optical drive

CD/DVD reading hardware

An optical drive is a computer component that reads data from discs—CDs, DVDs, or Blu-rays—using a laser beam.

Most can also write data to blank or rewritable discs.

Once standard in computers, optical drives have become less common as streaming and flash storage have replaced physical media for software distribution and entertainment.
