ExtremeTech has reported that Hitachi-Maxell plans to begin shipping their holographic storage media by Christmas. These first generation discs will have a capacity of 300GB.
The first holographic storage media will begin shipping by Christmas, executives at media maker Hitachi Maxell have indicated.

In an interview, Rich D'Ambrise, director of technical marketing at Maxell, said that 300-Gbyte holographic disks will begin shipping either in November or December, as InPhase Technologies, the developer of the holographic technology, said last year.

However, D'Ambrise also indicated that the company will move to a second-generation, 800-Gbyte disc in 2008, and has targeted a 1.6-Tbyte removable cartridge by 2010.
With the media alone costing $120 to $180 apiece, I probably won't be asking Santa for one of these holographic drives. If you'd like to read more, the entire article can be found here.
