Answer:
The name "Blu-ray" refers to the blue laser (which is actually a violet laser) used to read the disc, which allows information to be stored at a greater density than is possible with the longer-wavelength red laser used for DVDs.
Explanation:
BD-R, BD-RE and BD DL
When Blu-ray first came out, there were really only two types of discs: write and rewriteable. BD-R discs are write-only and BD-RE are rewriteable. The standard size for these discs are 25 GB and they only have one layer.
