Two-dimensional near field optical memory head

摘要

Disclosed is an optical memory head in which a vertical cavity surface emitting laser array constituted by laying out, in a matrix form, a large number of vertical cavity surface emitting laser elements each having a laser output part with an ultra fine hole as an output window for emitting evanescent light is arranged such that the layout direction of the laser element is inclined with respect to the tangential direction to rotation of an optical recording medium at a fine angle.
