Breakthrough in nano storage research

Staff writer, with CNA

A new type of nanotechnology developed by research teams at National Chiao Tung University (NCTU) in Taiwan and Swinburne University of Technology (SUT) in Australia could at least double data-storage density, NCTU said yesterday.

The new technology has improved data storage density from 1.1 terabits (Tb) per cubic centimeter to 2.75Tb, which would allow a Blu-ray dual-layer DVD-ROM to store 80 times its original capacity, Allen Lan (藍子翔), a postdoctoral researcher at NCTU, said at a press briefing.

A DVD-ROM using the new technology would be able to store 4 terabytes (TB) of data, said Lan, who went to Australia last year and worked with a team led by professor Gu Min (顧敏), director of SUT’s Centre for Micro-Photonics.

One TB is equal to 1 trillion bytes, or 1,000 gigabytes (GB). A 50GB Blu-ray DVD can store an eight-hour-long HD movie or about 10,000 MP3 songs.

The research project represents a breakthrough in the development of 3D polarization engineering in nano-optics, said Tien Chung-hao (田仲豪), an associate professor of photonics who supervised Lan during the project.

In addition to optical storage, Tien said he hoped to apply the concept to producing semiconductors and imaging molecules in 3D.

The results of the study were published on the Web site of the international scientific journal Nature Communications on Aug. 14.
