ABSTRACT:
A suspension member for a magnetic head and for use in a floppy disc drive mechanism and for supporting the head for contact with the surface of a disk. The suspension member has in it a group of openings in the form of Archimedes spirals. The suspension member is constructed to have the characteristic of having stability in that any deviation out of its plane is along a central axis normal to the surface of the member; a predetermined loading force producing a predetermined deflection. Associated with the member is a magnetic shield secured to the suspension member for shielding the magnetic head.
