Abstract

Optical recording medium manufacturing includes: providing a first resin on a first recording layer; forming a first intermediate layer by performing first UV irradiation at a first dose to cure the first resin; providing a second recording layer on the first intermediate layer; providing a second resin on the second recording layer; forming a second intermediate layer by performing second UV irradiation at a second dose to cure the second resin; providing a third recording layer on the second intermediate layer; providing a third resin on the third recording layer; and forming a light transmitting layer by performing third UV irradiation at a third dose to cure the third resin. The first and second resins have substantially the same relationships between UV dose received and linear expansion coefficient. The first through third doses are such that UV doses received by the intermediate layers are substantially the same.
