A magnetic head for recording and reproducing data, on and from a flexible magnetic disk, is supported by a support mechanism. The support mechanism is capable of rotating the head around the first axis extending in a radial direction of the disk, and applies a pressing force to the head. The head has leading and trailing edges. The head includes a flat surface opposing the disk and having a leading and trailing ends, and a midpoint between thereof. A second surface connects the trailing edge to the trailing end of the flat surface. The distance between the trailing edge and the disk is longer than the distance between the trailing end of the flat surface and the disk. Magnetic gaps are arranged on that portion of the flat surface which is located between the midpoint and the trailing end thereof. When the disk is rotated at a predetermined speed and the support mechanism applies a predetermined pressing force to the head, an air bearing force is generated and acts on the flat surface. Thus, the head is slightly rotated around the first axis such that the leading end moves away from the disk and the trailing end is pressed onto the disk. That portion of the flat surface can contact the disk, so that the magnetic gaps are located sufficiently close to the disk.
