Abstract

본 발명은 브이씨알(VCR), 디에이터(DAT), 그리고 캠코더(CAMCODER)등의 자기기록재생기의 자기 헤드에 관한 것이다. 종래에는 헤드폭이 일정하게 형성되어 있으므로 재생시에도 헤드폭과 트랙폭이 동일하게 됨으로써 재생동작시의 트랙킹 동작이 원활하지 못한 문제점이 있었다. 본 발명은 메인 헤드(31)의 적어도 일측면에 보조 헤드(32)(또는,(32)(32'))를 부착하고, 상기 메인 헤드(31) 및 보조 헤드(32)또는,(32)(32'))에 코일(31A),(32A)(또는,(32A),(32'A))을 각각 권회하여, 기록시에는 테이프(T)의 트랙폭에 해당되는 폭만큼 헤드를 사용하고, 재생시에는 테이프(T)의 트랙폭 보다 넓은 폭으로 헤드를 사용함으로써 재생시의 트랙킹 동작을 보다 원활하도록 한 것이다.The present invention relates to a magnetic head of a magnetic recorder such as VCR, DAT, and camcorder. In the related art, since the head width is formed to be constant, the head width and the track width become the same even during playback, so that the tracking operation during the playback operation is not smooth. The present invention attaches an auxiliary head 32 (or 32, 32 ') to at least one side of the main head 31, and the main head 31 and the auxiliary head 32 or 32. Coil 31A, 32A (or 32A, 32'A) is wound around (32 '), and the head is used by the width corresponding to the track width of tape T for recording. At the time of playback, the head is used with a width wider than that of the tape T to make the tracking operation during playback more smooth.
