GE creates 500GB holographic storage disc


It seems that every other month someone’s coming out with the prototype of a disc that can store X times more than a DVD/Blu-ray. I was actually thinking of making one myself with a stack of blank BDs and some blu-tac but then GE put together a method of storing 500GB using holographic disc storage which is much more interesting.

Instead of etching 2D patterns into the surface, holographic technology uses a three dimensional process with the disc acting like a maze of microscopic mirrors giving a depth to the optical layer where all the data is stored. GE expects them to be introduced by 2012 but the real key is, of course, how expense they will be.

Blu-rays began as $1 per GB when they first came out dropping to something closer to half that today. GE hopes these holographic discs will be 10 cents per GB, so a much more affordable $5 for the whole thing.

The thing I can’t help wondering, though, is whether there’s really a viable future in optical storage? Between SSDs and cloud computing, I was hoping to rid myself of discs by 2012.

Pioneer on a roll, develops 500GB optical disc

pioneer_16layer_disc.jpgOnly last month we were heralding Pioneer’s development of a 400GB optical disc, and just a month later its researchers have popped on another four layers and 100GB of storage to create a half terabyte disc.

In actual fact, to be fair, Pioneer has simply confirmed the “viability” of such a disc, which may or may not exist in a laboratory somewhere. The company believes that the technology, based on the same techniques used to make current 25GB and 50GB Blu-ray discs, is easier and cheaper to produce than holographic discs…

Brits still like music CDs despite rise in Internet downloads

cd_rack.jpgWe’re still an nation who likes our CD collections, according to recent figures from the British Phonographic Industry.

Despite the rise in popularity of music downloading (both legal and not), nearly half of the people recently surveyed by PlusNet said that they thought it would be at least ten years until the CD becomes obsolete, with one n ten saying that the format would never die.
