ABSTRACT:
The improved disk drive system has an improved head gimbal assembly having a mounting plate with an attachment portion for attachment to an actuator arm and a distal end for mounting the read/write heads, or load beam assemblies, thereto. The mounting portion and distal end of the mounting plate are vertically offset such that when the attachment portion is attached to the actuator arm, the distal end of the mounting plate is centered between opposing sides of adjacent disks, thereby permitting a smaller spacing between adjacent disks. The new swage type connection between the mounting plate and the actuator arm has a hole in the actuator arm and has a spud located on the attachment portion of the mounting plate. The spud has a cylinder having an outer diameter such that the cylinder can fit inside the actuator arm hole. A distal end of the cylinder has a lip protruding inwardly from an inside diameter of the cylinder. The cylinder has a length such that when the cylinder is inserted into the actuator arm hole, the lip and the distal end of the cylinder extend beyond the thickness of the actuator arm around the actuator arm hole so that when the spud is swaged while in the actuator arm hole, the lip and the distal end of the cylinder expand into an area outside the actuator arm hole.
