Abstract
A disk drive system includes a base, a disk rotatably attached to the base, and an actuator assembly movably attached to the base. The actuator assembly moves the transducer to selected areas of the disk where information representative of data is to be written or read. The actuator assembly maintains the transducer in a transducing relationship with the disk. The actuator assembly also includes an arm which allows a suspension to be attached to materials other than metals, such as composite materials or ceramic materials. The arm is provided with a protruding attachment feature. In the preferred embodiment, two protruding attachment features are provided. The suspension includes at least one folding metal tab that is tightly folded around the attachment feature while the metal is at an elevated temperature. One metal tab is provided for each attachment feature on the arm. The elevated temperature used while the suspension is attached to the attachment feature is above the operating temperature of the drive. The resulting attachment forms a rigid compressional bond between the shrinking metal and unyielding arm material.
