Abstract

이미 정보가 수록된 2개의 광디스크판중 어느 하나인 제1광디스크판 기록면의 외주면과 내외주면에 접착제를 도포하고, 그 위에 다른 제2디스크판을 압착하여 형성하므로서 주사되는 빛이 기록면에 기록되어 데이터(홈)에 정확히 입사되고 반사되므로 신호특성이 저하되는 것을 방지하는 광디스크 및 그 제조방법에 관한 것이다.Adhesive light is applied to the outer circumferential surface and the inner and outer circumferential surface of the recording surface of the first optical disk plate, which is one of the two optical disk plates, in which information has been already recorded, and the other second disk plate is formed on the recording surface to compress the light to be recorded on the recording surface. The present invention relates to an optical disc and a method of manufacturing the same, which prevent the signal characteristic from deteriorating since it is incident and reflected accurately to a groove.

이미 정보가 수록된 2개의 광디스크판중 어느 하나인 제1광디스크판 기록면의 외주면과 내외주면에 접착제를 도포하고, 그 위에 다른 제2디스크판을 압착하여 형성된 것을 특징으로 하는 광디스크.An optical disc formed by applying an adhesive to an outer circumferential surface and an inner circumferential surface of a recording surface of a first optical disk plate, which is one of two optical disk plates which already contain information, and pressing another second disk plate thereon. 제1항에 있어서, 상기 접착제는 자외선 접착제로서 그 막두께가 약 10∼100㎛인 것을 특징으로 하는 광디스크.The optical disc of claim 1, wherein the adhesive is an ultraviolet adhesive, and has a film thickness of about 10 to 100 μm. 제1항에 있어서, 상기 접착제에 의하여 서로 접착되는 제1,2광디스크판의 기록면에 서로 대향되게 한 것을 특징으로 하는 광디스크.The optical disc of claim 1, wherein the recording surfaces of the first and second optical disc plates adhered to each other by the adhesive are opposed to each other. 제1디스크판의 기록면 내주면과 외주면 소정의 패턴을 갖는 실크스크린을 이용하여 접착제를 도포하는 접착제 도포과정과, 상기 접착제 도포과정에서 접착제가 도포된 제1디스크판 위에 제2디스크판을 접착시키는 디스크 접착제가 도포된 제1디스크판 위에 제2디스크판을 접착시키는 디스크 접착과정과, 상기 디스크 접착과정에서 접착된 제1,제2디스크에 자외선을 주사시켜 접착제를 경화시키는 접착제 경화과정으로 이루어진 것을 특징으로 하는 광디스크 제조방법.An adhesive coating step of applying an adhesive using a silk screen having a predetermined pattern of an inner circumferential surface and an outer circumferential surface of the recording surface of the first disc plate, and a disc for adhering the second disc plate on the first disc plate to which the adhesive is applied during the adhesive application step. A disk bonding process for adhering the second disk plate on the first disk plate to which the adhesive is applied, and an adhesive curing process for curing the adhesive by injecting ultraviolet rays to the first and second disks bonded in the disk bonding process. An optical disc manufacturing method. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
