What is the difference between an optical drive and an optical disc?

Correct answer: The drive reads or writes the disc while the disc is the storage medium

The governing concept is the difference between a hardware device and a storage medium. An optical drive is the mechanism that uses a laser to read data from, or sometimes write data to, a CD, DVD, or similar disc. The optical disc itself stores the information. Therefore, option B is correct; option A confuses the device with the medium, while C and D describe unrelated functions.
