Many have wondered about it. People pop a CD into a drive, hear some tiny clicks and faint whirring, and come out with a duplicate. Copying from CD to CD can be astounding. And it happens everyday. Many people have done it hundreds of times without really understanding it. The first key is to understanding what a compact disk is.
Compact disks are optically read and used for the storage of all types of data. They are 1.2 mm thick and 120 mm in diameter. They can hold up 80 minutes of data. Within the plastic coating there is an aluminum alloy sheet with tiny indentations called "pits". The areas in between the pit are known as "lands". These are what makes a disk readable as a laser precisely measures and gauges the distance between them resulting in an output of sound, video, photos and text.
A CD "writer" is needed to copy disks. The laser in the writer is able to heat and manipulate the alloy sheet and create a set of pits and lands that are actually code for data. Not all disks and drives are able to make copies. A re-writable disk, known as a CD-RW, and a drive that has the writing function are the ones needed to perform this task.
The earlier generations of disk players and readers had difficulty reading the RW disk. In recent years the newer, more advanced generations read them with little difficulty.
Many store bought computer systems now have the software and hardware necessary for CD copying already factory installed. The practice of copying, or "burning" CD's is now very common place as it has added versatility to many facets of life. If a family wants to send photographs or videos to loved ones they can do so with a copied disk. In the business world it is an way to pass along important documents.
It is much easier to accomplish this task with systems that have two disk drives installed, one for writing and one for reading. Many of the newer drives can have both. However, duplication is still possible only with one drive. Many people are fond of copying music from CD's and creating mixed varieties for car travel.
Copying data from CD to CD is as easy today as it was decades ago for VCR/VHS and stereo cassette tapes. The added benefits are a much cleaner, crisper output of sound and images. Many people consider this an easy function. Even those who are not computer literate can learn to accomplish with little difficulty.
