Magnetic shielding spring

摘要

A magnetic tape cassette comprising a housing having an apertured wall to admit a magnetic head, tape guiding means, tape pressure means provided opposite to the aperture and a leaf spring adapted to press the tape pressure means against the tape when a magnetic tape is present in the cassette. The leaf spring consisting of one strip of a soft-magnetic metal alloy having an amorphous structure also serves as a magnetic shielding.
