Blu-ray, known as Blu-ray disc (BD), is a next generation format developed to deliver High Definition video content and or large amounts of data. As a digital optical disc data storage format, it was first created by a group called the Blu-ray Disc Association which represents makers of consumer electronics, computer hardware, motion pictures and media manufacturers. It is capable of storing, recording, rewriting and playback several hours of video in high-definition (HDTV 720P and 1080P), ultra high-definition resolution (2160p), as well as large amounts of data. How much data can a Blu-ray disc hold? As its format is able to provide more than five times the storage capacity of traditional DVDs, it can hold up to 25GB on a single-layer disc and 50GB on a dual-layer disc.
What is more, Blu-ray products can easily be made backwards compatible with CDs and DVDs. Currently, Blu-ray is supported by about 200 of the world’s leading consumer electronics, personal computer, recording media, video game and music companies. And a lot of studios have also announced that they will begin releasing new feature films on Blu-ray Disc day-and-date with DVD, as well as a continuous slate of catalog titles every month. How does Blu-ray work? Below is the answer.
How does a Blu ray work?
How does Blu-ray work? As we all know, digital information is stored on optical devices in pits along a spiral groove running along from the center of the disc to its edge. The blue laser allows BD to utilize smaller pits and lands than are used on SD DVDs. To figure out how how much data can a Blu-ray disc hold, keep reading further more. Because the pits and lands are smaller they can be placed closer together resulting in more information being stored on the same size disc. The higher number of pits translates to a higher capacity for the disc. These smaller areas of data can then be read by a shorter wavelength blue laser. DVDs, for example, use 650-nanometer red lasers during operation, however by decreasing the wavelength of the laser beam to 405 nanometers – blue light, which also gives the disc format its name – smaller pits may be written/read on the support surface. That is how Blu ray works. With the combination of different optics and faster disc rotation, BD discs can store 5X more data than SD DVDs.
Though the Blu-ray and DVD discs have the same thickness, the Blu-ray discs also solve the problems which are related to birefringence and disc tilt. In general, when the laser beam becomes so distorted and reading processes cannot be carried out, by making use of a much thicker polycarbonate layer, while laser system stands closer to the disc surface thus removing the disc-tilt reading problem. With the detailed explanation, we understand more about how Blu-ray works.
What are Blu-ray Region Codes?
In fact, it does take some time to digest how Blu-ray works. As Blu-ray is popular, have you ever encountered the case that you bought some dis abroad, but found it impossible to play on your Blu-ray players? In some case, it is owning to Blu-ray Region Codes. But what are Blu-ray Region Codes? Blu-ray discs contain Regional Codes which are used to prevent the playback of region coded discs outside the area they are made for. In other words, Blu-ray Disc players purchased in countries corresponding to region A can play back Blu-ray Discs for region A, but cannot play back Blu-ray Discs for region B or region C. Last but not least, the region code settings for a Blu-ray Disc player device cannot be changed. The Blu-ray Region Codes are broken down as follows:
- Region A: North America, South America, U.S. Territories, Japan, South Korea, Taiwan, and other areas of Southeast Asia
- Region B: Europe, Africa, Middle East, Australia, and New Zealand.
- Region C: Asia (except for Japan, Korea, Taiwan, and other areas of Southeast Asia)
