    摘要： A magnetic disc apparatus having a magnetic disc on which information is recorded, a magnetic head and a magnetic head supporting mechanism. The magnetic head supporting mechanism includes a slider having the magnetic head mounted thereon, a load beam having an arm mounting portion and a pivot, and a gimbal having a mounting portion on which the slider is mounted, two flexible finger portions spaced from the load beam and supporting 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 two openings formed therein in proximity to the pivot which enable viewing of a back surface of the mounting portion which is opposite to a surface of the mounting portion of the gimbal on which the slider is mounted.

    摘要： If a large external impact is applied to a magnetic disc apparatus, a slider jumps from a disc surface and rotates. When the slider jumps and rotates, its edges re-contact the disc surface to damage this surface. To reduce the rotation angle of the slider to control its position if an impact is effected, the present invention provides a roof on a load arm to reduce the contact angle at which the slider contacts the disc surface in order to relax the impact upon a contact.

    摘要翻译： 如果对磁盘装置施加大的外部冲击，则滑块从盘表面跳转并旋转。 当滑块跳转并旋转时，其边缘会重新接触光盘表面以损坏该表面。 为了减小滑块的旋转角度以控制其位置，如果发生冲击，本发明在负载臂上提供一个屋顶，以减小滑块与盘表面接触的接触角，以便放松对接触的冲击 。
