Abstract

PURPOSE:To mitigate a stress generated upon absorbing moisture, permit the restriction of generation of a crack in a radiation curing resin layer and improve the reliability of the base of a disc, by interposing a stress mitigating layer between a primer layer and the radiation curing resin layer. CONSTITUTION:A stress mitigating layer, whose water absorption expansion coefficient shows an intermediate value between those of a primer layer and a radiation curing resin layer, is interposed as a method wherein the pattern of a disc is not broken upon mold releasing from a stamper and cracks are not generated in the radiation curing resin layer, while the stress mitigating layer is formed by incorporating a primer into the radiation curing resin. The primer, having a small water absorption expansion coefficient, is selected to coat a primer layer 2 on the base 1, thereafter, the stress mitigating layer 4, having the water absorption expansion coefficient smaller than that of the primer layer 2, is formed. The radiation curing resin layer 3, provided with a proper hardness, is coated on the stress mitigating layer 4 and the pattern is formed by the stamper, whereby the base of a disc, excellent in a bonding property between the base 1 and prevented from the generation of cracks due to water absorption, may be manufactured.
