ABSTRACT:
A magnetic head slider support device is provided for use in a magnetic disc apparatus. The device comprises a magnetic head, a head slider having the magnetic head, a support arm portion which supports the head slider, and a gimbal spring fixed to a forward end of the support arm portion to attach the head slider. The support arm portion includes a load beam support portion for supporting the head slider and gimbal spring. A load beam plate spring portion applies a force to the head slider, towards a recording surface. A pivotal support arm portion has a pivotal movement center, about which the device pivots. The pivotal movement center pivotally supports the load beam support portion and the load beam plate spring portion at the rear of the support arm portion. The load beam support portion, the load beam plate spring portion and the pivotal support arm portion are formed from a single piece of material of constant thickness. The pivotal support arm portion has a flat face and a side face. The side face has a rib formed by folding a part of the flat face approximately perpendicular to the remainder of the flat face. A cut-out portion having a rib is formed in the flat face. The cut-out portion has first and second sides. The first side is closer to the pivotal movement center than the second side, and is smaller than the second side.
