摘要：
A near-field optical memory head for recording and/or reproducing information of a recording medium by utilizing near-field light
wherein near-field light forming means having a very small aperture portion (54) for forming near-field light on the recording medium and near-field light detecting means (56) for detecting the formed near-field light are provided on a same substrate (52) and the substrate is constituted to project from a substrate at an outer peripheral portion.
