Holographic data storage technology pdf

Overtime, the general value of holographic information storage ought to decrease to a suitable quantity. Considering all positive and negative aspects, it's currently nearly bound that the. Holographic storage technologies are going to be the winner among the competitive ones. This may be the gap of a brand new space in information storage and processing.

Applications requiring and victimization remarkably high storage capacities can revolutionize content distribution, mobile computing and international info security. Prospects embody a lot of economical querying radical dense databases, new varieties of displays, and ultrafast processors engraved into holographic material. However, the technology still desires a number of a lot of years to supply common-place reasonable merchandise.

PDF Version View. It highlights the importance and wish of this technology. The demand for will increase within the capability and speed of information storage tests the bounds of typical technologies and drives the hunt for new approaches. The growing demands of high definition digital video content, fastened content knowledge, and compliance and security application can shortly outstrip the capabilities of current storage technologies to stay up the demand.

Clearly a replacement storage paradigm is required to fulfill the growing storage demands. The decreasing price of storing knowledge and therefore the increasing storage capability of identical tiny device footprint are key enablers of this revolution.

This image is absolutely simply targeted lightweight. Holographic knowledge storage records info throughout the quantity of the medium and is capable of recording multiple pictures within the same space utilizing lightweight at completely different angles. Considering all positive and negative aspects, it's currently nearly bound that the Holographic storage technologies are going to be the winner among the competitive ones.

Since these all are 2D holographic storage products save 1 million pixels at a time storage devices, they are cheap and stable. The overall in discrete image, and these images are also called pages, storage capacity was increased with each new generation of which form tiny cones through the thickness of the light- devices.

Holographic data storage is a new technology in the sensitive media. Present holographic media can store over field of high-capacity data storage currently conquered 4. Writing mechanism of Holographic data storage WORM technology that depends on light-sensitive media Two Lasers beams Write the Hologram wrapped in removable protective cartridges.

In holographic data storage, the whole page of information is Based on the binary pattern of data, the shutters are opened stored at one time as an optical intervention pattern within a and closed accordingly. If we use a matrix of by thick, photosensitive optical material. This is the reasons bits, it can store bits.

As per theory concepts it can write millions of pages in the same optical area and as per data the first holographic optical of conventional storage by going above the technique drive has recorded holograms. The grouping of high storage mediums, fast data transfer rates, and strong, consistent and low cost media, make holography balanced to become a convincing option for next- generation data storage solution of the commercial organization, medical field , government sectors and telecom industries.

In this type of technology, holographic storage uses two laser beams, one is reference beam and other is data beam to create a compatible pattern at a medium where the two beams interconnect. This intersection causes a stable physical or chemical change which is stored in the medium. This is the Fig Writing data into disc[6] B. Reading mechanism of Holographic data storage One single Laser beam Reads the Hologram To read the page the reference laser beam is directed back into the hologram and the light is diffracted into the binary Figworking of holographic disk[7] data and this data is sensed by the sensors.

While reading data, the action of the reference beam and the interference pattern stored in the medium regenerate the data beam which may be sensed by a detector array. The medium may be anything such as a rotating disk which contains a polymeric material, or an optically sensitive with crystal material.

The thick layer is about 1 mm in thickness and is made up of holographic material. Number of holograms can be stored at every location of surface of disk. These locations are organized with circular tracks, in which the head motion selects a track, and the disk accesses each track with each rotation.

Number of holograms can be stored by increasing the thickness of the layer which results in the higher surface density. Practically it is desirable to manufacture disk of 1 mm which consists of density of bps. The important factor is the configuration of surface density as compared to volume density because it stores the data in 3D. To multiplex holograms on the disk the Angle multiplexing technology is used. Because of angle scanner, the read head becomes very large in size and also becomes heavy for fast access to holograms on various disk.
