Abstract
Provided is a manufacturing method of an optical information storage medium irradiated with laser beams to optically record or reproduce information. A method of manufacturing an optical information storage medium according to the present invention includes forming asperity patterns for guiding laser beams on both sides of a second substrate, forming information recording layersandin the asperity patterns, bonding a first substrateto a surface where one information storage layeris formed in the second substratewith an ultraviolet curable resinformed therebetween, and bonding a third substrateto a surface where another information storage layeris formed in the second substratewith an ultraviolet curable resinformed therebetween.
