Today, we are in a position to achieve even greater data densities on discs through the use of blue lasers which have shorter wavelengths than red ones. The new optical engineering technique is used in HD-DVDs and Blu-ray discs with storage capacities of 15 to 100 gigabytes, as these are the only ones that can fully satisfy the digital data requirements of high-definition TV.
But researchers at Bayer MaterialScience are already working with partners such as InPhase Technologies in the USA on holographic storage media (manufacturing partner: Maxell) which are set to continue the revolution in digital data discs. The new disc type – called TapestryTM – has a capacity of 300 gigabytes and is currently in its test phase. Unlike a conventional CD or DVD, data is no longer written and read bit by bit, but stored in the form of holograms, i.e. in entire data blocks all at once. This means that the read/write process can be accelerated many times over.
