The tiny indentations on a disc are called "pits." These pits are part of the disc's encoding and represent the digital data stored on the disc, such as CDs or DVDs. When the disc is read by a laser, the transitions between pits and the flat areas (lands) are interpreted as binary data, enabling the playback of audio, video, or other information.

What is a Metal disc used to make a coin called?
The metal disc used to make a coin is called a "coin blank" or, more formally, a "planchet." They also used to be called "flans," but that term is no longer as widely used.
A satellite image is made up of thousands of tiny dots called what?
The tiny dots in a satellite image are called pixels. Each pixel represents a specific color or brightness level and together they form the image that we see.
What are thousands of tiny dots that make satellites images called?
pixels
Polycarbonate discs coated with a reflective metal on which data is recorded using laser technology as a trail of tiny pits or dark spots in the surface of the disc are?
Compact discs (CDs) are made of polycarbonate material and have a reflective metal layer where data is stored as tiny pits or dark spots created by a laser. When the CD is read by a laser in a CD player, the pits reflect light differently, allowing the player to interpret the data encoded on the disc.
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.
The indentations on CDs and DVDs are called?
The indentations on CDs and DVDs are called "pits." These pits are tiny depressions that encode data in a spiral track, which is read by a laser in the disc drive. The areas between the pits are referred to as "lands." Together, pits and lands represent the digital information stored on the disc.
How is a compact disc is a?
CD data is stored as a series of tiny indentations known as "pits", encoded in a spiral track molded into the top of the polycarbonate layer.
What are the opitical discs that store items by using microscopic indentations and the flat areas that are in the middle layer of the disc are called what?
dents
Tiny indentations of the plasma membrane that resemble caves are called?
These indentations are called caveolae. They are flask-shaped invaginations of the plasma membrane that play a role in various cellular processes, such as signal transduction and vesicular trafficking.
What are The triangular indentations used for the script of Sumerians called?
The triangular indentations used for the script of Sumerians is called cuneiform.
What are the indentations in a golf ball called?
Dimples
What are the indentations on a golf ball called?
Dimples.
Is DVDs invention or innovation?
The DVD was a development rather than an invention. It was a high density version of the Compact Disc that was the first of the low cost optical storage devices. Similarly, the Bluray disc is a higher density version of the DVD. The CD itself was a development of optical technologies with low power highly controllable lasers and plastics molding allowing CDs to be printed with accurate, tiny indentations. However, as the CD was the first of its kind, it can certainly be called an invention and so was the invention that lead to the DVD and then the Bluray discs.
How is information stored and recived from a CD?
Information on a CD is stored as tiny indentations, or pits, on the surface of the disc, which represent binary data. A laser in the CD player reads these pits and the flat areas between them (lands) as it spins the disc. The variations in reflection caused by the pits and lands are converted into electrical signals, which are then processed to retrieve the stored information, such as music or files. This process allows for accurate data retrieval and playback.
How do you get scratches of of a GameCube game?
scratches are indents in the disc or where a tiny part of the disc is gone. they cannot be taken off, for they are not a physical object attached to the disc.
What are the advantages and disadvantages of 3.5'' Floppy disks?
Advantages - NoneDisadvantages - TINY TINY TINY Storage- Rubbish size/storage ratio (size of disc)- they are obsolete surelyI built a new PC and didnt include a disc drive because they are pointlessfor the price of a disc drive you can get a 8 gig USB stick
How does a CD store its information?
If you were to look at the shiny part of a disc under a microscope, you'll see that its covered with little dents (called pits, which are small indentations on the surface). The smooth parts of the disc between the pits are called lands.See image: http://www.sonic.net/~ideas/art_mma3.htm…When a laser is shone on the disc and the disc is spun, the smooth parts of the disc, called the 'lands' bounces the laser back onto the sensor.Everytime this happens, it registers as a "1" in computer binary code.However, as it hits a pit (dent), this disrupts the laser beam and thus the laser misses the sensor in the disc drive.This registers as a "0" in binary code.As the disc spins, a sequence of 1's and 0's is produced by the 'pits' and "lands" is produced. The computer analyzes this code and then turns it into data.
