Abstract

An in-line type magnetic head supporting apparatus of the present invention including a first fixed part secured to a magnetic head slider mounted with a magnetic head in a floatable manner, a second fixed part secured to a load beam which presses the magnetic head slider toward the magnetic disc, and a gimbal mechanism comprising a spring part connecting the first and second fixed parts and enabling the pitching and rolling movements of the magnetic head slider in the radial direction of the magnetic disc, and further includes a restricting mechanism for preventing the sideslip of a pivot formed on the first fixed part as a fulcrum for pitching and rolling movements. Furthermore, in order to increase the flexural rigidity of the spring part of the gimbal mechanism in the radial direction, its lateral length is enlarged and slits are formed in the spring part to reduce the torsional rigidity thereby to prevent the inteference of the pitching and rolling movements.
