The images you see on your monitor are made of tiny dots called pixels. At most common resolution settings, a screen displays over amillion pixels, and the computer has to decide what to do with every one in order to create an image. To do this, it needs a translator -- something to take binary data from the CPU and turn it into a picture you can see. Unless a computer has graphics capability built into the motherboard, that translation takes place on the graphics card.

A computer memory card works by storing the information and processes that are taking place on a computer in present time. Discover how memory cards on computers interact with the CPU using insight from a computer and technology specialist in this free video on computers.

It can cost between $10.00 and $40.00
Some companies that makeDVD/CD-ROM drives are:
Microsoft, Mac OX, Linux.
A small rig moves a laser along the CD, the laser reads binary data from the grooves in the CD and the drive's software interprets the results.
There's three main parts to an optical disk drive:
1. Motor
2. Lens/Laser/Senor
3. IC Board

The motor spins the actual disk, precisely regulating the speed at which the disk rotates.The lens apparatus shines a laser at the surface of the spinning disk. The laser bounces off the reflective surface of the disk, and hits the sensor. The sensor reads the signal of the laser, and sends it to the IC Board.
The IC Board sends electronic signals to and from the computer and CD/DVD drive.
Thus, the information on a CD/DVD is read by the drive, and sent to the computer.

The cyanine & phthalocyanine dyes used in CD-Recordable discs are photosensitive organic compounds, similar to that used in making photographs (which explains why companies like Kodak and Fuji are in this business.) When a CD-R isrecorded the dye is heated by the writing laser and becomes opaque (or absorbtive) through a chemical reaction to the heat (and possibly to some mingling with nearby semi-melted polycarbonate according to some sources), so it's not likely that any process will be developed to reverse the process and make previously burned CD-Rs reusable.
