Abstract
The invention relates to a magnetic tape cassette with a screening shield which is easy to produce and to insert into the cassette and which exhibits a better screening effect than known shields. The screening shield consists of a strip of flexible 'soft' magnetic material which is bent into arcuate shape prior to insertion into the cassette and held in the cassette in straightened or bowed shape under flexural stress by suitably designed holding means in the cassette.
