摘要： A seal is formed between bypass walls and a cover for a disk drive to improve control and regulation of airflow in the disk drive. The seal is formed with a gasket comprising a bead of form-in-place gasket between the upper edge of the bypass wall and the cover. The seal also may be formed between the cover and the slit shroud, spoiler, and filter. Minimum compression of the gasket is required to form the seal.

摘要： In a disk drive system transducer suspensions are swaged to the actuator arms. The end actuator arms in the arm stack experience unbalanced forces which detrimentally effect the flying height of the transducers. A compensating swage plate is swaged on the opposite surface of each of the end actuator arms such that these unbalanced forces are canceled and the transducer maintains the proper flying height.

摘要： The dynamics of a disk drive actuator are enhanced by redistributing the mass and stiffness of the structure. The two nodal points of the second primary bending mode of the actuator are relocated to positions that are both radially outboard of their original positions. One nodal point is positioned as close to the read-write head as possible at one end of the actuator, and the other nodal point is positioned at the center of the active legs of the VCM coil at the other end of the actuator. This is done to reduce the off-track displacement associated with this fundamental resonance to near zero, allowing higher track densities to be supported.
摘要翻译： 通过重新分配结构的质量和刚度，增强了磁盘驱动器致动器的动态性能。 致动器的第二主弯曲模式的两个节点被重新定位在其原始位置的径向外侧的位置。 一个节点位于致动器一端尽可能靠近读写头，另一个节点位于致动器另一端的VCM线圈的有效支脚的中心。 这是为了将与该基本共振相关联的偏离轨道位移减少到接近零，从而允许更高的轨道密度得到支持。
