A DVD disc looks like today's CD: it is a silvery platter, 12 cm in diameter, with a hole in the centre. Like a CD, data is recorded on the disc in a spiral trail of tiny pits, and the discs are read using a laser beam. Here is where the similarities essentially stop. Comprised of two 0.6 mm thick discs bonded together, a DVD disc has a much larger capacity than a normal audio CD. It can store anywhere from 4.7 to 17 GB of data, your normal audio CD only 680 MB. DVD's larger capacity is achieved by making the pits smaller and the spiral tighter, and by recording the data in as many as four layers, two on each side of the disc.
In its simplest version, a DVD disk with a capacity of 4.7 billion bytes can hold up to 133 minutes of studio-quality video. In addition, audiophiles are well served with the equally impressive sound quality.
