FAQ: How Does Cd-rom Work?

A CD-ROM drive uses a low-power laser beam to read digitized (binary) data that has been encoded in the form of tiny pits on an optical disk. The drive then feeds the data to a computer for processing. The standard compact disc was introduced in 1982 for digital audio reproduction.

How does CD-ROM store data?

Data is stored on the disc as a series of microscopic indentations called “pits”, with the non-indented spaces between them called “lands”. A laser is shone onto the reflective surface of the disc to read the pattern of pits and lands. This is converted into binary data.

How does a CD drive work?

The CD drive shines a laser at the surface of the CD and can detect the reflective areas and the bumps by the amount of laser light they reflect. The drive converts the reflections into 1s and 0s to read digital data from the disc. A CD-R disc needs to allow the drive to write data onto the disc.
