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.
