Abstract

Data-storage using near-field optical microscopy is a promising technology for the breakthrough of high-density optical disk memory since wavelength limit of conventional lens-optics is not applied. We have proposed a MEMS for the near-field optical data storage, which consists of integrated optical micro-probes and a micro media-translation-table. Three-dimensional lithography based on the bulk micromachining using resist spray coater is applied to the integration of waveguide, micro-pinhole tip, cantilever, and photodiode for the MEMS probes. The media-translation-table consists of the inverted scratch drive actuators (inverted SDAs) fabricated by surface micromachining.
