| Compact Disc | Compact Disc – this is the generic term that is often used to cover all forms of 120mm polycarbonate optical media discs with a capacity of approximately 600MB’s. Compact Discs are made from a 1.2 mm thick disc of polycarbonate plastic, with a thin layer of aluminum to make a reflective surface. The most common size of CD-ROM disc is 120 mm in diameter, though the smaller Mini CD standard with an 80 mm diameter, as well as numerous non-standard sizes and shapes (e.g. business card-sized media) are also available. CD’s are commonly used for music and audio reproduction, but can also be used to distribute data files, software applications and other types of multimedia. |
