Abstract:
1. A manufacturing method for an optical data recording medium, said method comprising: preparing a first substrate; applying a first radiation curable resin to a side of the first substrate; curing a first part of the first radiation curable resin such that a second part of the first radiation curable resin is uncured; preparing a second substrate having a groove or lands and pits on one side; applying a second radiation curable resin to the side of the second substrate having the groove or the lands and pits; curing a first part of the second radiation curable resin such that a second part of the second radiation curable resin is uncured; laminating the first radiation curable resin of the first substrate and the second radiation curable resin of the second substrate together after both of the first and second radiation curable resins are partially cured in said curing of the first part of the first radiation curable resin and said curing of the first part of the second radiation curable resin; curing the uncured second part of the first radiation curable resin and the uncured second part of the second radiation curable resin after the first radiation curable resin of the first substrate and the second radiation curable resin of the second substrate are laminated together in said laminating of the first radiation curable resin of the first substrate and the second radiation curable resin second substrate together; and removing the first substrate after the uncured second part of the first radiation curable resin and the uncured second part of the second radiation curable resin are cured in said curing of the uncured second part of the first radiation curable resin and the uncured second part of the second radiation curable resin.
