This document presents a seminar on Blu-ray disc technology. It introduces Blu-ray discs as next-generation optical discs that can store high-definition video and large amounts of data using a blue-violet laser. The presentation covers the motivation for Blu-ray technology, including its ability to support 1080p video and uncompressed surround sound. It also describes Blu-ray's circuit diagram and advantages like recording without quality loss, as well as disadvantages like high costs. The future aspects section discusses how Blu-ray discs will change the video industry and replace DVDs as the standard format.

3. INTRODUCTION
• Blu-ray, also known as Blu-ray Disc (BD) is the name of a
next-generation optical disc format. The format was
developed to enable recording, rewriting and playback of
high-definition video (HD), as well as storing large
amounts of data.
• The format offers more than five times the storage capacity
of traditional DVDs and can hold up to 25GB on a single-
layer disc and 50GB on a dual-layer disc.

5. MOTIVATION
• High capacity storage of video and data
• 1080p high definition video support
• Uncompressed surround sound.
• Increased data transfer rate.
• Better scratch resistance .

6. TECHNOLOGY DESCRIPTION
• Blu-ray systems use a blue-violet laser operating at a
wavelength of 405 nm.
• Hard-coating Technology
•Pits
•Bumps
•Track pitch

7. CIRCUIT DIAGRAM

8. ADVANTAGE
• Record high-definition television (HDTV) without any
quality loss.
• Instantly skip to any spot on the disc.
• Record one program while watching another on the disc.
• Automatically search for an empty space on the disc .

9. DISADVANTAGE
• Very expensive technology
• You will need a 1080P TV to really see the difference
• Not widely used by the general public

10. FUTURE ASPECTS
•Blu-ray discs will definitely change the future of the video
industry
•The Blu-ray discs have won the battle against HD DVDs
and will continue to grow
•Eventually Replace the DVDs as the standard disc format

11. REAL TIME APPLICATION
