Abstract

본 발명은 불순한 가스의 출현을 억제하고 마그네틱층과 보호막의 경계에서 발생하는 수평방향(in Plane) 성분을 지닌 히스테리시스 킹크(Hysterisis Kink)에 영향을 미치는 성분의 출현을 방지하여 CNR을 증가시키고 마그네틱 감도를 높힐 수 있게한 것에 목적을 둔 것이다.The present invention suppresses the appearance of impure gases and prevents the appearance of components affecting the hysteresis kink with in-plane components occurring at the boundary between the magnetic layer and the protective film, thereby increasing the CNR and increasing the magnetic sensitivity. The purpose is to make it possible to raise the level.

상기와 같은 목적을 가진 본 발명은 기판(1) 위에 불순한 가스의 출현을 억제하도록 증착한 NbCrZr층(2)과, 상기 NnCrZr층 위에 적층한 제1SiNx층(3)과, 상기 제1SiNx층 위에 증착한 제1Cr층(4)과, 상기 제1Cr층위에 기록막으로 적층한 마그네틱층(5)과, 상기 마그네틱층 위에 증착한 제2Cr층(6)과, 상기 Cr층 위에 적층한 제2SiNx층(7)과, 상기SiNx층위에 적층시킨 AlTi층(8)으로 이루어진 것이다.The present invention having the above object has a NbCrZr layer (2) deposited to suppress the appearance of an impure gas on the substrate (1), a first SiNx layer (3) laminated on the NnCrZr layer and the first SiNx layer deposited on A first Cr layer 4, a magnetic layer 5 laminated on the first Cr layer as a recording film, a second Cr layer 6 deposited on the magnetic layer, and a second SiNx layer laminated on the Cr layer ( 7) and an AlTi layer 8 laminated on the SiNx layer.
