Holographic storage uses a patented two-chemistry Tapestry photopolymer write-once material. The recording material is 1.5 mm thick and is sandwiched between two 130 mm diameter transmissive plastic substrates. Last year, InPhase indicated that the first incarnation of the InPhase technology would be used for archival purposes, and D'Ambrise indicated that that will still be the case: media will be roughly $120 to $180 apiece, and drives will cost about $15,000.
Holographic storage to arrive in December
