ABSTRACT:
A multi-channel dual-gap magnetic head. The head has a plurality of magnetic head tips which are separated magnetically from each other by non-magnetic materials, and each having two magnetic gaps. A plurality of magnetic back cores are connected to said magnetic head tips, and a plurality of windings are wound on the respective back cores. The corresponding magnetic gaps in the head tips are aligned in two straight lines which are parallel to each other and perpendicular to the direction of tape movement of the tape for a recording and reproducing device. The magnetic gaps aligned in one straight line have at least two different gap widths for carrying out different functions from among the functions of recording, playback and erasing.
