You can probably can remember the days when folks watched their property movies through their VCR's. Of course these VHS tapes were bulky, consumer plenty of storage room, and output reduced quality visuals than seen today with DVD's and also the emerging BD media. LaserDiscs's soon thereafter replaced the VHS and VCD's however this was short-lived when DVD was brought to the scene. DVD (Digital Versatile Disc) was of course far more advanced than VCD and stored six times more info.

A single DVD using a storage capacity of 4.7 GB is capable of doing storing one full-length movie and also other behind-the-scene footages and also other extras. Because of this, DVD's also have a significant influence on the movie industry and consequently a lot more people are purchasing DVD's to see within their homes. The DVD may however get replaced by the new technology that might further enhance the movie industry. The new Hi-def media technology is called Blu-ray.

Of course BD's are consider by many people is the next gen format to take off when DVD's begin to drop. Blu-Ray Discs or BD can record, store and can play-back more video, digital audio, in addition to computer data. BDs may also store a full length high-definition movie which usually requires a higher bandwidth and space for storage. When compared with DVDs. Blu-Ray Discs hold the edge over the quantity of information that it may store. A single-layer BD has the capacity to store 27 GB of digital information. A blu-ray disc has this type of large capacity when compared with DVD in this her power to hold up to 13 hours more of standard video. A double-layer BD on the other hand might be in a position to store over 4.5 hours of high-definition video because of its 50 GB storage capacity.

Laser lights are effectively the best way optical disc storage media (for instance DVD and Blu-ray) can read information, with Blu-ray utilizing blue violet rays whereas DVD uses red ultraviolet rays. The amount of information which can be saved in discs relies upon how large and precise the laser light is. Blue laser carries a shorter wavelength compared to red laser and because of this, blue laser is a bit more precise and may write information in more compact spaces. This is the reason why far more information can be kept in a Blu-Ray disc.

A tremendous storage capacity is not only advantage of a Blu-Ray technology. Blu-Ray Discs may also transfer information with a higher rate. Blu-ray discs are really revolutionary since they're able to a data transfer rate of 36 Mbps (megabits per second) whereas an ordinary DVD are only able to transfer at a rate of 10 Mbps.
