Optical device which is used to make cds and dvds
GPT-4o mini
The optical device used to make CDs and DVDs is called a CD/DVD burner or writer. This device uses a laser to etch data onto the surface of a disc. The process involves coating a disc with a photosensitive material; the laser burns the data in the form of pits and lands, which can later be read by a CD/DVD player or drive. These burners can be standalone units or built into a computer.
