본 발명은 홀로그래픽 롬(holographic ROM)에 관한 것으로, 특히 효율적인 DVD 호환 홀로그래픽 롬용 디스크 제조방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to holographic ROM, and more particularly to a method for manufacturing a disc for DVD compatible holographic ROM.

일반적으로 DVD 호환 홀로그래픽 롬 디스크의 제조 공정에서는 코니컬 미러(conical mirror)를 이용한 홀로그램 데이터 복제가 완료된 후에 디스크 내부의 기록물질인 포토 폴리머(photo-polymer)에 잔류하는 모노머(monomer)를 제거하기 위해서 자외선(Ultra Violet: UV)을 조사하여 모노머를 제거하는 자외선 컬링(curing) 공정이 별도로 수행되고, 이후 반사층(reflective layer)을 포함하는 상부 서브스레이트층(substrate layer)를 기록 완료된 디스크에 본드(bond)를 이용하여 접착시켜 도 1에서 보여지는 바와 같이 하부 서브스트레이트층 (106, 110), 포토폴리머층(108), 본딩층(bonding layer)(104), 반사층(reflective layer)(102)을 포함하는 상부 서브스트레이트층(substrate layer)(100) 구조의 DVD 호환 홀로그래픽 롬 디스크를 제조하였다. In general, a DVD-compatible holographic ROM disc manufacturing process removes monomers remaining in the photo-polymer recording material inside the disc after holographic data copying is completed using a conical mirror. In order to remove the monomers by irradiating ultraviolet (Ultra Violet), a UV curling process is separately performed, and then an upper substrate layer including a reflective layer is bonded to the recorded disk. bond to bond the lower substrate layers 106 and 110, the photopolymer layer 108, the bonding layer 104 and the reflective layer 102 as shown in FIG. A DVD compatible holographic ROM disc having an upper substrate layer 100 structure was prepared.

상기에서 홀로그래픽 디스크에 홀로그램을 기록하여 디스크를 복제한 후, 잔류 모노머를 자외선을 조사하여 제거하는 이유는 잔류 모노머가 남아 있는 경우 이 잔류 모노머가 데이터 재생 시 입사되는 기준광에 반응하여 노이즈 격자(noise grating)를 생성시키기 때문이다.The reason for replicating the disk by recording a hologram on the holographic disk and removing the residual monomer by irradiating with ultraviolet rays is that when the residual monomer remains, the residual monomer reacts to a reference light incident upon data reproduction to generate a noise grating. grating).

도 2는 종래 DVD 호환 홀로그래픽 롬 디스크의 데이터 제조 공정을 도시한 것이다.2 illustrates a data manufacturing process of a conventional DVD compatible holographic ROM disc.

즉, 종래에는 상기 도 2의 (a)에서 보여지는 바와 같이 코니컬 미러(conical mirror)(200)를 이용하여 홀로그램 데이터의 복제를 수행하며, 홀로그램 데이터 복제가 완료된 디스크 내부의 기록물질인 포토폴리머(108)에 잔류하는 모노머(monomer)를 제거하기 위해 도 2의 (b)에서와 같이 자외선(202)을 조사하여 모노머를 제거하는 좌외선 컬링 공정을 별도로 수행한 후, 도 2의 (c)에서와 같이 반사층(102)을 포함하는 상부 서브스트레이트층(100)를 기록 완료된 디스크에 본딩층(104)을 이용하여 접착하는 디스크 본딩 공정을 포함하는 3단계 공정으로 홀로그램 데이터 제조가 수행되어 왔다.That is, in the related art, hologram data is replicated using a conical mirror 200 as shown in FIG. 2A, and a photopolymer which is a recording material inside a disk on which hologram data replication is completed. In order to remove the monomer (108) remaining in the (108), as shown in (b) of FIG. As described above, hologram data manufacturing has been performed in a three-step process including a disk bonding process of bonding the upper substrate layer 100 including the reflective layer 102 to the recorded disk using the bonding layer 104.

그러나 위와 같이 종래 3단계 공정을 거쳐 DVD 호환 홀로그래픽 롬 디스크를 제조하는 방법에서는 홀로그래픽 데이터의 복제를 완료한 후에 반사층이 포함된 상부 서브스트레이트층을 본딩 하여야 하는 추가의 공정이 필요하게 되어 제조 공정수가 늘어나며, 디스크 제조 경비 또한 증가되는 문제점이 있었다.However, in the method of manufacturing a DVD-compatible holographic ROM disc through the conventional three-step process as described above, an additional process of bonding the upper substrate layer including the reflective layer after bonding the holographic data is completed is required. Increasing the number, there was a problem that also increases the disk manufacturing costs.

따라서, 본 발명의 목적은 효율적인 DVD 호환 홀로그래픽 롬용 디스크의 제조방법을 제공함에 있다.Accordingly, it is an object of the present invention to provide an efficient DVD compatible holographic ROM disc manufacturing method.

상술한 목적을 달성하기 위한 본 발명은 DVD 호환 홀로그래픽 롬 디스크를 효율적으로 제조하는 방법으로서, (a)코니컬 미러를 이용하여 홀로그래픽 디스크 상에 홀로그램 데이터를 기록시키는 단계와, (b)상기 홀로그램 데이터가 기록된 홀로그래픽 디스크 상부에 UV 경화용 본드를 이용하여 반사층이 포함된 상부 서브스트레이트층을 접합시키는 단계와, (c)상기 홀로그래픽 디스크와 UV 경화용 본드층으로 자외선을 조사하여 홀로그래픽 디스크내 모노머를 제거시키고, 본드를 경화시켜 DVD 호환 홀로그래픽 롬 디스크를 완성시키는 단계를 포함하는 것을 특징으로 한다.The present invention for achieving the above object is a method for efficiently producing a DVD-compatible holographic ROM disk, (a) recording the holographic data on the holographic disk using a conical mirror, and (b) Bonding the upper substrate layer including the reflective layer to the holographic disk on which the hologram data is recorded using a UV curing bond; and (c) irradiating UV light to the holographic disk and the UV curing bond layer to Removing monomers in the graphics disc and curing the bond to complete the DVD compatible holographic ROM disc.

이하, 첨부된 도면을 참조하여 본 발명에 따른 바람직한 실시 예의 동작을 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail the operation of the preferred embodiment according to the present invention.

도 3은 본 발명의 실시 예가 적용되는 홀로그래픽 롬 시스템을 간략하게 도시한 블록 구성도이다. 상기 도 3을 참조하면, 본 발명이 적용되는 홀로그래픽 롬 시스템은 광원(10), HWP(Half Wave Plate)(12, 22)과, 광 확장기(beam expander)(14), 그리고 편광 분리기(polarizer beam splitter)(16), 편광기(18, 24), 반사 미러(20, 26, 28), 코니컬 미러(conical mirror)(30), 광 기록매체(32), 마스크(34) 등으로 구성된다. 3 is a block diagram schematically illustrating a holographic ROM system to which an embodiment of the present invention is applied. Referring to FIG. 3, the holographic ROM system to which the present invention is applied includes a light source 10, a half wave plate (HWP) 12 and 22, a beam expander 14, and a polarizer. beam splitter 16, polarizers 18, 24, reflective mirrors 20, 26, 28, conical mirror 30, optical record carrier 32, mask 34, and the like. .

이하 위 도 3을 참조하여 홀로그래픽 롬 시스템의 동작을 살펴보면, 먼저 홀로그래픽 롬 시스템은 기록을 위한 두 개의 광 경로를 통해 신호광(signal beam)과 기준광(reference beam)을 광 기록매체(optical media)(32)인 광 디스크에 조사하여 이들 광 사이의 간섭으로 인해 생성되는 간섭 무늬 패턴으로 3차원 홀로그래픽 데이터를 기록한다.Hereinafter, referring to FIG. 3, an operation of the holographic ROM system is performed. First, the holographic ROM system transmits a signal beam and a reference beam through optical paths through two optical paths for recording. The optical disk (32) is irradiated to record three-dimensional holographic data in an interference fringe pattern generated by the interference between these lights.

광원(light source)(10)으로부터 입사되는 광은 예들 들어 532nm 파장의 레이저광이 될 수 있으며, 위 광원(10)으로부터의 입사광은 HWP(12)와, 광 확장기(14) 등을 거쳐 편광 분리기(16)로 제공된다. The light incident from the light source 10 may be, for example, a laser light having a wavelength of 532 nm, and the incident light from the light source 10 passes through the HWP 12, the optical expander 14, and the like, to form a polarization splitter. Provided at 16.

그러면 편광 분리기(16)는 레이저광(laser beam)을 신호광(signal beam)과 기준광(reference beam)으로 분리하는 역할을 하는데, 신호광은 그대로 투과시키고 기준광은 반사시켜 두 개의 광 경로로 나눈다. 편광 분리기(16)에서 분리된 신호광 은 편광기(18)를 거쳐 반사 미러(20)에 의해 반사되고 반사된 신호광은 마스터링 프로세스(mastering process)용 마스크(34)를 투과하여 소정 패턴으로 변조되어 광 기록매체(32)인 광 디스크에 조사된다.Then, the polarization separator 16 separates a laser beam into a signal beam and a reference beam, and transmits the signal beam as it is and reflects the reference beam into two optical paths. The signal light separated by the polarization separator 16 is reflected by the reflection mirror 20 through the polarizer 18 and the reflected signal light is modulated into a predetermined pattern by passing through the mask 34 for the mastering process. The optical disk serving as the recording medium 32 is irradiated.

그리고 편광 분리기(16)에서 분리된 기준광은 HWP(22), 편광기(24)를 거쳐 반사 미러들(26, 28)에 의해 반사되어 코니컬 미러(30)로 조사된다. 이때 광 기록매체(32)의 상부에는 반사 미러(20)에 의해 반사된 신호광이 입사되며, 광 기록매체(32)의 하부에는 코니컬 미러(30)를 통해 광 기록매체(32) 표면에 모두 동일한 각도로 평행으로 퍼져나온 기준광이 입사된다. 따라서 이들 광 사이의 간섭으로 인해 광 기록매체(32)에는 3차원 홀로그래픽 데이터인 간섭 무늬 패턴이 기록된다. 이후 홀로그래픽 롬 시스템은 장착된 코니컬 미러(30)를 반사각이 다른 코니컬 미러로 교체한 후에 이와 같은 경로로 기준광과 신호광을 제공하여 각도 중첩 방식으로 데이터를 광 기록매체(32)인 광 디스크에 기록한다.The reference light separated by the polarization separator 16 is reflected by the reflection mirrors 26 and 28 via the HWP 22 and the polarizer 24 and irradiated to the conical mirror 30. At this time, the signal light reflected by the reflecting mirror 20 is incident on the upper portion of the optical recording medium 32, and all of the lower surface of the optical recording medium 32 on the surface of the optical recording medium 32 through the conical mirror 30. The reference light spread out in parallel at the same angle is incident. Therefore, the interference fringe pattern, which is three-dimensional holographic data, is recorded on the optical recording medium 32 due to the interference between these lights. Then, the holographic ROM system replaces the mounted conical mirror 30 with conical mirrors having different reflection angles, and then provides the reference light and the signal light through such a path, and transmits data in an angular overlapping manner to the optical disk as the optical recording medium 32. To record.

도 4는 상기 도 3에서와 같이 제조되는 DVD 호환 홀로그래픽 롬 디스크를 제조하는 본 발명의 실시 예에 따른 공정을 도시한 것으로, 본 발명에서는 디스크 본딩용 접착제를 자외선을 조사하면 경화되는 UV 경화 본드를 채용하여 잔류 모노머를 제거하는 UV 컬링 공정과 디스크 본딩 공정을 일원화시킴으로써 DVD 호환 홀로그래픽 디스크 제조 공정을 간략화 시키게 된다.FIG. 4 illustrates a process according to an embodiment of the present invention for manufacturing a DVD compatible holographic ROM disk manufactured as in FIG. 3. In the present invention, a UV curing bond that is cured by irradiating UV light on an adhesive for bonding a disk is illustrated. By employing the UV culling process and the disc bonding process to remove the residual monomers, the DVD-compatible holographic disc manufacturing process is simplified.

즉, 본 발명에서는 상기 도 4의 (a)에서 보여지는 바와 같이 코니컬 미러(conical mirror)(200)를 이용하여 홀로그램 데이터의 복제를 수행한 후, 도 4의 (b)에서 보여지는 바와 같이 UV 경화 본드층(400)을 이용하여 반사층(102)을 포함하는 상부 서브스트레이트층(100)를 홀로그램 데이터 복제가 수행된 디스크와 적층시킨 후, 홀로그래픽 디스크내 포토폴리머층(108) 상으로 자외선(202)을 조사함으로써, 자외선에 의해 디스크 내부의 기록물질인 포토폴리머층(108)에 잔류하는 모노머를 제거함과 동시에 반사층(102)을 포함하는 상부 서브스트레이스층(100)과 홀로그래픽 디스크를 본딩시켜, 도 4의 (c)에서와 같은 홀로그래픽 롬 디스크 제조를 완성시키게 된다.That is, in the present invention, as shown in (b) of FIG. 4 after the holographic data is replicated using the conical mirror 200 as shown in (a) of FIG. After laminating the upper substrate layer 100 including the reflective layer 102 with the disk on which the holographic data replication was performed using the UV curing bond layer 400, the ultraviolet ray was irradiated onto the photopolymer layer 108 in the holographic disk. Irradiating 202 removes the monomer remaining in the photopolymer layer 108 which is a recording material inside the disc by ultraviolet rays, and simultaneously bonds the holographic disc with the upper substress layer 100 including the reflective layer 102. In this way, the holographic ROM disk as shown in FIG. 4C is completed.

이때 포토폴리머층(108) 위아래에 도포된 하부 서브스트레이트층(106, 110)은 0.1∼0.2mm의 두께로 형성되고, 포토폴리머층(108)은 200∼400μm의 두께로 형성된다. 또한 상부 서브스트레이트층(100)은 0.6mm의 두께로 형성되며, 상부 서브스트레이트층(100) 하단부의 반사층(102)과 UV 경화 본딩층(400)은 수μm∼수십μm의 두께로 형성되고, 상기 상부 서브스트레이트층(100) 하단부의 반사층(102)으로부터 하부 서브스트레이트층(106, 110)으로 둘러싸인 포토폴리머층(108)으로 구성되는 홀로그래픽 디스크를 포함하는 두께는 0.6mm로 형성된다. In this case, the lower substrate layers 106 and 110 coated on and under the photopolymer layer 108 are formed to a thickness of 0.1 to 0.2 mm, and the photopolymer layer 108 is formed to a thickness of 200 to 400 μm. In addition, the upper substrate layer 100 is formed to a thickness of 0.6mm, the reflective layer 102 and the UV curing bonding layer 400 of the lower portion of the upper substrate layer 100 is formed of a thickness of several μm to several tens of μm, The thickness including the holographic disk composed of the photopolymer layer 108 surrounded by the lower substrate layers 106 and 110 from the reflective layer 102 at the bottom of the upper substrate layer 100 is 0.6 mm.

상기한 바와 같이 본 발명에서는 종래 홀로그래픽 디스크 복제 공정(1), 자외선 조사를 통한 모노머 제거공정(2) 및 본딩 공정(3)으로 이루어지는 3단계 DVD 호환 홀로그래픽 디스크 제조공정을 홀로그래픽 디스크 복제 공정(1) 및 자외선을 이용한 모노머 제거 및 본딩 공정(2)의 2단계 공정으로 간략화 함으로써 DVD 호환 홀로그래픽 디스크 제조 공정 수를 줄여 디스크의 제조 경비를 대폭 절감시킬 수 있게 된다.As described above, in the present invention, a holographic disc duplication process of a three-step DVD compatible holographic disc production process comprising a conventional holographic disc duplication step (1), a monomer removal step (2) through UV irradiation, and a bonding step (3). By simplifying the two-step process of (1) and the monomer removal and bonding process using ultraviolet rays (2), the number of DVD-compatible holographic disc manufacturing processes can be reduced, thereby significantly reducing the manufacturing cost of the disc.
