All Optical media (CD, DVD, Blu-Ray etc.) have pits and lands. These are microscopic and represent the binary information of the data stored on the disc. A land is reflective and reflects the laser into a sensor to register it as a I, but when the light hits a pit, it shatters and no reflection is received, thus a O is registered. There is much confusion as to which is a pit and which is a land, even some professional texts get it wrong, but this is the way I was educated.
What else can I help you with?
The surface of a CD stores data as pits and?
Lands
What uses pits and lands to store information?
Optical discs, such as CDs and DVDs, use pits and lands to store information. Pits and lands are variations in the physical surface of the disc that represent binary data (0s and 1s) which is read by a laser during playback.
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.
On a CD the area that separates the pits is a mountain?
Flats, or lands.
What stores items by using microscopic pits and lands in its middle layer and is read by a laser beam?
A compact disc (CD) stores data by using microscopic pits and lands in its middle layer called the polycarbonate layer. These pits and lands are read by a laser beam in order to retrieve the stored information.
What are the flat spots on a CD called?
The flat spots on a CD are called pits and lands. These pits and lands are etched onto the surface of the CD to store digital information in the form of binary code.
What do CD's use to store data on the disks surface?
Pits and lands
What are the words used to describe where info is stored on a CD?
Pits and lands
What is a pitpit?
The recessed area on a CD or DVD where data is stored. CDs and DVDs store data in lands and pits. The lands represent 1 and the pits represent 0 in binary computing. The bits are read by the disc drive that uses a laser beam to distinguish between the lands and pits based on the amount of scattering or deflection that occurs when the beam of light hits the surface of the disc
What does CD's use to store data on the disk's surface?
Compact Discs (CDs) store data on their surface using tiny pits and lands that are encoded in a spiral track. These pits represent binary data, with pits corresponding to binary "0" and lands representing binary "1." A laser in the CD player reads these variations in height as it spins the disc, allowing the retrieval of the stored information. The reflective layer beneath the surface helps in detecting the changes in light intensity caused by the pits and lands.
