Every DVD has a portion of space set aside for video and space set aside for data. The space set aside for data is known as Read Only Memory or ROM.

These DVD-ROM tracks are portions of a DVD that are invisible to a standard DVD player. When the disk is inserted into a DVD-equipped computer however, the track becomes accessible just like any computer media disk. It is easy to include forms, Flash videos, PDF files, e-books, lists of linked web resources, computer programs, or just about any other digital resource you can think of.
