Abstract
A cassette contains an information disc arranged to be rotatable in the space inside the cassette and has an opening in a main wall of the housing to provide access to the disc surface for a pick-up. In order to minimize the area of the opening, while maintaining a wide field of use for the cassette, the opening is arranged asymmetrically relative to a radius of the disc.
