What is the full form of CDS?
The full form of CDS is the Compact Disc - Read-Only Memory or Compact Disc - Digital Audio. It is a digital optical disc data storage format.
How do data represent on an optical disc?
All digital data is represented as one's and zero's. The actual physical representation of data on an optical disc - assuming you are talking about CD's - is called pits and lands.
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 the way data is stored in the Windows OS?
Data is stored on the hard disc. The more memory hard disc has the more data can be stored.
Which optical disc format supports data capacity of 25GB?
Single-sided, single-layer Blu-ray disc.
What type of optical disc that can hold 4.7gb or more data?
A DVD can hold up to 50 GB of data.
What is the process of writing on a optical device?
To write on an optical disc, a laser beam is used to heat up a photosensitive dye layer on the disc. The heated dye changes its physical properties, creating a pattern of 0s and 1s that represent data. This process is known as burning or recording data onto the disc.
What are are thin circular discs made out of polycarbonate topped with layers of materials and coatings used to store data and protect the disc?
Optical Discs
What is the ultraviolet disc and how do they work?
"Ultraviolet discs" may refer to ultraviolet light-sensitive data storage optical discs used for archival backup. These discs utilize a special coating to protect the data layer from UV light degradation. To use them, you need a compatible optical disc drive that can read and write data to these discs.
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 work optical disk?
We all use optical drives on our computers. However, have you ever wondered how on earth it is possible to store huge amount of data on a CD (compact disc) or DVD (digital video disc) or how an optical drive such as a CD ROM drive works? Read on if you are interested to know. Anoptical disc such as a CD or a DVD has basically 3 layers on it. The non-silvered side is the layer on which you can affix a label on the CD for identification of its contents. It also serves to protect the data on the disc. The middle layer is the reflective layer. It is sandwiched between the non-silvered layer and the silvered layer on the other side of the disc. The reflective layer is the one that stores all the data in microscopic pits in grooves on an optical disc. This is why a slight scratch on the silvered surface of a CD does not entirely damage its property to store and display data. However, what the scratch does is to impede data reading on an inserted CD by blocking the beam of light from a laser on the optical drive. This is also one reason it is recommended for you to use a soft marker for writing the label description on the non-silvered side of the CD. A DVD is an improved version of an optical disc that enables you to store significantly more data on it than is possible to store on a CD. While a CD can store upto 700 MB (megabytes) of data on it, a single layer DVD can store 4.3 GB (gigabytes) of data on it. A double layered DVD can store 8.7 GB of data on it. As opposed to a single layer optical disc which has only one reflective layer, a dual layered optical disc has two reflective layers. The top reflective layer is semitransparent to allow the laser on the optical drive to read the data on the inner reflective layer by a change of focal length. While you use Nero or other burning software to burn the data on the reflective layer on a CD or DVD inserted in the respective CD or DVD writer optical drive, mass-produced commercial software is not burned on optical discs that way because there exists a quicker method. It involves the use of a mold to stamp press the data in pits on the reflective layer in an optical disc. When you insert a data CD or DVD in a CDROM or DVDROM drive, a laser on the optical drive focuses a beam of light on the reflective layer on the optical disk. The beam focused on pits is scattered, whereas that on lands is reflected back with higher intensity and stored in a photo diode array. The diode array is used to read and analyze the data. CDROM optical drive technology is now obsolete and has given way to DVDROM optical drive technology.
Is a optical drive a input device?
It's input I think, not that sure, but I just know that it reads data from a disc and then views them onto the computer screen. :)
