It is a compact disk. Or it could be anything under optical disk drive.
what storage media uses laser beams to create three-dimension storage image
holographic storage
Laser printers use a drum and toner in the printing process.
An SDHC card uses flash memory technology for data storage and retrieval.
A CD drive uses an infrared laser to read the data. An ultraviolet ray is used in Blu-Ray players, which gives them a much higher storage capacity.
A laser printer uses a dry toner powder in a sealed cartridge.
The Death Star uses a laser to destroy Alderaan.
The Death Star uses a laser to destroy Alderaan.
A secondary storage medium that uses a high-intensity laser for data recording is an optical disc, such as a CD, DVD, or Blu-ray disc. These discs store data in the form of tiny pits and lands on their surfaces, which are read by a laser in optical drives. This technology allows for the storage of large amounts of data in a compact format, making optical discs a popular choice for music, movies, and software distribution.
It is the class of laser that the first Death Star uses.
The scanner that reads the barcodes uses a laser.
LASER is Light amplification by stimulated emission of radiation. As far as I have understood, Solid State laser is a macroscopic form of diode laser. Thus a small semiconductor diode is similar to a solid state laser except for the mechanism of lasing and size.
