A method of magnetizing an erasing head for small type tape recorders is disclosed. An erasing head having its opposite ends formed in at least one convex surface is disposed in a space formed between at least two opposed electromagnetic poles. That surface of the electromagnetic pole which is opposed to the convex surface of the erasing head is made concave which corresponds in curvature to the convex surface of the erasing head such that a tangential direction of a tape travelling movement is perpendicular to a direction of a magnetic flux of the erasing head. In addition, a center axis of the erasing head is mechanically aligned with a center axis common to both the opposite electromagnetic poles by means of a jig such that a widthwise direction of a tape is perpendicular to the direction of magnetic flux of the erasing head. |
