Technology and why mi should care bout it [img]/forums/images/%%GRAEMLIN_URL%%/confused.gif[/img]
Mi deh innna di Black Friday Habaloo ahn mi notice daht certain DVD Player ahn DVD seh dem is BlueRay. Wah daht fah?

Re: What exactly is BlueRay

think of saving like 50GB on a disk.

I was thinking I should have put some money into this when I first heard of it but I never did. [img]/forums/images/%%GRAEMLIN_URL%%/70361-embarassed.gif[/img]

Re: What exactly is BlueRay

Holographic-memory discs launched next year

Better than a DVD
By Nick Farrell: Friday 25 November 2005, 07:49

A FIRM which makes a disc that can hold 60 times more data than a DVD said it is ready to release the product next year.
InPhase Technologies, based in Colorado, has developed a commercially viable version of a holographic disc which can hold 300 gigabytes of data and can be used to read and write data 10 times faster than a normal DVD.
InPhase Technologies spokesperson Liz Murphy said that unlike other technologies that record one data bit at a time, holography allows a million bits of data to be written and read in parallel with a single flash of light. This enables transfer rates significantly higher than current optical storage device.
The discs, are 13 centimetres across and a little wider than normal DVDs. They store data in a light-sensitive crystal material using the interference of laser light. A single light beam is split and passed through a semi-transparent material. This acts like a filter, changing different parts of the beam to encode bits of information.
The altered beam and the reference beam are then recombined in the light-sensitive material and their pattern of interference provides a record of the encoded information.

Re: What exactly is BlueRay

A computer disc about the size of a DVD that can hold 60 times more data is set to go on sale in 2006. The disc stores information through the interference of light – a technique known as holographic memory.
The discs, developed by InPhase Technologies, based in Colorado, US, hold 300 gigabytes of data and can be used to read and write data 10 times faster than a normal DVD. The company, along with Japanese partner Hitachi Maxell announced earlier in November that they would start selling the discs and compatible drives from the end of 2006.
"Unlike other technologies, that record one data bit at a time, holography allows a million bits of data to be written and read in parallel with a single flash of light," says Liz Murphy, of InPhase Technologies. "This enables transfer rates significantly higher than current optical storage devices."
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.
Beam-splitter
Holographic memory, by contrast, stores information in a light-sensitive crystal material using the interference of laser light. The process involves splitting a single light beam into two and then passing one through a semi-transparent material. This is a grid that acts like a filter, changing different parts of the beam to encode bits of information.
The altered beam and the reference beam are then recombined in the light-sensitive material and their pattern of interference provides a record of the encoded information. Information can be recorded and retrieved so rapidly because many bits of data can be recorded and read in parallel.
InPhase says the technique could theoretically be used to store up to 1.6 terabytes of data on the same size of disc and to read data at 120 megabits per second. This is 340 times the capacity of an ordinary DVD and 20 times the data rate.
High-speed streaming
Although holographic memory was first suggested in 1963, it has failed to find commercial success so far. However, Hans Coufal, an expert in the technology at IBM's Almaden Laboratory in California, says the holographic memory could challenge formats such as Blu-ray and HD-DVD.
As well as offering greater storage, Coufal says the main benefit is speed of data access. The discs developed so far by InPhase can already stream a movie recorded in high definition television (HDTV) format.
However, Coufal notes that the technology must also stand up to everyday use. "It is an open race right now," he told New Scientist. "But you have to convince the customer that it is going to be reliable."

Re: What exactly is BlueRay

so wah is dis chat mi hear one salesman inna di store wid? im seh soon all of wi will know if BlueRay is di standard, as BlueRay is in competition wid sinting else (mi figget which one im seh). im juss hope BlueRay nuh end up like BETA. Wah im chatting bout [img]/forums/images/%%GRAEMLIN_URL%%/confused.gif[/img]

yuh membah de likkle war between beta an vhs?
next ting yuh nuh everybody who bought beta was outta luck cah dem stop mek de tape dem, de machine dem everyting. Some ppl swear beta was bettah den vhs. Him nuh waan si bul-ray guh de same way.

Re: What exactly is BlueRay

oh yes, mi vaguely rememba BETA tapes.
mi will continue watch dis BlueRay ting den. plus it high right now...di price soon come dung.
