A head positioning mechanism for a magnetic disc device includes a support spring having one end portion that supports a magnetic head, and the other end portion at which a rotating shaft is disposed. A carriage has one end portion that pivotally supports the rotating shaft of the support spring, and another end portion that is connected to a rotary actuator, to position the magnetic head to a predetermined position on the magnetic disc in cooperation with the carriage and the support spring. A stopper is provided on the carriage, and restricts a rotatable range of the support spring on the carriage. A positioning control at a head precision seek is facilitated as a result.
