Abstract
A disk drive head stack assembly has a flexible printed circuit (FPC) including a flex cable and a flex stiffener. The flex stiffener includes a terminal region support portion that is attached to the actuator body, a flex cable guide portion, and a stiffener bend. The stiffener bend is between and connects the terminal region support portion and the flex cable guide portion. The flex cable includes a guided portion that is in contact with the flex cable guide portion. A flex cable terminal region is attached to the terminal region support portion. The stiffener bend is about a stiffener bend axis that is perpendicular to the actuator pivot axis.
