Claims (3)

  1. 정보 캐리어와 협동하는 헤드 훼이스를 가진 박막 자기 헤드로서, 박막 자기 헤드는 헤드 훼이스와 인접한 제1 및 제2플럭스 도체와 헤드 훼이스로부터 떨어진 자기-저항 소자를 가진 자기 요크를 구비하며, 자기-저항소자는 그 제1엣지부가 제2엣지부 보다 헤드 훼이스에 더 근접하며 헤드 훼이스에 평행하게 연장하는 용이한 자화의 축을 가지며, 자기-저항 소자는 헤드 훼이스와 직각 방향으로 연장하고, 제1플럭스 도체는 적어도 제2엣지부쪽으로 연장하며 제2플럭스 도체는 적어도 개략적으로 제1엣지부쪽으로 연장하며, 박막 자기 헤드는 또한 헤드 훼이스와 평행하게 연장하는 용이한 자화의 축을 가진 추가의 자기-저항 소자를 구비하는 박막 자기 헤드에 있어서, 추가의 자기-저항 소자는 자기 요크의 일부분을 형성하며 헤드 훼이스에서 제1및 제2플럭스 도체사이에 배치되는 것을 특징으로 하는 박막 자기 헤드.
  2. 제1항에 있어서, 자기-저항 소자 및 추가의 자기-저항 소자는 각각 전기 전도성 연결 트랙을 거쳐 상호 연결된 한 단부를 가지며 상기 단부는 용이한 자화의 축의 단부와 일치하며, 상기 소자들은 용이한 자화의 축의 다른 단부와 일치하는 소자의 다른 단부에 의해 전기 전도성 연결 트랙에 각각 연결되는 것을 특징으로 하는 박막 자기 헤드.
  3. 제1항 또는 2항에 있어서, 바이어스 권선은 자기-저항 소자중 적어도 하나에 근접하고 평행하게 연장하는 것을 특징으로 하는 박막 자기 헤드.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
