A cassette tape recorder for use with a cassette which has at least one opening on its wide side, through which opening, upon the insertion of the cassette into the device, there can be inserted at least one winding mandrel for engagement in the core of the tape spool, the cassette having at least one opening in one of its narrow sides, in which last mentioned opening, after the setting of the cassette on the winding mandrel by means of a feed device (which feed device can be transferred against the action of a spring into the operating position by means of a first control element and which feed device is again releasable out of this operating position by means of a second control element), the magnetic head is insertable in a direction perpendicular to the axis of the winding mandrel for the purpose of recording or playback, and which contains means which prevent a mechanical stressing of the magnetic head if with an inserted magnetic head, attempt is made to take the cassette from the device. The control element for release of the feed device for the magnetic head is moveable in the direction of the grabbing movement of the hand for the inserted cassette and is arranged bordering directly contiguous to the cassette in a manner such that the cassette can only be grabbed after the control element has been moved.
