   Optical storage is the storage of data on an optically readable medium. Data is recorded by making marks in a pattern that can be read back with the aid of light, usually a beam of laser light precisely focused on a spinning optical disc .

   What is optical storage and how does it work?

   • What is optical storage? Optical storage is any storage type in which data is written and read with a laser. Typically, data is written to optical media such as compact discs (CDs) and digital versatile discs (DVDs).

   How do optical disks work?

   • Optical disks rely on a red or blue laser to record and read data. Most of today's optical disks are flat, circular and 12 centimeters in diameter. Data is stored on the disk in the form of microscopic data pits and lands. The pits are etched into a reflective layer of recording material.

   How long do optical storage devices last?

   • Optical storage devices last very long if you keep them safe and handle them properly. Also, the data on them can be very stable. Speaking of their data stability, power outage or magnetic disturbances can not destroy the data in these devices. As a matter of fact, some DVDs can retain data for 10 to 20 years or even longer.

   What are the advantages of optical storage over other storage media?

   • One of the biggest advantages of optical storage over other storage media is durability. Optical discs are not vulnerable to data loss due to power failure like volatile memory, and they're not as subject to wear as non-volatile memory (NVM) such as HDDs and flash SSDs.

   What is the difference between optical disks and other storage media?

   • Despite these difference, optical discs for storage are still made up mostly of plastic and can be produced in bulk, making them cheaper to manufacture compared to other storage media. The biggest disadvantage of optical storage is disk capacity.

   What type of data is stored on an optical disk?

   • Most of today's optical disks are flat, circular and 12 centimeters in diameter. Data is stored on the disk in the form of microscopic data pits and lands. The pits are etched into a reflective layer of recording material. The lands are the flat, unindented areas surrounding the pits.

   An optical disk drive uses a laser beam to read the data from the disk as it is spinning. It distinguishes between the pits and lands based on how the light reflects off the recording material. The drive uses the differences in reflectivity to determine the 0 and 1 bits that represent the data.
