Abstract
Provided is a highly reliable optical recording head which has a small fluctuation of a quantity of light applied on a recording medium due to temperature. The optical recording head is provided with a light guide section for guiding light applied from a light source, a slider relatively moving to the recording medium, and a light transmitting section, which is arranged on the slider, transmits the light outputted from the light guide section and outputs the light toward the recording medium. The optical recording head is further provided with an adhesive layer, which is sandwiched between the light transmitting section and the light guide section and fixes the positions of the light transmitting section and the light guide section, and an elastic cohesive layer, which is sandwiched between the portions other than the light transmitting section of the slider and the light guide section.
