ABSTRACT:
In a tape cassette, a rotary movement of a reel or hub can be visualized in a technical and aesthetic manner by means of a completely or partly transparent cover above and/or below the reel or the hub. Advantageously, the cover contains at least one space and the reel or the hub at least one contrasting pattern, for example with respect to the shape and color of the cover. The pattern/cover combination can be used for all cassettes containing recording media, in which a movement of the recording medium, in particular of a magnetic tape, of a magnetic disk, of a film, of an optical disk, etc., takes place.
