Physical Principles of DVD Technology

[Jaar-Gilon]

I have an assignment due tomorrow (year11) about DVD Technology and physics involved. I can't seem to find any info on the Physics behind DVD Technology or anything related to the topic, if anyone has a handy website or any info on Dvd Technology and related physics that would be awesome, cheers.
