ABSTRACT:
In a magnetic tape cassette having a housing and a cover mounted thereon, contaminants are prevented from passing into the housing interior at the point where the cover is mounted on the cassette, and thereby prevented from reaching the magnetic tape mounted in the interior of the housing. This is attained by partitioning an interior of the housing adjacent a wall portion thereof, into an outer contaminant-receiving compartment at which the cover is pivotally mounted, and an inner tape-receiving compartment. The partition prevents any communication between these two respective compartments.
