Hundred Movies On One Disk With Holographic Data Storage

Hundred Movies On One Disk With Holographic Data Storage

Holographic data storage system has the capacity to store 1 terabyte of data on a disk the size of a regular CD.

Blu-ray discs have unlocked the technology to use multiple layers within the surface of an optical disk to store extra data.

But the promise of a new holographic data storage system, will allow information to be stored holographically in three dimensions throughout the disk, unlocking even more room for your precious data.

Under development by General Electric, the new holographic data storage is expected to hit the shelves around 2012.

Not the first holographic storage system – InPhase released its holographic drives, aimed at broadcasters needing to archive TV programs, last year for $18,000 a piece. However, GE’s system could be the first one target end consumers.

Holographic Data Storage Media

Holographic media can store huge amounts of data because information is encoded in layers throughout the entire disk, not just on a single reflective surface as in today’s optical media.

In GE’s system, a single CD-size disk made of plastic will be able to store about 1 terabyte of data, equivalent to 110 typical movie DVDs.

This would make it possible to backup all your data and media in one place, it would also provide the amounts of storage needed for data-intensive applications, such as Microsoft’s MyLifeBits, a project which by archiving emails, texts and snapshots taken from a wearable camera, aims to capture and document everything that happens in a persons life.

The holographic disk stores information by splitting a laser beam (1) in two (2). One of these beams encodes the data by passing though hundreds of gates that are marked open or closed to represent binary 1s and 0s.

The other half of the beam, known as the reference beam, is bounced off a mirror (4), so that the reference beam and the signal beam encoded with digital information intersect somewhere within the plastic storage medium (5). Where the light waves meet, they imprint a three dimensional holographic pattern.

By varying the angle of the mirror, millions of holograms can be created in the same piece of plastic.

To read data from storage, the reference beam alone is used to illuminate the hologram. The resulting image can be read by a sensor and converted back into 1s and 0s.

Manufacturers believe this technology could provide safe data storage without degradation for up to 50 years, far exceeding the current length of time offered by other storage options.
