    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.
