- Compact Discs (CDs) store data in the form of tiny indentations on a smooth surface. A CD player uses a laser beam to read these indentations and convert them into digital data123. CD-ROM drives employ a near-infrared 780 nm laser diode, which is directed onto the disc via an opto-electronic tracking module, which then detects whether the beam has been reflected or scattered2. When the CD player or disc drive is turned on, the internal motor of the device enables the compact disc to rotate at a significant high speed, between 200 and 500 rotations per minute. This causes the internal semiconductor diode laser to be powered up and begin scanning the disc’s tracks from the centre outward4.Learn more:✕This summary was generated using AI based on multiple online sources.

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.www.britannica.com/technology/CD-ROMWhen the CD player or disc drive is turned on, the internal motor of the device enables the compact disc to rotate at a significant high speed, between 200 and 500 rotations per minute.
