SUMMARY

A Compact Disc (CD) functions by using optical storage technology to encode data in the form of pits and lands on its surface. When a CD is played, a laser reads these variations to retrieve audio, video, or image files. The data is stored in a digital format, typically as MPEG for video and JPEG for images. For a comprehensive understanding, users are encouraged to consult dedicated resources rather than relying solely on forum discussions.

PREREQUISITES
  • Understanding of optical storage technology
  • Familiarity with digital data formats such as MPEG and JPEG
  • Basic knowledge of how lasers read data from physical media
  • Ability to interpret technical diagrams related to CD structure
NEXT STEPS
  • Research the principles of optical data storage technology
  • Explore the differences between various digital formats like MPEG and JPEG
  • Learn about the mechanics of laser reading in optical drives
  • Examine technical diagrams illustrating CD data encoding
USEFUL FOR

Students, educators, and technology enthusiasts interested in understanding the mechanics of optical media and digital data storage.

i just wanted to know how a CD works! how do we see a movie stored in it? and how does it store pictures and allows us to see it? what form is it stored?..... :confused:
 
Physics news on Phys.org
I tried this link which was returned from a Google search "CD how it works"
Read that (and some other stuff) and then come back with some specific questions. People have already prepared diagrams and explanations for people to use. Using a Forum is not an efficient way to find out this sort of thing. Google can be good value.
