소재위에 강자성 금속 박막층을 형성한 자기기록매체에 있어서, 상기 강자성 금속 박막층의 표면에 수은을 접촉시켜 자성금속과 수은의 합금층을 형성하여 구성함을 특징으로 하는 자기기록매체.A magnetic recording medium having a ferromagnetic metal thin film layer formed on a material, wherein the magnetic recording medium is formed by contacting mercury on the surface of the ferromagnetic metal thin film layer to form an alloy layer of magnetic metal and mercury. 소재위에 Co, Ni, Fe등의 금속 박막층이 형성된 자기기록매체를 일정온도가 유지되는 수은조에 침적시킴으로써 수은이 금속 박막층과 접촉되게 하여 금속 박막층의 표면에 자성금속과 수은 합금층이 형성되게 하는 것을 특징으로 하는 자기기록매체의 제조방법.By depositing a magnetic recording medium having a metal thin film layer of Co, Ni, Fe, etc. on the material in a mercury tank maintained at a constant temperature, mercury is brought into contact with the metal thin film layer to form a magnetic metal and a mercury alloy layer on the surface of the metal thin film layer. A method of producing a magnetic recording medium. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
