Abstract: An adjusting means for tape guide elements or magnetic heads effects adjustment exclusively in a plane at right angles to a reference surface. A fine adjustment mechanism, in particular a micrometer screw device, provides high accuracy of adjustment over a sufficiently wide range. The adjusting means can be used in any kind of magnetic tape cassette. Advantageous embodiments of such magnetic tape cassettes also form part of the present invention. By using the novel adjusting means, azimuth and skew losses can be compensated for in a simple manner.

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.
