PROXIMITY FIELD OPTICAL HEAD, PROXIMITY FIELD OPTICAL HEAD DEVICE, PROXIMITY FIELD OPTICAL INFORMATION DEVICE, AND PROXIMITY FIELD OPTICAL INFORMATION SYSTEM

摘要

In prior art proximity field optical head, a scattering body generating a proximity field and an optical head exist individually and thereby the proximity field optical head cannot be miniaturized. The proximity field optical head can be miniaturized significantly by such a constitution of a proximity field optical probe slider that a semiconductor laser, a heat dissipation member, a prism for guiding light from the semiconductor laser to the scattering body, and a photodetector element are held on a slider. ® KIPO & WIPO 2009
