ABSTRACT:
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.
