Have you wondered why our system asks to burn the data into CD or DVD?
Why does the system use the word burn instead of copy? Doesn't it sound like it is asking to put the data into fire?!
Here is the reality behind the word burn.
The information on a disc is recorded in the digital form, representing a series of zeros and ones. A disc has a thin reflective metal sheet with a translucent dye layer on the top. The CD writer is equipped with a powerful 'write laser' that burns translucent dye to make it opaque. The parts which are opaque block light from the reflecting of the metal sheet, giving them a digital value Zero. The parts which are left translucent get a value of One.
This is why the word burn is used instead of copy/paste.
