substrate 15 is divided to a signal portion SG and a character portion CA, a signal portion uneven shape (15p) is formed on the signal portion SG and a character portion uneven shape (15p) is formed on the character portion CA, and depths of the signal portion uneven shape and the character portion uneven shape are 25 nm or less. Here, it is configured that characters are recorded to be able to be read as normal characters when looking from the medium substrate 15 side (Y-direction) by outlines of a region formed with the character portion uneven shape on the character portion CA.
