Line 1:

'''Optimized Power Control''', also known as '''Optimum Power Calibration''', abbreviated '''OPC''', is a function of a [[compactoptical disc|CD]] or [[DVD]] [[CD recorder|writer]]s.

It checks the proper writing power and reflection of the media in use, calculating the optimum [[laser]] power and adjusting it for writing the particular session. More sophisticated is '''Active OPC''' or '''Running OPC'''. Active OPC monitors writing power and reflection of the media in use, calculating the optimum laser power and adjusting it in real-time, which, in theory, should result in a better quality [[CD/DVD authoring|burn]].
