What are smooth and level areas on an optical disc called?
are smooth and leve areas on an optical disk
Which are smooth and level areas on an optical disc?
Lands
What type of storage stores data as microscopic light and dark spots on the disc surface?
optical
Can the rewritable optical disc be infected by virus?
If you burn infected files onto an optical disc then those files remain infected and would remain on the optical disc permanently.
How is the Optical disc similar to the compact disc?
A compact disc is a type of optical disc. "Optical disc" is an umbrella term for any type of storage media which uses optical technology (as opposed to magnetic) for data storage. This includes but is not limited to DVDs, CDs, H-DVD, blu-ray, laser discs CDRW's, and DVDRW's
What is Storage media used by optical disc drives?
CD and DVD disks are used by optical disc drives.
How do you use optical disc?
An optical disc has one long spiral track of data. Along the track there are areas that are reflective and areas that are not. A laser is shone along the track, the reflective areas are read as binary 1's while the non-reflective areas are read as binary 0's. CD-R's and DVD-R's have a dye layer that is used to write your own CDs and DVDs with the appropriate hardware.
What are the types of optical disc?
types of optical disc drive are: cd,dvd,blueray,cdr,cdrw,dvdrw,mp3,mp4
What is the most important part of a CD?
The most important part of an optical disc drive is an optical path, placed in a pickup head (PUH),[1] usually consisting of semiconductor laser, a lens for guiding the laser beam, and photo-diodes detecting the light reflection from disc's surface.
How does a DVD drive work?
A DVD drive uses a laser and an optical lens to read the surface of the disc itself, which contains several pits that contain data. If the laser hits pits, it is a 1. If not, it is a 0. The laser, containing data, comes back from the mirrored disc surface and into the optical lens, reading the information and therefore changing it into graphics, audio, and useful information.
CDs and DVDs are durable storage media because their storage technology essentially etches data onto the disc surface?
optical storage technology
How does an optical disk drive work?
An optical disc drive reads a disc by shining a laser on it and detecting the reflected beam. The reflectivity of a disc varies across its surface, which determines the intensity of the reflected beam. Photodiodes detect this reflected beam and produce electrical signals, which are interpreted as data.
