摘要 PROBLEM TO BE SOLVED: To heat the vicinity of a magnetic flux generated from a curved main magnetic pole only with near-field light.SOLUTION: A recording element 21 having an auxiliary magnetic pole 30, a coil 33, an insulator 34, a main magnetic pole 32, a magnetic shield 35 and a near-field light generating element 50 formed from a slider substrate 20 side in this order is fixed to a slider tip surface. The insulator has a shape with a protrusion on a position where the coil exists and with a recess where the coil does not exist with a predetermined curvature. When the main magnetic pole is formed on the insulator with this kind of shape, a curved main magnetic pole is formed. Furthermore, the near-field light generating element is formed on the main magnetic pole curved in such a way. Also a light coupling part 50c to couple a luminous flux L from an optical waveguide 4 to the near-field light generating element is provided on a part of the near-field light generating element. Because a disk D side end face of the near-field light generating element and the light coupling part are separated from each other with a predetermined distance, only near-field light R generated from the near-field light generating element is made to come very close to a recording magnetic field generated from the main magnetic pole.
