Claims (6)

  1. 반사층과 제1기록층이 형성된 투명기판에 제2기록판을 갖는 수지층이 형성된 광 기록매체의 제조방법에 있어서, 상기 반사층과 기록층이 형성된 투명기판과 그 상면에 기록층을 갖는 스템퍼를 상호 소정의 간격으로 유지시키는 제1단계와, 상기 소정간격 이격된 투명기판과 스템퍼의 중앙에 형성된 관통공의 적어도 일측을 차단하고 타측의 관통공을 통하여 상기 투명기판과 스템퍼 사이로 수지를 가압하여 공급하는 제2단계와, 상기 수지의 공급이 완료된 후 상기 관통공에 잔존하는 수지를 제거하여 관통공을 관통시키는 제3단계를 구비하여 구성된 것을 특징으로 하는 광 기록 매체의 제조방법.
  2. 각각 반사층과 제1기록층이 형성된 투명기판상에 제2기록면을 갖는 수지층을 형성하는 광 기록매체의 제조장치에 있어서, 상호 대향되도록 설치되며 대향되는 상기 투명기판과 스템퍼가 고정되는 고정부가 각각 마련되고, 각 중앙부에 투명기판과 스템퍼의 중앙에 형성된 관통공과 연통되는 연통공이 형성된 상부금형 및 하부 금형과, 상기 하부금형의 관통공에 소정의 승강수단에 의해 슬라이딩 가능하게 설치된 펀치부재와, 상기 상부금형의 관통공에 설치되는 수지공급수단을 구비하여 된 것을 특징으로 하는 광 기록 매체의 제조방법.
  3. 제2항에 있어서, 상기 상하부 금형 가장자리의 적어도 일측에는 상기 수지공급수단으로부터 공급된 수지가 노출되는 것을 차단하는 수지차단수단이 더 구비된 것을 특징으로 하는 광 기록 매체의 제조방법.
  4. 제2항에 있어서, 상기 상부금형이 투명한 재질로 이루어진 것을 특징으로 하는 광기록 매체의 제조장치.
  5. 제2항 내지 제4항중 어느 한 항에 있어서, 상기 상부금형의 상부에 광을 조사하여 수지를 경화시키는 광원을 구비하여 된 것을 특징으로 하는 광 기록 매체의 제조방법.
  6. 제3항에 있어서, 상기 수지차단수단이 상기 상부금형의 가장자리로부터 수직하방으로 연장되는 둘레턱을 구비하여 된 것을 특징으로 하는 광 기록 매체의 제조방법.
