DVDs and Blu-ray discs, so easy to use, a caveman can use them!

By: ~Hotter then da sun~


        Have you ever heard of Blu-Ray discs?  If you have, you probably heard of them from a commercial for a movie.  They say something like: the best movie ever!  Coming to DVD and Blu-ray June 1st.  Have you ever wondered what Blu-ray is?  Well if you read my report, then you will know all about DVDs and Blu-ray.  I hope you enjoy it!

What in the world are DVDs and Blu-Ray discs?

         Have you ever wondered what DVD stands for?  DVD stands for digital videodisc.  That means that you can put a movie or a audio track onto it and with the right hardware, you can play that movie or that audio track.  Pretty cool, huh.

       So, what is up with the spelling of Blu-ray Blu-ray.com says that the spelling of Blu-ray is not a mistake; the letter "e" was left out so the term could be registered as a trademark.  Apparently, a commonly used word can't be trademarked.  I really never knew why it was spelled that way until I looked at that website.  Blu-ray looks really cool though, sort of like a mix between Blue and ray. 

       Talking about the name Blu-ray, do you know how it got the name Blu-ray?    Well, according to wikipedia.com, the name Blu-ray Disc came from the blue-violet laser used to read and write this type of disc.  This laser is the reason that Blu-ray discs are high definition.  Technically, Blu-ray discs are like DVDŐs except for they are much nicer.  

       Well, now that you know a little bit about what Blu-ray is, why donŐt we talk about who uses Blu-ray discs.  According to WashingtonPost.com, Play station 3 uses a type of Blu-ray disc.  So if you have a play station 3, you might have a ton of Blu-ray discs that you donŐt even know about!      

       This paragraph is about the difference between the lasers DVDs and Blu-ray discs use.  According to wikipedia.com, Blu-ray Discs use a blue (technically violet) laser operating at a wavelength of 405 nm to read and write data.  Conventional DVDs and CDs use red, (near infrared) lasers at 650nm and 780 nm respectively.  So apparently, violet lasers are more high definition than infrared lasers.  I think thatŐs a really cool fact.

History of the DVD and Blu-ray disc

       This paragraph is about who won the war between HD-DVD and Blu-ray.  According to John P. Falcone and Matthew Moskovciak, HD-DVD is closing and they will not be making any more HD-DVD products.  So that means that Blu-ray won the fight!  I am very happy for Blu-ray because DVD already sells a ton without HD-DVD.  So they should be totally fine.



        I hope you learned a little bit about DVD and Blu-ray.  Thanks for reading! J
