ABSTRACT:
Azimuth angle of the capstan of a magnetic-tape-cassette apparatus is measured using a cassette having a reference sensor which engages the cassette, and at least one measurement sensor which engages the cassette at a location spaced axially from the reference sensor. The measurement sensor includes an electrical measuring element such as a strain gauge which provides an indication of the position of the element with respect to the reference sensor. The azimuth angle can readily be computed using the known axial spacing between the sensors and the electrical value transmitted from the measurement sensor.
