Blu-ray Media: A New Solution For Digital Media

by : Pablo Zedd

Blu-ray Media is slowly becoming the must have technology for high definition entertainment.

If you are after making your movie collection artwork lasting, then DVD Blu-Ray media disc is the right one for you.

Blu-ray Disc

The DVD Blu-ray disc is an optical disc storage media format, which is developed and promoted by the Blur-ray Disc Association (a group of companies that represent computer hardware, consumer electronics, and motion picture production). The structure of the disc contains a unique reading formulation. It uses blue-violet laser for reading mechanism resulting for a shorter wavelength of 405 nm, roughly shorter than those of a standard DVD or CD (650 nm wavelength). The shorter the wavelength is, the bigger the data storage capacity. Also, the DVD Blu-ray disc both a 25 GB capacity (single layer) and 50 GB capacity (dual layer) and a wide range of usage.

Since the Blu-Ray disc's launched in 2007, its acceptance as DVD media replacement has significantly increased. Blu-ray has had much support from consumers as well as movie studios and this has greatly contributed to its triumph over HD-DVD.g., Warner Brothers, Buena Vista Home Entertainment, Walt Disney). Such positive events led for people to think of it as the next generation media.

Its Unique Recording Layer

Normally, the standard DVD would have a recording layer that is squeezed in between two 0.6 mm layers of polycarbonate plastic. The Blu-Ray Disc on the other hand, has a recording layer of 1.1-mm think plastic substrate and is secluded by a 0.1-mm thin cover layer. Because of this, better disc reading is achieved since the laser does not require traveling distantly to the point of focus. A 0.85 NA lens aperture manages to to hold greater capacity due to larger density which is more focused.85 NA lens aperture.

Any tilt issues that were previously a problem included with substrate stresses can be effectively reduced. Consequently, such stresses occur during the production procedure, specifically while at the injection molding process. Such process may cause the laser light to split in two separate beams (birefringence). If the player overheats, then the system will stop reading any information from the disc.

Having the recording layer closer to the surface however causes some drawbacks. Unfortunately, this leaves the disc exposed to dust, unwanted fingerprint marks, and to some possible accidental abrasions or scratches. Developers created a special layer to cover the disc to effectively avoid any issues associated with scratches. This protective coat is made sufficiently hard to avoid any accidental abrasion or scratch. The great thing is that the special layer can allow you to simply remove the dirt and dust by wiping wiping with a non-abrasive soft cloth. Now this is definitely something you cannot do in a standard or regular DVD or CD media disc.
