Working Of CD-ROM


CD-ROM

How does a CD-ROM works?

A CD-ROM which is called as Compact Disc - Read Only Memory is a plastic disc with a thin aluminium layer from which music, texts, and other data can be retrieved. Like everything else in the world of computers, these files are also stored in the numeric sequence of 1 and 0. In this case, there are tiny grooves for 1 or none for 0.
CD-ROM Working

A laser beam in the reader scans these grooves, which reflect the laser beam in different ways. From these laser reflections, the chip in the computer or in the CD player deciphers the data present on the CD, which could be music, text, photos or complete programs.
