Abstract
Near-field light is generated from a fine opening formed in a silicon substrate to thereby record information on a recording layer of a recording medium. When the information is read out, reflected light from the recording layer is detected by a photodiode. The photodiode is formed by providing a boron-implanted layer around the fine opening in the silicon substrate. The detection signal of the reflected light is derived from the electrode. By this photodiode, the reflected light for reading is efficiently detected.
