ABSTRACT:
A magnetic disc apparatus having a magnetic head supporting mechanism which includes a slider, a load beam having a spring portion and a pivot, and a gimbal having a mounting portion on which the slider is mounted. The gimbal has flexible finger portions spaced from the load beam which support the mounting portion so that the slider is rotatable with respect to the pivot, and a base end portion which is joined to the load beam. The load beam has elongation portions extending with respect to both sides of the pivot and being connected together in a proximity of a tip end portion of the flexible finger portions so as to be spaced from the pivot of the gimbal and for delimiting a window. The pivot is provided on a projection portion of the load beam which projects in the window from a spring portion side of the window.
