2. BluE-ray Technologies

3. Main Topics Introduction To Blue Ray Technology
Blue-Ray Technology Contents
Theory of Blue-ray Technology
APPLICATION
Integration of Blue-ray

4. Blu-ray Technology Name
Derived from the blue- violet laser used to read and write data.
Developed by the Blu-ray Disc Association with more than 180 members.
Dell
Sony LG

5. Blue-ray Technology Cont.

6. Data capacity
Because Blue-ray uses a blue laser(405 nanometers) instead of a red laser(650 nanometers) this allows the data tracks on the disc to be very compact.
This allows for more than twice as small pits as on a DVD.

7. Blue-ray Technology Cont.

8. Data Capacity Cont.
Because of the greatly compact data Blu-ray can hold almost 5 times more data than a single layer DVD. Close to 25 GB!
Just like a DVD Blu-ray can also be recorded in Dual-Layer format. This allows the disk to hold up to 50 GB!!
Because the polycarbonate layer of the Blu-ray disc is so much larger than a DVD because the recording layer is so much smaller it can have even more than two layers.

9. Blue-ray Technology Cont.

10. Writing Data
Blue-ray uses a combination of two lenses to greatly shrink the laser to read the data.
This also allows for higher data rate transfer close to 36 mbps.
It could record 25 GB of data in an hour an a half.

11. Blu-ray Technology Cont.
Formats
BD-ROM (read-only) - for pre-recorded content
BD-R (recordable) - for PC data storage
BD-RW (rewritable) - for PC data storage
BD-RE (rewritable) - for HDTV recording

13. Blu-ray Integration

14. Blue-ray discs are able to record HD without any signal loss.
Single layer up to 2 hours of HD video
Dual layer up to 4.5 hours of HD video

15. APPLICATION
DVD Writer
Hard Disk

16. Blu-ray Integration Cont.
Security
Blue-ray discs are better armed than current DVDs. They come equipped with a secure encryption system -- a unique ID that protects against video piracy and copyright infringement.
