Abstract
A system and method for an improved magnetic head arm assembly (HAA) is disclosed. The HAA includes three principal components, a head gimbal assembly (HGA), a flexible printed circuit (FPC) assembly, and an actuator coil assembly. The design allows for HAA rigidity, yet each of the components is designable and manufacturable independent of one another, in addition to other advantages over current methods.
Claims33
A system for a magnetic head arm assembly (HAA) comprising:
- a head gimbal assembly (HGA) with an HGA mating portion;
- a flexible printed circuit (FPC) assembly with an FPC mating portion;
- and
- an actuator coil assembly with a first mating portion and a second mating portion;
- wherein
- each of said HGA, said FPC assembly, and said actuator coil assembly being manufactured independent of one another;
- said HGA mating portion is to be coupled to said actuator coil assembly first mating portion;
- and
- said FPC mating portion is to be coupled to said actuator coil assembly second mating portion.
