The goal is to establish nano-terabyte storage technology. Technical breakthrough for current DVD (4.7GB) and HD-DVD (20-25GB) enables the capacity to reach 100 GB~1000 GB. The major principle is to achieve storage capacity up to 1 terabyte by using near-field optics and fine aperture (50nm) to generate writable optical spot (<100nm). In addition, the goal is attained by developing nanoprobe field, which can generate electron beam for writing technology. To fulfill the objective in nanoscale recording technology, it has to develop the optical disk technology like nano scale optical-writing magnetic-reading and Super-RENS, and servo control technology and weak signal detection etc.
Currently, based on the established R&D capability for the key parts and modules of DVD the development of HD-DVD core technology is under way. Sub-Terabyte/Terabyte R&D is also beginning to be carried out, which includes nanoscale optical head technology, nanoprobe and actuator technology, nanolithography, nanotechnology for optical storage media, and nanoscale servo control technology etc.
