ABSTRACT:
An apparatus for positioning a magnetic transducer member with respect to a magnetic disk has an actuator which is rotated about an axis and includes an arm having a first end secured to the actuator for rotation of the arm about the axis. The arm has an oppositely disposed second end. A load spring member has a first end and a second end and is secured at its first end to the second end of the arm. A gimbal spring is secured to the second end of the load spring member and supports the transducer member. The gimbal spring permits the transducer member to move vertically and to pitch and roll as it flies over the rotating surface of the magnetic disk. The arm, load spring member, and gimbal spring are symmetrical with respect to a straight line running from the axis of rotation of the actuator to the center of the transducer. The transducer member is a two ski head and has a magnetic read/write core secured to the trailing edge of one of the skis. The center line of the core gap is substantially parallel to the trailing edge of the ski.
