NEAR-FIELD OPTICAL HEAD, NEAR-FIELD OPTICAL HEAD DEVICE, NEAR-FIELD OPTICAL INFORMATION DEVICE, AND NEAR-FIELD OPTICAL INFORMATION SYSTEM

摘要

A conventional near-field optical head cannot be miniaturized because a scattering body generating a near field and an optical head exist individually. A near-field optical head capable of being significantly miniaturized is constituted by a near-field optical probe slider formed by holding, on a slider, a semiconductor laser, a heat dissipation member, a prism for guiding light from the semiconductor laser to a scattering body and a photodetector element.
