Question 17

What is the major difference between optical and magnetic discs?

Answer

Optical Discs use laser technology to read and write data. The data is encoded on the disc surface as tiny pits and lands, which are read by a laser beam.

Magnetic Discs use magnetic fields to store data. The data is recorded on a magnetic surface, such as that found in hard disk drives, in the form of magnetic patterns.
