Method and apparatus of optical information recording medium, and optical information recording medium

A method of manufacturing an optical information recording medium, said manufacturing method comprising:

• bonding a stamper having a principal plane formed with a groove or asperity pits and a first substrate having a first information recording layer with radiation cured resin so as to cause the groove or the asperity pits to face to the first information recording layer, the stamper being transparent, and the groove or the asperity pits having a thin film formed thereon;
• emitting radiation so as to pass at least a part of the radiation through the stamper to cure the radiation cured resin;
• peeling off the stamper to form the groove or the asperity pits on the first information recording layer of the first substrate;
• forming a metal film or a recording film over the groove or the asperity pits on the first substrate to create a second information recording layer on the first substrate;
• and
• forming a light transmission layer over the second information recording layer.

A method of manufacturing an optical information recording medium, said manufacturing method comprising:

• applying first radiation cured resin onto a groove or asperity pits formed on a principal plane of a stamper, the groove or the asperity pits having a thin film formed thereon;
• bonding the stamper and a first substrate having a principal plane on which a first information recording layer is formed with second radiation cured resin such that the first radiation cured resin and the first information recording layer face each other, and curing the second radiation cured resin by emitting radiation so as to pass at least a part of the radiation through the stamper to cure the second radiation cured resin;
• peeling off the stamper to form a groove or asperity pits made of the first radiation cured resin on the first substrate;
• and forming a reflective film or a recording film on the groove or the asperity pits on the first substrate to make a second information recording layer.

A method of manufacturing an optical information recording medium, said manufacturing method comprising:

• applying second radiation cured resin onto a first information recording layer formed on a principal plane of a first substrate, and curing the second radiation cured resin;
• bonding a stamper having a principal plane formed with a groove or asperity pits and the first substrate with first radiation cured resin such that the groove or asperity pits and the second radiation cured resin face each other, the groove or the asperity pits having a thin film formed thereon and curing the first radiation cured resin by emitting radiation so as to pass at least a part of the radiation through the stamper to cure the first radiation cured resin;
• peeling off the stamper to form a groove or asperity pits made of the first radiation cured resin on the first substrate;
• and
• forming a reflective film or a recording film on the groove or the asperity pits on the first substrate to make a second information recording layer.

A method of manufacturing an optical information recording medium, said manufacturing method comprising:

• applying first radiation cured resin onto a groove or asperity pits formed on a principal plane of a stamper, the groove or asperity pits having a thin film formed thereon;
• applying second radiation cured resin onto a first information recording layer formed on a principal plane of a first substrate;
• bonding the stamper and the first substrate such that the first radiation cured resin and the second radiation cured resin face each other, and curing the first and second radiation cured resins by emitting radiation so as to pass at least a part of the radiation through the stamper to cure the first and second radiation cured resins;
• peeling off the stamper to form a groove or asperity pits made of the first radiation cured resin on the first substrate;
• and
• forming a reflective film or a recording film over the groove or the asperity pits on the first substrate to form a second information recording layer.

A method of manufacturing an optical information recording medium, said manufacturing method comprising:

• forming a first thin film comprising at least one layer on a groove or asperity pits formed on a principal plane of a stamper;
• forming a second thin film comprising at least one layer over the first thin film;
• bonding the stamper and a first substrate having a principal plane on which a first information recording layer is formed with radiation cured resin such that the second thin film and the first information recording layer face each other;
• peeling off the stamper and the first substrate at an interface of the first and second thin films to form a groove or asperity pits made of the second thin film on the first substrate;
• and
• forming a reflective film or recording film on the groove or the asperity pits on the first substrate to form a second information recording layer.
