Abstract: A right parallelepiped cassette is provided with a guide insert as a separate housing part which can be produced and machined separately and very precisely, contains important guide elements of the cassette and can be oriented in a predetermined manner on reference surfaces of the remainder of the cassette housing and fastened thereon. In a particular embodiment, the cassette contains detachably fastened spacing elements for measuring the alignment of the guide elements. The cassette can advantageously be used for any type of recording media in tape or strip form.

Abstract: In a tape cassette possessing symmetrically arranged support liners, a compressive force dependent on the tape roll diameter is exerted by the liner and utilized for centering the roll and the tape. Force/diameter relationships, and embodiments of folded liners for achieving individual forces are described. A novel dynamic liner arrangement can be used in any tape cassette possessing high winding speeds and sensitive tapes, with frequently alternating rewind/playback operation.

Abstract: A guide element for magnetic tapes to be wound in the form of packs on flangeless spools, particularly for tapes in magnetic tape cartridges, which is arranged in a fixed position near the periphery of the pack at maximum pack diameter and provided with a guide surface and guide flanges. Such elements improve guidance of the turn of tape approaching and/or leaving the pack, resulting in a stable and accurate winding on the spool and in undisturbed tape travel.

Abstract: Guide elements for magnetic tapes wound or to be wound in the form of packs on flangeless spools, the guide elements being movable in the plane of rotation of the packs. At least part of the guide elements is located between the pack and the outermost winding and thus constantly guides the tape as it is wound or unwound, resulting in optimal tape guidance and consequently in a stable and accurate winding on the spool.
