A protective arrangement for a cassette tape recorder in which a magnetic head has a face side facing upwards, and is located within the recorder. A protective hood covers the face side of the magnetic head, and is rotatably located about a horizontal axis which is perpendicular to the gap plane of the magnetic head. A coiled spring engages the protective hood, and urges it into a closed position. A switch for connecting the recorder to a power supply line, is connected to the protective hood, by a connection located so that upon moving the switch to an ON position, the protective hood is moved to an open position against the action of the spring. When the switch is moved to an OFF position, the movement of the protective hood to its closed position is released. A stop located on the protective hood, enters behind the cassette placed in the recorder in the opening position of the protective hood. Upon release of the closing movement of the protective hood by the switch, it makes contact with the cassette and thereby prevents the closing motion as long as the cassette is not removed from the recorder.
