What is Initialize? What is BCA?

Initialize? To make possible to write digital data, Rapid Cooling Melting Amorphous For Writing Point Point Crystallize Te m p Time

Initialize? Slow Cooling change to Crystalline State for drive data Writing Amorphous Melting Point Point Slow Cooling Crystalline State Crystallize Te m p Time

Initializing by Initializer Objective Lens Laser Beam Crystalline Crystalline State Laser Spot Amorphous

BCA? Different ID Code per Discs Identify Copy protect, Enjoy Contents Written & Marked by BCA Maker
