Blu-ray discs use blue lasers, which have a smaller wavelength than other lasers. Another important factor determining optical disc performance is the wavelength of the laser light. To make the disc's surface big enough to accommodate a large quantity of data, the pit size must be small. The data capacity of Blu-ray discs depends on the size of the pits on the disc's surface. Another advantage is that blu-ray discs are forward compatible with new devices, so you'll never need to worry about your data getting lost. Plus, they're cheap compared to other storage media. In addition, they can be easily transported from one device to another. Because they are write-once, they are immune to computer viruses, power failures, magnetic interruptions, and water damages. High-definition television is everywhere, and new disc materials will make it possible to store ridiculous amounts of data.īlu-ray discs are incredibly durable and have many advantages over standard hard disks.

They can hold much more data than standard DVDs, allowing higher-resolution movie files to be stored on a single disc. It can store large amounts of dataīlu-ray discs have the potential to store a lot of information.

The format also supports high-definition audio at up to 7.1 channels. Its high-definition (HD) video offers six times the picture resolution of a DVD and supports higher bit rates. This is enough to play more than four hours of HDTV.īlu-ray is the next-generation optical disc format. A typical DVD can hold only 4.7 GB of data, while a single-sided Blu-ray disc can store up to 25 GB of data.

However, Blu-ray's grooves are much thinner than DVD's, making it possible to store more data on a single disc.Ī Blu-ray disc can store an astonishing amount of data, and is therefore ideal for recording and playing high-definition movies and TV shows. A laser in the drive follows the grooves and interprets the encoded information. The technology behind Blu-ray is based on similar engineering concepts as DVD, with the difference that Blu-ray uses a single, 1.2-millimeter polycarbonate disc with spiral grooves for storing digitally encoded video and audio data. Some of these include the Chinese made EVD and the red-laser Versatile Multilayer Disc (VMLD). Several companies have attempted to create alternative high definition optical disc formats. For example, the manufacturing facilities for HD DVDs need to be upgraded or replaced before they can be converted to Blu-ray discs.

The main differences between these formats are their surface layer thickness and the production facilities required to create them. HD DVDs and Blu-ray are two high definition optical disc formats, but they are not interchangeable. Blu-ray is a high definition optical disc format
