ABSTRACT:
A molded plastics cassette case for rotatably accommodating a flexible magnetic disc (preferably a nominal 3.5 inch diameter microdisc) includes at least one, and preferably several, drag finger integrally molded therewith. The drag finger has a base end which is structurally unitary with the cassette case, and a free terminal end, opposite to the base end, which imparts frictional drag resistance to the central hub of the flexible magnetic disc. In this manner, more reliable rotational velocity of the spinning magnetic disc may be achieved without the need for separate liner and lifter structures associated with conventional microdisc cassettes, thereby simplifying cassette construction and assembly.
