Abstract: An integrated spring head/gimbal assembly holder is used to precisely load and unload a head/gimbal assembly (HGA) of the type used in magnetic disk drives. The holder includes a fixture base by which the holder is mounted. A first boss extending from the fixture base has a surface in which a recess is formed. The recess receives a second boss on the end of the HGA so that HGA rests on the surface of the first boss. A cantilevered beam extends from the fixture base and serves as a spring which includes a clamping head. Flexure of the cantilevered beam forces the clamping head to drive the second boss firmly against the sidewalls at the edge of the recess and to force the HGA against the surface of the boss. Thus, the HGA is precisely positioned and secured to the holder.

Abstract: A hard disk drive flying height tester loader (10) which moves a head gimbal assembly (HGA) (12) about the pivot axis (PA) of the HGA. The HGA is mounted to a clamp (26) that is attached to a pivot arm (4O). The pivot arm is attached to a cam follower (52) which follows a cam (12). The cam is moved by a motor (64) that is attached to a stationary sideplate (42). Movement of the cam rotates the pivot arm, clamp and HGA between a first position and a second position. The pivot arm is coupled to the stationary sideplate by a ball bearing assembly (44) which has a radius of curvature (r). The center of the ball bearing radius intersects the pivot axis of the HGA so that the clamp and HGA rotate about the pivot axis when the motor and cam move the pivot arm between the first and second positions.

Abstract translation: 一个硬盘驱动器飞行高度测试器装载器（10），其围绕HGA的枢转轴线（PA）移动头部万向节组件（HGA）（12）。 HGA安装到附接到枢转臂（40）的夹具（26）上。 枢转臂附接到跟随凸轮（12）的凸轮从动件（52）。 凸轮通过附接到固定侧板（42）的电机（64）移动。 凸轮的运动使枢转臂，夹具和HGA在第一位置和第二位置之间旋转。 枢转臂通过具有曲率半径（r）的滚珠轴承组件（44）联接到固定侧板上。 球轴承半径的中心与HGA的枢转轴线相交，使得当马达和凸轮在第一和第二位置之间移动枢转臂时，夹具和HGA围绕枢转轴线旋转。
