I've just bought a BluRay, and I want to know how it works. I'm not searching for a high-level scientific explanation--just a simple answer.

Questions on Physics Stack Exchange are expected to relate to physics within the scope defined by the community. Consider editing the question or leaving comments for improvement if you believe the question can be reworded to fit within the scope. Read more about reopening questions here.If this question can be reworded to fit the rules in the help center, please edit the question.

I don't think the question as it is written here belongs here. We don't know from your question whether the answer you want is about the electronics, the file-format, the wavelength of the laser, etc... If you look at wikipedia or the first result of a google search, you can already have some answers. If they're not good enough from you, edit your question and explain why they are not satisfying. – Frédéric Grosshans Apr 2 '12 at 16:21
Technology question, not a physics one. – dmckee Apr 2 '12 at 19:43

Please note that answers that are just links are discouraged--you must give atleast an overview of the phenomenon explained in the link--otherwise your answer is liable to being downvoted. – Manishearth Apr 2 '12 at 15:03
@Manisheart just a quick one, do you like run this site or something? – ODP Apr 2 '12 at 22:00
@Olly: Nope ;). This site is run by virtually nobody--or you could say that the community runs it. I'm just a normal user, who downvote+comment's on bad posts. Others do this as well. Moderators (they have a ♦), and 10k+ rep users do a bit of the behind-the-scenes work. SO staff members (also ♦) could be said to run the site; but they also do so after listening to community input. – Manishearth Apr 3 '12 at 2:50
