Late last week, TDK demonstrated its technological prowess by displaying the prototype of a new optical disc that can hold 1 TB of data. The unnamed disc type holds data on both its sides, each with 16 recording layers, each layer holding 32 GB of data. Physically, the disc has the same diameter as today's CDs, DVDs, and Blu-ray discs at 12 cm, but is said to have double the thickness of a Blu-ray disc. It uses the same materials used in making Blu-ray discs, and also uses the same numerical aperture value of 0.85, which indicates that a player of this new medium should be able to read Blu-ray discs, too.
