Abstract

Abstract There is provided a method of curing an optical disc capable of effectively curing the optical disc without generating a warp phenomenon when optical disc is cured while ultraviolet curing resin material is irradiated with ultraviolet. The method of curing an optical disc comprises overlaying first and second resin substrates onto each other by way of an adhesive made of ultraviolet curing resin material, the method further comprising clamping the optical disc by ultraviolet transmittance plates at both sides thereof, and curing the adhesive while being irradiated with ultraviolet from outside of the ultraviolet transmittance plates.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 63 words
A method of bonding optical disc substrates to create an optical disc including first and second overlaid substrates having an adhesive made of ultraviolet curing resin material interposed therebetween, said method comprising: clamping said overlaid optical disc substrates between ultraviolet transmittance plates provided at both sides thereof, and curing said adhesive by irradiating same with ultraviolet from outside of said ultraviolet transmittance plates.
Claim 2
Independent Claim 63 words
A method of bonding optical disc substrates to create an optical disc including first and second overlaid substrates having an adhesive made of ultraviolet curing resin material interposed therebetween, said method comprising: clamping said overlaid optical disc substrates between ultraviolet transmittance plates provided at both sides thereof, and curing said adhesive by irradiating same with ultraviolet from outside of said ultraviolet transmittance plates.
Claim 3
Dependent Claim 34 words
The method of bonding substrates according to claim 1, wherein the step of curing includes reflecting irradiation toward the periphery of the optical disc substrates so as to cure the periphery of the adhesive.
Claim 4
Dependent Claim 34 words
The method of bonding substrates according to claim 1, wherein the step of curing includes the step of moving said optical disc substrates past irradiators so as to expose said adhesive to the irradiation.
Claim 5
Dependent Claim 39 words
The method of bonding substrates according to claim 3, wherein the step of moving includes simultaneously rotating said optical disc substrates as the substrates are moved past the irradiators so as to uniformly expose the adhesive to the irradiation.
Claim 6
Dependent Claim 68 words
The method of bonding substrates according to claim 1, wherein the step of curing includes supporting the overlaid substrates on adjacent first and second belts, and moving said belts at one of a same velocity so as to nonrotatably move the overlaid substrates past irradiators for curing the adhesive and differing velocities so as to simultaneously rotate and move the overlaid substrates past irradiators for curing the adhesive.
Claim 7
Dependent Claim 25 words
The method of bonding according to claim 1, wherein the step of curing includes transmitting at least some of the ultraviolet through the transmittance plates.
Claim 8
Independent Claim 83 words
A method of bonding optical disc substrates to create an optical disc including first and second overlaid substrates having an adhesive made of ultraviolet curing resin material interposed therebetween, said method comprising: clamping said overlaid optical disc substrates between ultraviolet transmittance plates provided at both sides thereof; moving said optical disc substrates between ultraviolet irradiators while said optical disc substrates are clamped between said ultraviolet transmittance plates; and curing said adhesive by irradiating same with ultraviolet from outside of said ultraviolet transmittance plates.
Claim 9
Independent Claim 83 words
A method of bonding optical disc substrates to create an optical disc including first and second overlaid substrates having an adhesive made of ultraviolet curing resin material interposed therebetween, said method comprising: clamping said overlaid optical disc substrates between ultraviolet transmittance plates provided at both sides thereof; moving said optical disc substrates between ultraviolet irradiators while said optical disc substrates are clamped between said ultraviolet transmittance plates; and curing said adhesive by irradiating same with ultraviolet from outside of said ultraviolet transmittance plates.
