A magnetic head has a left side rail formed on a disk facing surface in a protruded manner, and a right side rail formed on the disk facing surface in a protruded manner. A cross rail formed on the disk facing surface protrudes and is elongated continuously to both the left side rail and the right side rail. A left air bearing surface is formed on the disk facing surface in a protruded manner, and formed only on a side of a leading edge continuously from the left side rail. The left air bearing surface has a continuous portion to the left side rail, and a right air bearing surface which is formed on the disk facing surface in a protruded manner, formed only on a side of the leading edge continuously from the right side rail. The left air bearing surface has a continuous portion to the right side rail, wherein a recessed portion is constructed on the disk facing surface so as to be surrounded by the left side rail the left air bearing surface, the cross rail, the right air bearing surface, and the right side rail.
