ABSTRACT:
A rotational magnetic head apparatus comprises a fixed drum, a rotational drum mounted rotatably about the same axis as that of the fixed drum and having an opening formed on the end surface of the rotational drum facing the fixed drum, and a magnetic head provided in the opening. A tape is wound partly around the outer periphery of the fixed and rotational drums so that the tape is caused to travel while the magnetic head slides on the magnetic tape. The position of the magnetic head is selected to be in the center between the opposing surface of the opening facing the fixed drum and the opposing surface of the fixed drum.
