The availability of Holographic storage drives for your home PC came a step closer when InPhase announced that it had developed the world's first prototypes of Holographic storage devices. InPhase said that these prototype drives will be the first of a range of Tapestry holographic drives, offering capacities that range from 200 GByte to 1.6 TByte on a single disk. The current prototype is just that - a prototype, and InPhase has not yet commented on commercial availability and pricing of the drives. But it does give some indication of what the storage of the future PC might well be.
At the heart of the system is a holographic read/write head is the heart of the drive technology. According to InPhase, recently available 407 nm blue lasers available in other optical devices such as Blu-ray provide the wavelength required for high capacity holographic storage.
