Nanotechnology for 4TB DVDs




DVDs are far from useless even now, despite what some analysts would have people believe, which is why we feel that it isn't a waste to use nanotechnology on them.

A team of scientists from National Chiao Tung University (NCTU) in Taiwan, and Swinburne University of Technology (SUT) in Australia, have come up with something interesting. Basically, it is a nanotechnology-based scribing procedure that can store 4 TB of DATA on a DVD-ROM disk.

4TB is clearly beyond even the most advanced BDXL disks (Blu-ray extra-large capacity), which come in 100 GB (triple-layer) and 128 GB (quad-layer). Then again, the nanotechnology is usable on Blu-ray disks too. With data density going from 1.1 Tb (Terabits) to 2.75, BD capacity (considering the multi-layer design) could improve by a factor of 80.
