    • A composite magnetic head includes a read/write head section of a number of thin film or bulk read/write heads joined such that respective head gaps are aligned at predetermined intervals in the widthwise direction of tracks of a recording medium. An erase head section of a plurality of bulk heads respectively corresponding to the thin film or bulk read/write heads is joined to the read/write section through a magnetic shielding member, such that respective erase head gaps are aligned at predetermined intervals in the widthwise direction of the recording medium tracks. The read/write head section and the erase head section are joined in the longitudinal direction of the tracks such that the read/write head gaps and the erase head gaps of the respective sections are relatively close to each other, and the recorded data can be completely erased notwithstanding azimuth and spacing losses.
    • 复合磁头包括多个薄膜或大容量读/写头的读/写头部分,其连接成使得相应的头部间隙在记录介质的轨道的宽度方向上以预定间隔对齐。 分别对应于薄膜或大容量读/写头的多个散装头的擦除头部分通过磁屏蔽构件连接到读/写部分,使得相应的擦除头间隙在宽度方向上以预定的间隔对准 记录介质轨迹的方向。 读/写磁头部分和擦除磁头部分在磁道的纵向连接,使得各部分的读/写磁头间隙和擦除磁头间隙相对靠近,并且记录数据可以是 即使方位角和间距损失也完全消失。
