PURPOSE:To adhere the head on a disc, by performing the constitution so that the three sliding surfaces are located on the head, one at the front end and two at the rear end toward the rotation direction, one of the rear end surfaces is provided with the read/write and erasing magnetic gap, and the head is depressed on a disc with the two rear end sliding surfaces. CONSTITUTION:The sliding surface 18 is placed at the tip of the holder 16 of the head 15, and two sliding surfaces 18 are provided at the rear end. The surface 18 has a stepped part to the surface 17, the surface 5 is provided with plate spring so that the two rear end sliding surfaces 18 can closely be contacted on a disc when depressed on a flexible disc. One of the sliding surfaces at the rear end is provided with the read/write magnetic gap 9 and the erasing magnetic gap 13. The center of depression to the three sliding surfaces is the centroid of a triangle tying the sliding surfaces 18 or biased to the gaps 9 and 13. Thus, the adhesion of the head 15 with the disc can be improved. |
