Document Type and Number:
Japanese Patent JP4338688
Kind Code:
B2
Abstract:
An optical disc manufacturing method suppresses thickness variation in intermediate layers disposed between any two substrates luminated together to achieve an intermediate layer of uniform thickness.
In a first step a radiation curable resin (214) is coated on a first substrate (211).
In a second step the radiation curable resin (214) is cured in a part of the surface of the first substrate (211).
In a third step a resin material (204) is coated on a second substrate (201) having a groove or lands and pits (203).
In a forth step the radiation curable resin (214) of the first substrate (211) is laminated on the resin material (204) of the second substrate (201).
