Abstract
An assembly and method for securing head suspension members on shelf segments of metallic or ceramic actuator arms in a disk drive. The assembly comprises an actuator arm with a reduced thickness shelf segment, at least one head suspension member, a staking member having particular attributes and a staking plate also having particular attributes. The assembly is designed such that forcible expansion of the staking member takes place exclusively within the material of the staking plate member. The method is formulated such that the constituent elements of the assembly are aligned, placed under compression and staked together wherein an interference fit is formed between the staking member and staking plate member and no forcible pressure from the staking procedure is transmitted to the actuator arm. The assembly and method are ideally utilized in a multi-disk disk drive in which a plurality of head suspensions are secured to multiple arms of a single actuator in a single procedure.
