A method for manufacturing a magnetic head includes the process by which a curved sliding surface of a head chip for making contact with a recording medium and a penetrating window of a side surface of the head chip for determining a gap depth are formed by machining the head chip using a laser beam. The method includes placing the head chip on a working stage; placing a first mask in a light path of a laser beam from a laser source toward the side surface, the first mask being provided with a first slit for the purpose of forming the curved sliding surface of the head chip and a second slit for the purpose of forming the penetrating window of the side surface of the head chip; and irradiating the side surface through the first and second slits with the laser beam, thereby forming the curved sliding surface and the penetrating window in the head chip. The method also may include forming track grooves by irradiating the sliding surface of the head chip with the laser beam.
