Sony develops holographic disks to store 500GB |
Data storage news just keeps moving forward. Sony has announced that it will release a multi-layer optical disk that can store over 500GB data.
They are working on it now and the holographic recording technology will have seven layers, producing standard-sized disks with the ability to store 500GB of data of any kind, from HD Video to computer data. They expect the holographic disk to be available sometime in the next 3 years. They are using their “Micro-Reflector” method in order to write to seven layers per disk. Memory density per layer is 1.2 GB and the maximum error rate is 4.1 × 10-4.
The new holographic recording technology records data in the form of laser interference fringes giving discs the same size as today’s DVDs the ability to store as much as one terabyte of data with a transfer speed of one gig per second.
I’m curious to see just how far Sony and others can push this, and how quickly. Very fascinating “Space” race.

i remember hearing about a disc that could hold over a terabyte that was in prototype stages a few years ago..
this isn’t it but its certainly getting closer..
when i first heard the idea of one disc holding over a terabyte, i just laughed, but with this news, it seems more possible than it did back then.
