If you buy a software program, it may come on a CD or DVD, so you also need this drive to install software.

How does an optical disk work?

optical storage, electronic storage medium that uses low-power laser beams to record and retrieve digital (binary) data. In optical-storage technology, a laser beam encodes digital data onto an optical, or laser, disk in the form of tiny pits arranged in a spiral track on the disk’s surface.

What does it mean when a computer has no optical drive?

• The magnetic disk is sensitive to be touched whereas optical disk is not.

What is the function of an optical drive on a laptop?

An optical drive is a type of computer disk drive that reads and writes data from optical disks through laser beaming technology. This type of drive allows a user to retrieve, edit and delete the content from optical disks such as CDs , DVDs and Blu-ray disks. Optical drives are among the most common computer components.

What is the working principal of an optical disc drive?
