发明名称 PROXIMITY FIELD OPTICAL HEAD AND INFORMATION RECORDER AND REPRODUCER
摘要 <p>A proximity field optical head includes a slider arranged oppositely to the surface of a magnetic recording medium, a recording element having a main magnetic pole and an auxiliary magnetic pole for generating a recording magnetic field and being secured to the tip end face of the slider such that the main magnetic pole and the auxiliary magnetic pole are arranged in the longitudinal direction of the slider under a state where the auxiliary magnetic pole is located on the tip end face side of the slider, a proximity field light generation element secured contiguously to the main magnetic pole while directing the other end side toward the magnetic recording medium side, and making a light flux introduced from one end side propagate toward the other end side to generate proximity field light, and emitting that proximity field light to the outside from the other end side, and light flux introduction means secured to the slider and introducing the light flux into the proximity field light generation element from the one end side. The proximity field light generation element has a surface inclining to the optical axis of the light flux propagating internally and opposing the main magnetic pole on the other end side. A metal film for increasing the intensity of the proximity field light is formed on the inclining surface.</p>
