    ABSTRACT Optical disks share a major part among the secondary

    storage devices. Bluray Disc is a nextgenerationoptical disc format. The technology utilizes a blue laserdiode operating at a wavelength of 405 nm to read andwrite data. Because it uses a blue laser it can store

    enormous more amounts of data on it than was everpossible.

    Data is stored on BluRay and can record up to 2.5hours of very high quality audio and video on a singleBD.

    Bluray also promises some added security, makingways for copyright protections. Bluray discs can have

    a unique ID written on them to have copyrightprotection inside the recorded streams.

    Bluray disc takes the DVD technology one step

    further just by using a laser with a nice color

    INTRODUCTION

    Blu ray - Optical disc storage to

    supersede the DVD format.

    Optical disc - electronic data storagemedium that can be written to and read

    using a low-powered laser beam.

    Why blu ray? blue laser to read the

    LITERATURE REVIEW

    History:Year(s) What happen?

    1958 The optical disc was invented by David Paul Gregg

    1961 David Paul Gregg registered a patent for the analog

    optical disc for video recording as video disc1968 Music Corporation of America (MCA) was purchased that

    patent and continue to further development

    1969 Philips Research Physicists began their first optical video

    disc experiment at Eindhoven

    1975-1978 Philips and MCA were work together to do this

    development but fail

    1983 Philips and Sony were together to develop the audio

    compact disc successfully

    Mid-1990s The second generation of optical disc, Digital Video

    Disc/Digital Versatile Disc (DVD) was developed

    Year(s) What happen?

    1998 Commercial High Definition Television (HDTV) sets had

    begun to appear in the market

    2000 Shuji Nakamura, a professor in the College of Engineering

    at University of California introduced Blu-ray prototypes at

    Combined Exhibition of Advanced Technology (CEATEC)

    Exhibition2002 Blu-ray Disc Founders was founded

    2004 Blu-ray Disc Founders change to Blu-ray Disc Association

    (BDA)

    2006 BD-ROM specification were finalized and the first Blu-ray

    players hit the marketJanuary 2007 Hitachi showcased a 100GB Blu-ray Disc (4 layers, 25GB

    each)

    End of 2008 Pioneer Corporation unveiled a 400GB Blu-ray disc (16

    data layers, 25GB each)

    Year(s) What happen?

    2009 Panasonic unveiled the first portable Blu-ray disc player,

    DMP-B15.

    Sharp introduced the first LCD HDTVs with integrated

    Blu-ray disc player, LC-BD60U and LC-BD80U.

    Dec 2009 The Blu-ray Disc Association (BDA) officially announced3D specs for Blu-ray Disc.

    Jan 2010 Sony and Panasonic are corporated to increase the

    storage capacity on their Blu-ray discs from 25GB to

    33.4GB via a technology called i-MLSE (Maximum

    Likelihood Sequence Estimation)

    July 2010 The research team of Sony and Japanese Tohoku

    University are corporated to create Blu-ray discs with a

    capacity of1TB (dual layer)

    Features of Blu-ray Disc:-1. Content Protection

    o provides some of the strongest copy protectionmethods (protect from piracy). Its incorporates arobust copy protection mechanism.

    2. Lifespano can stay relevant for at least 10 years to 15 years. Its

    high storage capacity of 25 to 50 GB (best suitable forHigh Definition video quality and most data storagedemand).

    3. Broadest Industry Supporto previous history have shown that the development of

    Blu-ray disc was supported by many electronicsmanufacturers and IT companies like Dell, HP,Hitachi, LG Electronics, Matsushita (Panasonic),Mitsubishi, Pioneer, Philips, Samsung, Sharp, Sonyand Thomson/RCA. Its make faster development of

    Blu-ray disc.

    4. Production cost (cheaper)o 10% of DVD production costs, although a Blu-ray

    Disc offers 5-10 times the capacity. Blu-ray Discrequires fewer slots in a replication linecompared to other formats. Blu-ray Discs do notrequire cartridges.

    5. Capacityo Provide large capacity with more data storage

    (25 GB).

    6. Robustness of Disc6

    . Blu-ray disc is much stronger resistance toscratches and fingerprints than other existing andproposed formats. Its do not require a cartridgeand can be used as a bare disc. Then, avoidsextra production costs.
