Abstract: A voice coil actuator return path and a slotted flex circuit member for a linear actuator (70) of a disk drive (110). The outer return path (72) is formed from laminations of low carbon steel and supports and positions a central guide track (53) on which a carriage assembly (50) slides. The outer return path (72) is oriented in a rectangle that is coupled to a disk drive and includes an aperture (78) through which a portion of the carriage assembly passes. A flex circuit member (10), which electrically connects the read/write heads (52A and 52B), includes a slot (25) that enables the central guide track (53) to pass through, thereby enabling connection to the carriage assembly near a central axis (40) of the carriage (50). The flex circuit member (10) has a center of mass and center of force approximately equally distributed on each side of a vertical plane passing through a centerline of the central guide track.
