IBM's Race Track

It was four years ago that one of IBM's Researcher, Stuart Parkin planned to develop a new type of of memory . According to his calculations this device can offer faster, cheaper and higher storage capacity than RAM or Hard Disk.

Racetrack



In racetrack memory, the bits - 1s and 0s - of data are stored in the tiny magnetic domains of a very thin U-shaped wire. They apply a magnetic field for writing data to the domains. Later, the pulsing current is passed through the wire, which pushes those domains along the track, along sensors that can read off the data.

IBM says this technology could enable handheld devices such as an mp3 player to store around 500,000 songs or around 3,500 movies - 100 times more than is possible today.

Well well what do we have to say about it !!

Holographic disks now a rival for Bluray

Gone are the days of DVD and Bluray here comes Holographic disks with storage upto 300GB..




A Holographic disk is about the size of Dvd which can hold data 60 times more than that of Dvd!!

Can u believe it that there are holographic disks which can hold data upto 300GB..

These disks store information through the interface of light through and a technique known as holographic memory..

Holographic disks were first designed by Inpase Technolgy Inc. located in USA ..

Data can be read and written from these disks @ 10 times faster than normal Dvd's..

The discs, at 13 centimetres across, are a little wider than conventional DVDs, and slightly thicker. Normal DVDs record data by measuring microscopic ridges on the surface of a spinning disc. Two competing successors to the DVD format – Blu-ray and HD-DVD – use the same technique but exploit shorter wavelengths of light to cram more information onto a surface.
.

Holographic recording also improves the data transfer rate which is now 27MB/sec. It was 20MB/sec.
