Abstract

본 발명은 자기 헤드를 구성하는 소재로서 Mn-Zn 단결정 페라이트와 Mn-Zn 다결정 페라이트와 Mn(또는 Zn) 단결정 페라이트를 이용하여 종래의 단순 또는 복합 자기 헤드가 갖는 결점을 해소한 복합 자기 헤드 및 그 제조 방법에 관한 것이다.The present invention provides a composite magnetic head which solves the shortcomings of a conventional simple or composite magnetic head by using Mn-Zn single crystal ferrite, Mn-Zn polycrystalline ferrite, and Mn (or Zn) single crystal ferrite as a material of the magnetic head. It relates to a manufacturing method.

본 발명에 따른 복합 자기 헤드는, 자기 기록 매체와 접촉하는 접동면(15)을 갖는 복합 자기 헤드의 상부를 형성하면서 Mn-Zn 단결정 페라이트로 이루어진 제1자성체와, 복합 자기 헤드의 하부를 형성하면서 Mn-Zn 다결정 페라이트로 이루어진 제2자성체, 및 상기 제1자성체와 상기 제2자성체 사이에 구비되며, 구성성분이 상기 제1자성체와 상기 제2자성체의 주성분과 동일하고 또한 결정구조가 상기 제1자성체의 결정구조와 동일한 제3자성체로 이루어진 것을 특징으로 한다.The composite magnetic head according to the present invention forms a top portion of a composite magnetic head having a sliding surface 15 in contact with a magnetic recording medium, and forms a first magnetic body made of Mn-Zn single crystal ferrite and a lower portion of the composite magnetic head. A second magnetic body made of Mn-Zn polycrystalline ferrite, and between the first magnetic body and the second magnetic body, the component is the same as the main component of the first magnetic body and the second magnetic body and the crystal structure is the first It is characterized by consisting of a third magnetic body that is identical to the crystal structure of the magnetic body.

본 발명에 따른 복합 자기 헤드는 재생출력의 안정성과 재현성이 우수하며 고밀도로 기록을 행할 수 있고, 수명이 연장된다.The composite magnetic head according to the present invention is excellent in the stability and reproducibility of the reproduction output, can record at a high density, and the life is extended.
