An E-block (20) and head stack assembly (15) for maintaining one or more data transducers (18) proximate one or more rotating storage disks (28) of a disk drive (10) is provided herein. The E-block (20) includes an actuator hub (52) and one or more actuator arms (22). The actuator arms (22) cantilever away from the actuator hub (52) and hold the data transducers (18) proximate the rotating storage disks (28). As provided herein, at least one of the actuator arms (22) has a roll-bias angle (70) over the majority of the length of the actuator arm (22). Moreover, the head stack assembly (15) maintains a suspension assembly (24) at a reduced suspension z-height (72) relative to the storage disk (28). As provided herein, the roll-bias angle (70) of the actuator arms (22) and the reduced suspension z-height (72), each decrease track misregistration.
