How Do BD-R Drives Work?
To comprehend how BD-R drives operate, we need to start with the components involved in the process, including the discs themselves and the technology that enables writing and reading.
The Technology Behind BD-R
-
Composition: BD-R discs utilize a blue-violet laser (405 nm wavelength) to write data. This is different from traditional CDs (which use a red laser at 650 nm) and DVDs (which use a slightly longer wavelength). The blue-violet laser’s shorter wavelength allows for tighter data packing, which leads to increased storage capacity.
