PROBLEM TO BE SOLVED: To provide an optical memory head capable of reducing an optical propagation loss and performing reproducing with a high density and good S/N, a recording medium, and an optical memory device. SOLUTION: This optical head is provided with a light source 131, and a transmission line structure 101 having a very small structure in a tip 106, for transmitting a light emitted from the light source 131, and a part of the transmitted light is leaked at the tip 106 to form a resonator with a part of a recording medium 102. Thus, light modulation efficiency depending on the presence of the information of the recording medium 102 is increased, and by using a photodetector 134 to detect a reflected light from the transmission line 101, the optical head of a reflection type is obtained. |
