Abstract: A recording and/or reproducing apparatus comprising a cassette receptacle (5), into which a cassette (3) can be inserted manually in a direction of insertion (4) and which comprises at least one member (15) for retaining a cassette, which member is at least partly movable in the direction of insertion from an initial position to an operating position and can be coupled to a cassette in its initial position. Said member is coupled to a drive lever (22) via a pin-slot linkage (21) in order to be driven by a motor (27) via a drive mechanism (26), the pin (40) cooperating with a longitudinal wall (42) of the slot (39) when the drive lever (22) is driven by the motor. In its other longitudinal wall (43) the slot (39) has a recess (44) which extends substantially in the direction of insertion.

Abstract: A magnetic-tape cassette having an electrically conductive cylindrical tape guide which contacts the base side of the magnetic-tape, and has an axial recess accessible from the exterior for grounding the tape. An electrically conductive resilient element is arranged in the cassette, with one portion of the element positioned against the coating side of the magnetic-tape at the location of the guide, and the other side of the element in conductive electrical contact with the tape guide.

Abstract: A cassette tape recorder including a device for making index marks on a strip denoting the position of magnetic tape relative to a magnetic head, the marking strip being on a cassette exterior surface and having magnetically alignable particles by which visible, magnetically erasable marks can be made. The marking device includes a controllable magnet for selectively magnetizing an element made of a soft magnetic material which conducts flux to the strip.In a magnetic tape cassette adapted for such apparatus a strip with magnetically alignable particles is arranged on at least one major flat wall of the cassette, so as to be readily visible.
