Optical drives read information by using a laser beam to illuminate the surface of an optical disc, such as a CD, DVD, or Blu-ray. The disc is encoded with data in the form of pits and lands, which represent binary information. As the disc spins, the laser detects changes in reflection caused by these pits and lands, converting them into electrical signals that are processed to retrieve the stored information. The drive's optics and sensors work together to ensure accurate reading, even if the disc is slightly scratched or dirty.

Where can I find more information on optical drives?

You can find more information on optical drives on internet review sites or blog post made by users. More information can also be found at local stores.


Why are CD-ROM and DVD drives called optical drives?

It is called an optical drive because the mechanism for reading and writing information is optical (light) based - it uses lasers.


What is the meaning of Optical Disk Drives?

use a laser to read and write data. Optical disks have very large storage capacity but they are not fast as hard disks. There are three basic types of optical disks: CD-ROM, WORM and erasable. DVD-ROM is higher- capacity disc


Do internal hard drives use a laser to read and write data?

No, internal hard drives do not use a laser to read and write data. Instead, they utilize magnetic storage technology, where data is written and read by read/write heads that move across spinning magnetic platters. These heads detect changes in magnetic fields to access and store information. In contrast, optical drives, like CD or DVD players, use lasers to read and write data on discs.


What data cable attatches to the optical drive?

What is Storage media used by optical disc drives?

CD and DVD disks are used by optical disc drives.


What is the purpose of the optical drive?

An optical drive is for reading and possibly writing to optical media such as a CD or DVD. It is pretty much used like any other drive in a computer. Older optical drives could only read data and could not burn disks.


What provides data for optical drives?

Optical drives use laser technology to read and write data on optical discs, such as CDs, DVDs, and Blu-ray discs. The data is encoded in the form of pits and lands on the disc's surface, which the laser beam interprets as binary information. When a disc spins within the drive, the laser reflects off the surface, allowing the drive's sensors to detect these variations and retrieve the stored data. Additionally, the drive's firmware manages the data transfer between the optical disc and the computer.


When were optical drives invented?

According to http://www.answers.com/optical+drives, David Paul Gregg developed an analog optical disc for recording video and patented it in 1961 and 1969.


What purpose do optical drives serve?

An optical drive, or more accurately an optical disk drive (ODD) is medium for storing digital data. Examples are CD, DVD and blu-ray. The characteristic of an optical drive system is that beams of light (typically laser) are used to read the medium.


What are floppy diskette drives?

Floppy diskette drives read and write information to a single rotating disk that can be removed from the drive.


What are optical storage devices are most known as?

An optical storage device is an electro-mechanical unit that can save and retrieve (write and read) information on a special disc medium using a laser light. Optical drives are designed to work with several types of media: CDs ("compact disc"), DVDs (digital versatile disc" or "digital video disc") and Blu-ray discs.
