Holographic disk media answers the need for optical mass storage that rivals the size of hard disks today. By squeezing 500 Gbytes of data onto a single DVD-sized disk, GE plans to cash in on a market that is begging to be served. Look for holographic disks to begin making a big splash within three years by early adopters with gaping backup needs, and to be on everybody's desktop within five to seven years. R.C.J.
GE Global Research reports that is has succeeded in writing patterns on holographic disks that brighten their reflectivity by up to 200 times, enabling next-generation holographic disks that could store up to 500 Gbytes, or about 10 times the storage capability of Blu-ray video disks. Optical disk drives with vastly more data storage than current storage media promise to harness the third dimension to write holographic patterns. GE estimates that its 500-Gbyte disk drives will be available by late 2011, using media that costs about 10 cents/gigabyte compared to 50 cents/gigabyte for current Blu-ray media.
