CdrCDR
Recordable Compact Disk (CD-R) is a blank CD with the ability to be recorded onto. The unit that is used to write data to these blank CD�s is called a CD Writer or �Burner.� This unit is not unlike a normal CD drive, the difference being that it has two lasers one invisible, one visible. The invisible, is used for writing data onto the surface of the blank CD. The visible, is for reading information off the CD. The unit itself is currently for use in a computer system only, and therefor must be installed like a normal CD drive. The two CD drives then run coherently to copy data from one cd to another.
CDR was introduced around 5 years ago, but really only became affordable over the last two years. This has increased its popularity to an extent where its use has started to spark issues relating to the reproduction of copyrighted material. This has started to have a negative economical effect on the music industry. I will address the issue of piracy later in this report. CDs have become a cost effective industry standard when it comes to storing data.

Factors influencing the development of CDR
CDs have become the standard for all forms of media, be it audio, visual or multimedia. Until recently, there has been no economically viable way to create your own CD�s at home. So the first CD Writers were introduced, made by Panasonic, costing over $900. Like most things, an increase in demand caused the recommended retail price to drop to the point where they are almost as low as $400. With this decline in price, CD Writers have become more affordable. The acknowledged intent is that people will use it for personal use, mainly to backup data, but this is not always the case, as the ease at which someone can copy a CD and sell it for their own profit has become a major issue. The act of reproducing copyrighted material is commonly known as Piracy.
Piracy is widespread, economically effecting record companies and producers alike. The laws in relation to copying CDs are not specific at all. In America a blank CD has a $10 levy incorporated into the price, this money goes toward record companies and producers, and entitles people to copy CDs for their own personal use. In Australia however, there is no levy so no such rule applies. In the manual of the...
