Optimized Power Control, also known as Optimum Power Calibration, abbreviated OPC, is a function of optical disc recorders. 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 burn.

Property Value
dbo:abstract
  • Optimum Power Calibration (OPC) es una función de las grabadoras de discos ópticos (CD, DVD, etc). La función OPC es invocada al inicio del proceso de grabación para determinar la intensidad apropiada del rayo láser al momento de grabar. Para lograr esto la grabadora, antes de comenzar la grabación, escribe en una zona del disco especialmente reservada para ello denominada Power Calibration Area (PCA), luego calcula la reflectividad en esa área y realiza los ajustes correspondientes a la intensidad del láser. Existen versiones más sofisticadas, como Active OPC o Running OPC, que consisten en invocar la función OPC en tiempo real conforme transcurre el proceso de quemado, lo que —en teoría— resulta en una mejor calidad de grabación.
