What is a blue ray disc? What makes it different from a DVD?

Answer 1

The disc may look the same, but its not:

As the name suggests, BlueRay uses a BLUE laser to read the data off of the disc, a regular DVD uses a RED laser. Blue lasers are more focused, so the data can be read from a smaller area. That enables more data to be stored on one disc. Which means HD picture qulaity, HD sound, loads more interactive disc option Blah Blah. Get the idea?

Answer 2

a blue ray disc is pretty much the new way to watch movies since their high definition better sound, and holds way more space than a dvd, the average dvd holds up to 4GB and a blu-ray disc holds up to an average of 25GB and it has better picture on a plasma tv

Answer 3

Blue ray is a technology invented by sony it is similiar to a HDDVD ( high def dvd) only it is in a different format and can hold more data. Meaning better quality movies.

Answer 4

This is also the new HD DVD, if your old enough you may remember the days of VHS and Beta Tapes, they were two competing formats. In the end VHS won out.

Now we will have two types of HD, give it a while and we'll be back to one.

Answer 5

its in high-def and it is packed with a TON of extras that you could NEVER pack onto a regular DVD with extra stuff in each disc like director commentary break down of a scene and outtakes, more stuff packed onto a single cd in high-def

Answer 6

Larger capacity so that you can hold more info on it...or in the movies..make the picture clearer and at its PEAK performance..but you will pay for it..

Answer 7

I`m pretty sure it only work with a playstation3
