An actuator for linearly moving magnetic heads (22) in which an open-ended carriage (10) assembly extends down both sides of the magnet structure (12) in order to provide a much shorter actuator assembly than is typical. The loading mechanism (14, 16, 52, 62) is not mounted upon the carriage assembly (10), thereby allowing the actuator to have a higher resonant frequency than those actuators which carry a more complex structure on the carriage assembly (10). The magnet structure (12) is in the shape of an E with the motor coil (24), which is mounted across the open end of the carriage assembly, moving along this center section (18) of the magnet structure (12). Alignment pins (64) located at the other end of the carriage asembly allow the magnetic head arms (66, 68) to be mounted and aligned quickly and with precision. |
