Blu-ray Burner

With the format war between Blu-ray and HD-DVD already a distant memory, the future is looking pretty good for Blu-ray. New players and recorders are being released every month and their falling prices are attracting new buyers. Many people who have made the switch to high definition television are now looking to upgrade their computers with a Blu-ray burner. They have realized that there is little point in owning a high definition camcorder if the video footage needs to be compressed to fit onto a DVD. Blu-ray discs have a much greater capacity, which allows hours of high definition video to be stored on a single disc.

Blu-ray is an optical disc format that is typically used to store high definition media. The name may sound a bit unusual but it simply refers to the blue laser beam used to read data from a disc. Data is stored in the same way as it is stored a CD or DVD, just with a much greater density. Blu-ray was designed to replace the incredibly popular DVD format, which does not enough storage capacity to hold an entire movie recorded in high definition. The discs have the same dimensions as a CD or DVD, but the case is slightly different to a standard DVD case.

The process of writing data with an optical disc recorder is called burning. A tiny laser inside the recorder creates millions of microscopic holes in a special dye layer on the disc. Burner is a slang term for a recorder that is designed to be installed in a computer, and is rarely used to describe a standalone recorder that is plugged into a television. A Blu-ray burner is a device that can read Blu-ray discs and write data onto special blank discs. Despite being almost identical to a CD/DVD burner, it currently costs more to buy one because it is a new technology that everyone wants.

The most important feature to look for when choosing a Blu-ray burner is fast writing speeds for all types of recordable disc. The high storage capacity of Blu-ray discs means that even a small deficit in speed can result in a huge increase in recording time. Also, the writing speed for rewriteable Blu-ray discs (BD-RE) is typically much slower than that for regular blank discs (BD-R). A Blu-ray burner should also have fast reading speeds, but these are typically much higher than the writing speeds and are only noticeable when large files are being copied.

A Blu-ray burner can read and write any type of CD or DVD, including the rewriteable types. However, only a Blu-ray burner can write media onto a Blu-ray disc. Blank discs are currently available in two capacities. The single-layer disc can hold up to 25GB of data, which is about six times the capacity of a DVD, and the dual-layer disc can hold twice as much. Blank discs are currently very expensive, just as blank DVDs were when they first introduced. In the future, the discs will be more affordable and have more layers, which will allow much more data to be stored on them.

As more people upgrade to high definition televisions and computer monitors, Blu-ray will become the standard for storing media on optical discs. However, the CD and DVD are not going to disappear any time soon but will eventually fade away over time, just like the vinyl record and VHS tape before them. The CD/DVD burner that is a standard feature of computers today will be replaced by the Blu-ray burner. However, even Blu-ray will most likely have a short lifetime as the trend towards using online storage and wireless connectivity gathers pace. One thing is certain, all media in the future will be high definition, regardless of how that media is stored.
