We have been hearing a lot about new and old Bollywood and Hollywood movie titles being released and re-released on Blu-ray. But, have you ever wondered what that Blu-ray disc actually is, when you saw it sitting right next to the good old DVD, in that electronics store? Well, to be brutally honest, you aren’t the only one wondering about the same question. Party because on the outside, the Blu-ray disc looks exactly like a standard DVD. And mostly because the price of the Blu-ray is at times more than twice of that of a DVD title. A lot of people have been asking what Blu-ray is and how it is different from the DVDs we have been using for quite a while now.
Blu-ray: The simple definition
Blu-ray is, essentially, a new optical disc format, which supports storing huge amounts of data into one optical disc. A single layer Blu-ray disc holds about 25GB of data and a dual layer Blu-ray disc holds about 50GB of data. These discs can not only hold more data than a standard CD or DVD (even the dual layer ones), but are also extremely useful for High Definition movies. This format has been developed in association by a combination of big names in the technology sector- Sony, Panasonic, Mitsubishi, Philips, Samsung, HP, Dell, Apple, Sharp, Pioneer, LG, TDK and Thomson. These brands have come together under the umbrella of Blu-ray Disc Association (BDA).
