DISPOSITIF D'AVANCEMENT ET DE POSITIONNEMENT EN PARTICULIER EN VUE DE LA RECEPTION D'UNE TETE MAGNETIQUE SERVANT A L'ENREGISTREMENT ET A LA LECTURE D'UN DISQUE MAGNETIQUE SOUPLE

摘要

In the case of an advancing and positioning mechanism, in particular for moving a magnetic head serving for the recording and reading of a flexible magnetic disc, the moving band (4) rolls on the drum fitted on the shaft of the advancing motor. As a result, a plastic carriage (5), which carries the magnetic head (6), is taken along with it. The plastic carriage (5) slides on a rod (7) and bears against a supporting rod (8). Due to the forces occurring in the sections of the moving band (4), the plastic carriage (5) is prismatically guided if a suitable geometric design is chosen. <IMAGE>
