Data is stored on optical discs using a laser to either melt the disc material or change the color of embedded dye.
An optical disc (OD) can be defined as a small, circular and digital-disc which is designed and developed to be used for the storage of computer data, especially by using a laser beam technology.
For instance, a compact disc (CD) is able to store digital data because it is manufactured through the use of polycarbonate (a tough-brittle plastic) with one (1) or more metal layers.
In this context, we can reasonably infer and logically deduce that data is typically stored on optical discs by using a laser to either melt the disc material or change the color of embedded dye.
