Abstract: In one implementation, the presently disclosed technology teaches an apparatus with a head attached to an end of a baseplate. The baseplate includes a tilted section that causes a torsion axis of the baseplate to pass near the head. In another implementation, the presently disclosed technology teaches an apparatus with a load beam attached to a baseplate. The apparatus also includes a head attached to an opposite end of the load beam from the baseplate. The baseplate includes a mass-shifted section that causes a torsion axis of the apparatus to pass through the head. In yet another implementation, the presently disclosed technology teaches a method for reducing baseplate resonance amplitude. The method includes shifting a baseplate mass on a suspension toward an adjacent disc surface to move a baseplate torsion axis to pass near a head.

Abstract translation: 在一个实施方式中，本公开的技术教导了具有附接到基板的端部的头部的装置。 底板包括一个倾斜部分，该部分使底板的扭转轴通过头部附近。 在另一个实施方案中，本公开的技术教导了一种具有连接到基板的负载梁的装置。 该装置还包括附接到负载梁与底板相对的端部的头部。 底板包括使装置的扭转轴线穿过头部的质量偏移部分。 在又一实施方案中，本公开的技术教导了一种减少基板共振振幅的方法。 该方法包括将悬架上的基板质量移向相邻的盘表面以移动底板扭转轴线以靠近头部。
