Abstract:
A recording head includes a slider, and a recording element fixed to a side surface of the slider on the side of an outflow end and having a main magnetic pole and an auxiliary magnetic pole which generate a recording magnetic field. A spot light generating element includes a core having a reflecting surface that reflects a luminous flux introduced from one end side to the other end side in a direction different from the direction of introduction and a luminous flux condensing unit configured to generate a spot light by propagating the reflected luminous flux to the other end side while condensing the same, and a clad configured to confine the core in the interior thereof. The spot light generating element is fixed adjacently to the recording element in a state in which the other end side is faced toward a magnetic recording medium. A luminous flux guide is arranged in parallel with the slider and allows the luminous flux to be introduced from the one end side into the core whereby the luminous flux condensing unit generates a spot light in the vicinity of the main magnetic pole.
