摘要： Disk spacers in multiple disk drives are shaped to provide a reliable mechanism for loading and unloading magnetic recording heads and a reliable latch when the heads are unloaded. The head load/unload system operates between a stack of latch-profiled spacer ramps sandwiching magnetic hard disks and a stack of lifting arms with contoured tips attached to head/suspension assemblies. The lifting arms and their contoured tips are built as part of the one-piece of the suspension load beams at their inner diameter side perpendicular to the load beam axis, or at their front along the axis. The spacer ramps are precisely machined to a latch profile with a desired rounded edge merging with the disk surface, an inclined slope, a round hump and a rounded recess, so that the contoured tip of a lifting arm can slide onto the slope first, over the hump and then into the recess where the tip is latched. The spacer ramps also serve either in a couple as the separator of any two adjacent disks, or individually as the separator between the top disk clamp and the top surface of the top disk and between the bottom base and the bottom disk. The spacer ramps are self-calibrated vertically with the disk stack. Both coated with diamond like carbon or other hard coatings, the profiled spacer ramps, also coated with lubricants after a hard coating, and contoured tips are reliable in ramp wear control. A single sided limiter from the suspension load beam reduces the torsion to the head flexure tang generated by the lifting force at an inner side lifting arm when the head is unloaded from the disk.

摘要翻译： 多个磁盘驱动器中的磁盘间隔件成形为提供用于装载和卸载磁记录头的可靠机构以及当卸载磁头时可靠的闩锁。 头部装载/卸载系统在夹住磁性硬盘的闩锁型间隔斜坡的堆叠和附接到头部/悬挂组件的轮廓的提升臂之间进行操作。 提升臂及其轮廓的尖端被构建为垂直于负载梁轴线的内径侧的一个悬挂载荷梁的一部分，或者沿其轴线的前端。 间隔件斜面被精加工成具有与盘表面，倾斜斜面，圆形隆起和圆形凹部合并的所需圆形边缘的闩锁轮廓，使得提升臂的轮廓顶端可以先滑动到斜坡上 驼峰然后进入尖端被锁定的凹处。 间隔斜面还可以作为任何两个相邻盘的分离器，或单独地作为顶盘夹具和顶盘的顶表面之间以及底部底部和底盘之间的分离器。 间隔斜坡与磁盘堆叠垂直自校准。 两者均涂覆有类似于金刚石的碳或其他硬质涂层，成型间隔板斜面，在硬涂层之后也涂有润滑剂，并且轮廓尖端在斜面磨损控制中是可靠的。 来自悬挂载荷梁的单侧限制器在头部从盘上卸载时，减小由内侧提升臂处的提升力产生的头部弯曲柄部的扭转。

摘要： Disclosed is a magnetic storage cartridge adapted to be removably received by a drive base. The magnetic storage cartridge comprises a housing that includes at least one magnetic disk rotatable about an axis, and an actuator arrangement pivotal about an axis. The actuator arrangement includes at least one read/write head for reading and writing information to and from the at least one magnetic disk. The housing also includes a first engagement feature positioned on the housing at the rotational axis of the magnetic disk and a second engagement feature positioned on the housing at the pivot axis of the actuator arrangement. The housing of the storage cartridge also includes a third engagement feature that is spaced from the first and second engagement features. The first, second and third engagement features adapted to be engaged by a corresponding first, second and third engagement features of the disk drive base to secure the magnetic storage cartridge to the disk drive base and substantially minimize performance degrading vibrations during operation of the magnetic storage cartridge.

摘要： A magnetic recording disk coating having a high density of magnetic particles uniformly dispersed in a high performance, thermoset polyurethane resin binder with the dispersion applied as a thin coating onto a rigid substrate. The thermosetting resin binder comprises a blocked isocyanate polymer reacted with hydroxy terminated or branched oligomer or oligomers. The coating composition has an extended shelf life and can be cured at temperatures below 375.degree. F. to produce a smooth, hard, tough durable and well dispersed magnetic coating with an improved orientation ratio that readily accepts buffing, washing, and lubrication.
