Understanding Blu-ray Technology
Overview
With the advancement in technology, recording and storing high-definition (HD) content on DVDs has become possible. Blu-ray Disc is a prominent method for achieving this using optical discs.
What is Blu-ray?
Blu-ray technology utilizes a blue-laser optical disc (either MPEG-2 or MPEG-4) to store HD content. It can also play traditional DVDs but aims to deliver an image quality as close to HD as possible. The name "Blu-ray" originates from the blue laser used to read and write data on the disc.
Key Features
The Blu-ray format offers significantly higher storage potential compared to standard DVDs. A single-layer Blu-ray disc holds approximately 25 gigabytes, accommodating about four hours of HD content. Double-layer discs can store up to eight hours. Innovations are underway to create four- and eight-layer discs with capacities of 100 and 200 gigabytes, respectively. Blu-ray achieves this by using a shorter wavelength for recording, allowing more data on a single disc.
Impact on the Computer Industry
Blu-ray has influenced data storage in the computer world. Major companies like Apple, Dell, Hitachi, Pioneer, and Sony are endorsing this technology. Hewlett Packard plans to incorporate Blu-ray into their range of desktops and laptops. Sony's PlayStation 3 will also feature Blu-ray, while Microsoft is considering adding it to the Xbox 360. Initially available only in Japan, Blu-ray is set to launch in the U.S., enhancing video games and providing a high-definition effect on TV systems.
Support from Movie Studios
Many studios are planning future Blu-ray releases. In 2005, Sony Pictures released the first feature-length movie on Blu-ray, "Charlie's Angels: Full Throttle." Other supporters include Walt Disney and Twentieth Century Fox.
The Competition
Blu-ray faces competition from HD DVD, which offers less storage but is cheaper to produce. Supporters of HD DVD include Microsoft, Intel, Toshiba, and Universal Studios. Some companies, like Samsung, Paramount, and Warner Brothers, are hedging their bets by supporting both Blu-ray and HD DVD technologies.
Other Competitors
Apart from HD DVD, Blu-ray contends with alternatives like the Enhanced Versatile Disc, Digital Multilayer Disc, and Holographic Versatile Disc. Despite this, Blu-ray currently leads the HD market.
