Energy-Beam Nano-Fabrication Technology
Ultra-high Density Optical Disc Mastering System
Technology:
Ultra-high density mastering system integrates the nano-position stage system, exposing and machining techniques, data transmitting mechanism, design of precise machinery and servo-control system to reaches the goal of ultra-high dense data recorded on a disc. Among these technologies, near-field optics and electron beam exposure techniques were adopted to record the data on a substrate. With the development of these technologies, the recording density on a disc increases greatly without the restriction of optical diffraction limit.
Characteristic:
- Near-field optics machining (the aperture size of fiber tip: 100nm)
- Electron beam recording (the spot size of electron beam: 100nm)
- Data recording density reaches 20 Gbits/in2, far beyond the conventional optical disc.

Benefits:
- Simplify the structure of mastering system
- Reduce the cost of facility
- Manufacture the DVD and HD-DVD high density optical disc stamper

Applications:
- The mastering system for optical disc stamper
- Near-field optical disc drive
