Enter the Blu-Ray

Today I saw an ad. for the release of Night at the Museum on DVD, at the end the guy says "available on DVD and Blue Ray" thats when I jumped and said " WHHHHHHHHHHHHAt????!" yup thats what I did. What the heck is a blue ray, at first I thought its something old like VHS something too old that I probably forgot. I couldn't help not knowing what the fuck is a blu-ray and since I'm not a sony fan, I did not know what it was. I started browsing the net to find da blue ray and I found it, well of course I did it seems like every Play Station fan around the world is talking about it.

Blu-ray is a high-density optical disc format for the storage of digital media, including high-definition video. It stores up to 25 GB (single layer) and 50 GB (double layer) and plays up to 9 hours of HD video and about 25 hours of SD videos. the disc is pretty much the same as a regular CD or DVD in shape it also comes in either a 12 cm (25 GB) or 8 cm (7.5 GB) "single sided".

The Blu-ray Disc system uses a blue-violet laser operating at a wavelength of 405 nm, similar to the one used for HD DVD, to read and write data. Conventional DVDs and CDs use red and infrared lasers at 650 nm and 780 nm respectively.

I could just go on and on with this since there is so much to say, so for more information go to some technical web site like techspot. And now I guess I know why the PS3 is very high priced compared to other consoles, but this does not mean that I'm gonna buy a PS3 actually I find it quite dumb from sony to release only one type of its console and claims a high price just because it has a blu-ray reader that might not be used till the next couple of years.
