Abstract

본 발명은 자기헤드 및 그 제조방법에 관하여 개시한 것이다.The present invention relates to a magnetic head and a method of manufacturing the same.

본 발명 자기헤드 및 제조방법은 적층형 자기헤드의 자성막을 FeRuGaSi와 FeIrGaSi 및 FeTaN 등과 같은 자화열처리 효과가 뛰어난 재료로 형성하고, 자장열처리를 통해 자화시켜 상기 I-코어의 자성막은 길이방향으로 자기이방서을 가지며, 상기 C-코어의 자성막은 폭방향으로 자기이방성을 가지도록 함으로써, 자기헤드 내의 자속흐름이 개선되어 디지탈방식의 고밀도 기록재생 등에 적합하도록 자기헤드의 기록재생 효율을 향상시킬 수 있게 한 것이다.In the magnetic head and the manufacturing method of the present invention, the magnetic film of the laminated magnetic head is formed of a material having an excellent magnetization heat treatment effect such as FeRuGaSi, FeIrGaSi, FeTaN, and the like, and magnetized by magnetic field heat treatment so that the magnetic film of the I-core has a magnetic anisotropy in the longitudinal direction. The magnetic film of the C-core has magnetic anisotropy in the width direction, thereby improving the magnetic flux flow in the magnetic head, thereby improving the recording and reproducing efficiency of the magnetic head so as to be suitable for digital high-density recording and reproduction.
