Description

복합형 자기헤드Hybrid Magnetic Head

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제 1 도는 본 발명에 의한 복합형 자기헤드의 구조를 나타낸 개략 종단면도,1 is a schematic longitudinal sectional view showing the structure of a hybrid magnetic head according to the present invention;

제 2 도 및 제 3 도는 본 발명에 의한 비대칭의 개선의 효과를 나타낸 그래프.2 and 3 are graphs showing the effect of improving asymmetry according to the present invention.

Claims (1)

기록재생용 갭을 가지는 기록재생코어와, 상기 기록재생용 갭에 의하여 기록된 트랙의 양단부를 소거하는 소거 갭을 가지는 소거코어를 비자성재료를 개재시켜 일체화시킨 복합형 자기헤드에 있어, 상기 기록 재생코어와 소거코어의 벡코어를, 양코어에 공통으로 하여, 상기 양 갭의 반대측에 설치한 것을 특징으로 하는 복합형 자기헤드.A composite magnetic head in which a recording and reproducing core having a recording and reproducing gap and an erasing core having an erasing gap for erasing both ends of a track recorded by the recording and reproducing gap are integrated through a nonmagnetic material. A hybrid magnetic head comprising a back core of a regeneration core and an erasing core common to both cores, and arranged on opposite sides of the gap. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
