Claims (1)
- 투명기판상에 보호층을 형성하고 그 위에 기록층, 보호층 및 반사층을 차례로 형성하여 구성되는 광자기 기록매체 중에서 기록층 형성 전후 과정에 형성되어서 기록층을 보호하는 실리콘 질화물 박막의 보호층을 형성하기 위해, 통상의 스퍼터링 장치내에서 실리콘 타케트에 대해 교류(RF) 또는 직류(CD) 전원을 가동시키고 아르곤가스의 질소가스를 함께 유입시키면서 반응 스퍼터링 방법으로 실리콘 질화물 박막을 형성시켜서 광자기 기록매체를 제조함에 있어서, 상기 기록층 형성의 전후 과정에서 각각 형성되는 보호층인 실리콘 질화물 박막의 형성시에 스퍼터링 장치의 진공조내로 유입되는 질소가스 유입량을 3~10SCCM 범위에서 일정하게 유지시킴과 동시에 아르곤가스의 유입량은 0~100SCCM 범위내에서 변화시키면서 스퍼터링시켜서 실리콘 질화물의 굴절율을 조절하여 실리콘 질화물 박막의 보호층을 형성하는 것을 특징으로 하는 광자기 기록매체의 제조방법.
