Abstract: 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.
