Sony is all set to bring next wave of revolution in the history of data storage. The Japanese electronics giant has announced that it will release a multi-layer optical disk that can store more than 500GB data.
The holographic recording technology, on which Sony is working now, will have seven layers and produce standard-sized 12cm disks with the capacity of storing 500GB data of any kind. I mean from HD Video to computer data.
The multi-layer holographic disk will be available in the next three years. Sony is using its ‘Micro-Reflector’ method to write to seven layers per disk. The memory density per layer is 1.2 GB and the maximum error rate is 4.1 × 10-4.
The upcoming Sony holographic recording technology records data on discs in the form of laser interference fringes empowering existing discs the same size as today’s DVDs to store as much as one terabyte of data with a transfer speed of one gigabyte per second.
