What is Optical disc drive?
[[Image:Optical Drive.jpg|thumb|250px|Putting a disc in a drive]] An '''optical drive''' is usually a [[Compact disc|CD]] drive or [[DVD]] drive. Optical means it uses [[wikt:lens|lenses]]. The drive uses a light called a [[laser]]. A laser is the most exact and powerful sort of light but the laser in the drive is very, very small. The CD or DVD disk is similar to a mirror and the laser light reflects off it. The disk has very small ([[wikt:microscropic|microscopic]]) [[code]]s written on it. The drive has a very small [[camera|camera lens]] beside the laser which can read the codes. Another part of the drive is plugged in to the computer by a wire (inside) and the code goes through the wire as a signal to the computer. ==List of optical drives== *[[Compact Disc|CD]] drive *[[DVD]] drive *[[Blu-ray Disc]] drive *[[HD DVD|HD-DVD]] drive *[[Laserdisc|LaserDisc]] drive {{tech-stub}} {{Emerging technologies}} [[Category:Computer science]] [[Category:Machines]] [[Category:Electronics]]
