description PROBLEM TO BE SOLVED: To provide a compact and large-capacity hard disk device. SOLUTION: A head part 3A constituting the hard disk device is provided with a light-transmitting/receiving board 11 provided with a VCSEL 111 and a photodetector 112; and a probe 131 having an opening part 131a generating near field light, based on light rays emitted from the VCSEL 111. Cores 121, 122 being an optical waveguide 12B for guiding the light rays emitted from the VCSEL 111 to the opening part 131a of the probe 131 and guiding light rays that entered from the opening part 131a to the photodetector 112 are provided integrally with a probe slider 13, in which an air lubricating plane 134 is formed at a plane, provided with the opening part 131a in between the light-transmitting/receiving board 11 and the probe slider 13.
