    摘要： A voice coil motor for use in a disk drive device suitable for causing rotation of a head gimbal assembly connected to a first end of the voice coil motor is provided. At least one protrusion may protrude from a second end of the voice coil motor, with the second end of the voice coil motor being opposed to the first end. The voice coil motor may be rotatable to move a head connected to the head gimbal assembly for a read and/or write operation and for parking. The protrusion may be disposed on the voice coil motor so as to cooperate with a single pin to define first and second maximum positions beyond which the voice coil motor cannot rotate. In certain example embodiments, the first maximum position may be a load position limit beyond which the voice coil motor cannot rotate during a read/write operation, and the second maximum position may be a park position limit beyond which the voice coil motor cannot rotate when the head is parked.
