The most important advantage of a video disk is Potential
capacity.
There are many variations on the DVD theme. There are two
physical sizes: 12 cm (4.7 inches) and 8 cm (3.1 inches), both 1.2 mm thick.
These are the same form factors as CD. A DVD disc can be single-sided or
double-sided. Each side can have one or two layers of data. The amount of video
a disc can hold depends on how much audio accompanies it and how heavily the
video and audio are compressed. The oft-quoted figure of 133 minutes is
apocryphal: a DVD with only one audio track easily holds over 160 minutes, and
a single layer can actually hold up to 9 hours of video and audio if it's
compressed to VHS quality.
Storage capacity refers to how much disk space one or
more storage devices provides. It measures how much data a computer system may
contain. For an example, a computer with a 500GB hard drive has a storage
capacity of 500 gigabytes. A network server with four 1TB drives, has a storage
capacity of 4 terabytes.
