Holographic data storage archives data by the use of a pattern of optical interference with a photosensitive, thick optical material. Dramatically increased storage density – Holographic Information Storage breaks the density limits versatule conventional optical storage by recording through the full depth of the medium instead of recording verzatile the surface only.

Tapestry Media — a holographic format patented by InPhase Technologies — having a storage capacity of 1. Additionally, unlike optical discs, which record one data bit at a time, HVDs allow over 10 kilobits of data to be written and read in parallel with a single flash of light – and the recording and reading processes do not require spinning media.

It employs a technique known as collinear holographywhereby a green and red laser beam are collimated in a single beam.

Technological changes have radically changed the way of storing data. Most requested “missing” Pi goes on sale.

The biggest challenge for HVD will be in establishing itself in the commercial market, which as of now seems to be a distant dream, given its higher cost margins.

Ambitious goals – TC44 will begin standardizing three different storage media: HVD uses a technology called ‘collinear holography,’ in which two laser rays, one blue-green and one red, are collimated into a single beam. Such large optical storage capacities compete favorably with the Blu-ray Disc format.

Traditionally, holographic storage systems contained no servo data, because the beam carrying it could interfere with the holography process. Mail this article Print this article. This would, without a doubt, become a giant step in revolutionizing the disk storage industry.

The role of the blue-green laser is to read the data encoded in the form of laser interference fringes from the holographic layer on the top, while the red laser serves the purpose of a reference beam and also to read hbd servo info from the aluminum layer — like in normal CDs — near the bottom of the disk.
