Question

what is the behind the screen working of cd burning? how a cd burning program works? what is the basic of cd writing?

Answer 1

A CD is a fairly simple piece of plastic, about four one-hundredths (4/100) of an inch (1.2 mm) thick. Most of a CD consists of an injection-molded piece of clear polycarbonate plastic. During manufacturing, this plastic is impressed with microscopic bumps arranged as a single, continuous, extremely long spiral track of data. We'll return to the bumps in a moment. Once the clear piece of polycarbonate is formed, a thin, reflective aluminum layer is sputtered onto the disc, covering the bumps. Then a thin acrylic layer is sprayed over the aluminum to protect it. The label is then printed onto the acrylic
CD burners darken microscopic areas of CD-R discs to record a digital pattern of reflective and non-reflective areas that can be read by a standard CD player. Since the data must be accurately encoded on such a small scale, the burning system must be extremely precise. Still, the basic process at work is quite simple.
Reading
The CD burner has a moving laser assembly, just like an ordinary CD player. But in addition to the standard "read laser," it has a "write laser." The write laser is more powerful than the read laser, so it interacts with the disc differently: It alters the surface instead of just bouncing light off it. Read lasers are not intense enough to darken the dye material, so simply playing a CD-R in a CD drive will not destroy any encoded information.
Writing
The write laser moves in exactly the same way as the read laser: It moves outward while the disc spins. The bottom plastic layer has grooves pre-pressed into it, to guide the laser along the correct path. By calibrating the rate of spin with the movement of the laser assembly, the burner keeps the laser running along the track at a constant rate of speed. To record the data, the burner simply turns the laser writer on and off in synch with the pattern of 1s and 0s. The laser darkens the material to encode a 0 and leaves it translucent to encode a 1.
that mean that the program send all the darta like a RAW data to specific device

Answer 2

CD's are discs with an alluminum foil layer covered by a plastic layer. When a cd reader of any kind reads a cd, it sends a small laser beam to the disc. Depending on whether or not there is a notch in the plastic, there may or may not be a laser beam fired back at the laser detector. When a cd burner "burns" cd's, it fires stronger lasers at the cd very quickly and constantly turning it on and off. The burner starts at the middle of the cd and as it does its works around and around, the motor moves the laser so it "burns" on a different part of the cd. The cd burner makes very very tiny notches on the plastic layer, so sometimes the cd reader laser will strike the alluminum. The cd spins very quickly, so the notches change whether or not the laser will bounce back and strike the laser detector near the laser itself. The notches make 0's and 1's, so it is in binary code, which is used in computers, which store data, including sound files, so there is sound stored on the cd which is then converted to sound which comes out the speakers/headphones when read.
