摘要： A head disk assembly file has a tub-type basecasting with side walls, a floor and a pack of hard disks. The file also comprises an actuator having a set of head gimbal assemblies with magnetic heads. The actuator is secured to the file and is rotatable from a pre-merge position outside of the disks to an inner diameter position near the centers of the disks. A head merge tool comprising a merge comb with fingers interfaces with the file at a home position. In the home position, the merge comb is surrounded by but free of contact with the side walls, the floor and the head gimbal assemblies. The floor has a recess located beneath the merge comb. The recess extends from one side wall to the inner diameter of the disks and provides a clearance for a lowermost finger of the merge comb. A flexible cable extends from the actuator to the floor. A depression in the floor adjacent to the recess accommodates the flexible cable. The depression is located beneath the path of and free of contact with the merge comb and actuator. During assembly, the merge comb is placed in the file at the home position and rotated so that the fingers engage and move the head gimbal assemblies to merge the heads. The lowermost finger moves beneath the lowermost disk in the recess free of contact with the lowermost disk and a floor surface of the recess. The merge comb then returns to the home position and disengages the file.

摘要翻译： 头盘组件文件具有带有侧壁，地板和一堆硬盘的盆式底座。 该文件还包括具有一组具有磁头的磁头万向架组件的致动器。 致动器被固定到文件并且可以从盘外部的预合并位置旋转到靠近盘的中心的内径位置。 一种头部合并工具，其包括具有手指的合并梳子，该文件与原始位置处的文件接合。 在起始位置，合并梳被四周围绕，但不与侧壁，地板和头部万向节组件接触。 地板在合并梳下面有一个凹槽。 凹部从一个侧壁延伸到盘的内径，并为合并梳的最下部手指提供间隙。 柔性电缆从致动器延伸到地板。 靠近凹槽的地板上的凹陷容纳柔性电缆。 凹陷位于与合并梳和致动器的路径下方并且不接触的位置。 在组装期间，合并梳被放置在原始位置的文件中并旋转，使得手指接合并移动头部万向节组件以合并头部。 最下面的手指在凹槽中的最下面的盘下方移动，与最下面的盘和凹槽的地板表面接触。 合并梳然后返回到原始位置并脱离文件。
