Blu-ray, also known as Blu-ray Disc (BD), is the name of the next-generation optical disc format jointly developed by the Blu-ray Disc Association (BDA), a group of the world's leading consumer electronics, personal computer and media manufacturers including Apple, DELL, HP, Sony, Samsung, LG, Pioneer,TDK & a few others.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. This extra capacity combined with the use of advanced video and audio codecs will offer users an unprecedented HD (High-Definition) experience.As the name itself suggests, BD makes use of a 405nm blue-violet laser rays to read & write data on the disc.The benefit of using a blue-violet laser is that it has a shorter wavelength than a red laser (650nm) used for DVD, which makes it possible to focus the laser spot with even greater precision. This allows data to be packed more tightly and stored in less space, so it's possible to fit more data on the disc even though it's the same size as a CD/DVD.
The Blu-ray has left no choice for movie & game lovers like me, but to go for a BD player, since most of the major movie studios including Fox, Warner, Paramount, Sony, Lionsgate etc. have already decided to release their movies exclusively in the Blu-ray format. PS3 Games are already in the market on BD and it won't be too long before XBox360 also joins the club.
Since BD players support DVD/CD playback also, one single player would do the job, but what I'm really worried about is the price of a BD writer once it arrives in SL market. GOD please don't make it sky high......................
