Find Recordable Blu-ray

The term "Blu-ray disc recordable" will soon be entering the consciousness of technophiles worldwide as this new media format becomes increasingly affordable and viable for the individual consumer. It refers to a pair of media formats that can be created using specialized Blu-ray optical disc recording equipment. The acronyms used to describe these formats are BD-R and BD-RE.

The Difference Between the Two Major Blu-ray Disc Recordable Formats

Just as with CD-Rs, the BD-R format refers to a Blu-ray disc that is recordable only once, but readable many times over. Similarly, the BD-RE designation refers to formats that are rerecordable, allowing users to create and use, then erase and reuse discs again and again.

The advantage of this format is that is allows users to record much more data than a conventional DVD can hold, even though it's the exact same size. The difference is in the color of the laser light used during the writing and reading process. Data density capabilities are determined by the wavelength of the light used in writing and reading. The shorter the wavelength of the light, the greater the data density the format can achieve. The BD-R and BD-RE formats are created using short-wavelength blue-violet light, while conventional CD and DVD burners use higher-wavelength red laser light instead.
