Abstract
A magnetic disk drive with a head stack assembly includes a body portion, a main flex circuit, an actuator arm cantilevered from the body portion and a head gimbal assembly supported at the actuator arm. The actuator arm includes a proximal end and a distal end, a first side surface and a second side surface A first array of conductive traces is supported at the first side surface and a second array of conductive traces supported at the second side surface. Each conductive trace includes a proximal conductive pad proximate to the proximal end of the actuator arm, a distal conductive pad proximate to the distal end of the actuator arm and a conductive path between the proximal and distal conductive pads. The head gimbal assembly includes a load beam having a base region abutting the actuator arm, a head coupled to the load beam, first and a second array of base region conductive pads, each array of base region conductive pads positioned on the base region and for electrically connecting to the head. Distal solder structure electrically connects the first array of base region conductive pads to corresponding distal conductive pads of the first array of conductive traces and electrica…
