Claims (1)

강자성 산화물로 된 자기 코어부와, 이 자기 코어부에 자기 기록 매체 대접면에서 자기 갭 형성면에 대하여 소정 각도로 경사하도록 피착되는 강자성 금속박막으로부터 자기 코어 반폭체가 구성되고, 상기 강자성 금속 박막끼리를 대략 일직선상으로 맞대게 함으로써 자기 갭이 구성되게 되는 자기 헤드에 있어서, 한쪽의 자기 코어 반쪽체에 형성되는 강자성 금속 박막의 자기 갭 형성면에 있어서의 폭을 트랙폭과 똑같이 하고, 다른쪽의 자기 코어 반쪽체에 형성되는 강자성 금속박막의 자기 갭 형성면에 있어서의 폭을 트랙폭보다 크게 한 것을 특징으로 하는 자기 헤드.A magnetic core half-width body is formed from a magnetic core portion made of ferromagnetic oxide and a ferromagnetic metal thin film deposited such that the magnetic core portion is inclined at a predetermined angle with respect to the magnetic gap forming surface at the magnetic recording medium contact surface. In a magnetic head in which a magnetic gap is formed by abutting in a substantially straight line, the width of the magnetic gap forming surface of the ferromagnetic metal thin film formed on one magnetic core half is equal to the track width, and the other magnetic A magnetic head characterized in that the width of the ferromagnetic metal thin film formed on the core half body on the magnetic gap forming surface is larger than the track width. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
