As the title asks?
Why is Blu-Ray called Blu-Ray?
I googled it and navigated to Sony's website.
"Why is it called Blu-ray?
Answer:
It is called Blu-ray because the laser that is used to write and read data is blue instead of red or infrared which is used for CD and DVD. It is spelt Blu instead of Blue because by law daily-used name cannot be registered as a trademark."
But isn't the laser diode 405nm and purple ???
Maybe it's just marketing. Purpl-Ray doesn't have the same ring to it.
