摘要： Approaches for a fluid dynamic bearing (FDB) system for use within a hard-disk drive. A fluid dynamic bearing (FDB) system may comprise an upper conical bearing and a lower conical bearing that are both disposed along a stationary shaft on which a magnetic-recording disk is rotatably mounted. The upper conical bearing and the lower conical bearing may have different cone angles, diameters, and/or lubricants to produce a desired difference in stiffness between the first conical bearing and the second conical bearing. By adjusting characteristics of the fluid dynamic bearing (FDB) system to achieve the desired bearing stiffness ratio, the tendency for the magnetic-recording disks to experience a sustained vibration when the hard-disk drive receives a mechanical shock is reduced. By preventing the magnetic-recording disks from sustained vibration after a mechanical shock, data may be written to and read from the magnetic-recording disks with greater reliability.
摘要翻译：用于在硬盘驱动器内使用的流体动力轴承（FDB）系统的方法。流体动力轴承（FDB）系统可以包括沿着固定轴设置的上锥形轴承和下锥形轴承，磁盘记录盘可旋转地安装在固定轴上。上锥形轴承和下锥形轴承可以具有不同的锥角，直径和/或润滑剂，以在第一锥形轴承和第二锥形轴承之间产生期望的刚度差。通过调整流体动态轴承（FDB）系统的特性以达到所需的轴承刚度比，减小了磁盘驱动器受到机械冲击时持续振动的趋势。通过防止磁记录盘在机械冲击之后的持续振动，可以以更高的可靠性将数据写入磁记录盘并从其中读出。

摘要： Apparatus and methods are disclosed that regulate head fly height so as to compensate for variation in height of a disk surface. An exemplary apparatus includes a circuit that detects disk height variation in response to variation in the gain of a variable gain amplifier, within an automatic gain control loop, that amplifies a read signal as the head reads from the disk surface. The circuit regulates the head fly height so as to compensate for the detected variation in disk height.

摘要： A first joint member connects the surface of a support body to a first end surface of a head slider. A second joint member connects the surface of the support body to a second end surface of the head slider. The first and second end surfaces respectively stand upright from the surface of the support body at opposite ends of the head slider. The centroid of a first joint surface established between the first joint member and the first end surface is located in a range between the front surface of the head slider and the neutral plane. The neutral plane is established when the head slider is deformed to convex or concave the front surface. When temperature changes, the bending deformation of the medium-opposed surface is reduced. This results in prevention of a change in the flying height of the head slider.

摘要： A linear tape system has a multi-reproducing head MRh comprising a plurality of reproducing heads Rh each of which corresponds to one recording track Tr. Each reproducing head of the multi-reproducing head is arranged with a displacement in a width direction of the recording track. An entire width MRhw of the multi-reproducing head is enlarged larger than a width Trw of the recording track. In this manner, the linear tape system can reproduce the recording track recorded in a narrow width and provide a higher recording density.

摘要： A bond pad is elevated from a slider body by a conductive post. The bond pad is disposed atop the post, which typically possesses a cross-sectional area smaller than the surface are of the bond pad. Thus, rather than having the entire surface of the bond pad in contact with the slider body, only the cross-sectional area of the conductive post is in contact therewith. Alternatively, a bond pad may be split into two electrically coupled pads: one pad used for housing a permanent bond, and a second pad used for housing a temporary bond. The pad used to house the temporary wire bond may be disposed atop a sacrificial layer. After a lapping process, the sacrificial layer may be etched away, thereby permitting the temporary pad to be removed.

摘要： An aerodynamic slider has at least one side surface that is continuously curved between the leading and trailing surfaces to substantially eliminate off-track forces on the side surface due to changing skew orientations. A slider profile is modeled, and a numerical simulation of airflow on the modeled profile is generated for each of a plurality of skew orientations within a range of skew orientations at which the slider will fly. The modeled slider profile is repeatedly adjusted based on the numerical simulations until a vibration analysis on the modeled profile indicates vibration does not exceed a predetermined minimum.
