ABSTRACT:
A head supporting device includes an arm on which an upper magnetic head of a magnetic disk system is mounted, the arm having an adhesion surface to which a first adhesive agent and a second adhesive agent are applied, a carriage on which a lower magnetic head of the system is mounted, the carriage having an adhesion surface to which the first and second adhesive agents are applied, a first gimbal for connecting the upper magnetic head to an internal circuit of the system, the first gimbal having a first adhesion surface so that the first gimbal along with the upper magnetic head attached thereto is fixed to the arm by the first and second adhesive agents, and a second gimbal for connecting the lower magnetic head to the internal circuit, the second gimbal having a second adhesion surface so that the second gimbal along with the lower magnetic head attached thereto is fixed to the carriage by the first and second adhesive agents. In this head supporting device, the adhesion surface of the arm and the first adhesion surface include diagonally cut grooves so that the first adhesive agent flows in the grooves so as to evenly spread over the adhesion surface of the arm and the first adhesion surface, and the adhesion surface of the carriage and the second adhesion surface include diagonally cut grooves so that the first adhesive agent flows in the grooves so as to evenly spread over the adhesion surface of the carriage and the second adhesion surface.
