TDK made a new technological demonstration of Blu-ray having succeeded in putting on a 12 cm wafer 12 layers of 32 GB. Even though we get this type of announcement regularly, TDK is separated here by the hardware requirement for reading and burning these media. It practically the same as found in devices currently being marketed.
Of course, the principal difficulty remains to know how to manufacture this stacking of layers; these must be rather transparent so that one can reach the intermediate layers while also being opaque enough so that one can read the data on these layers.At the moment this remains only something created in the laboratory. To interest the general public with the availability of Blu-ray media of more than 50 GB, the market needs to be saturated enough so that the need for innovation is felt. One is still very very far from this especially with the explosion of capacity of flash memory media and the fact that the majority o
