Head arm assembly and disk drive device with the head arm assembly

A disk drive device including at least one head arm assembly that comprises:

• a head slider having at least one head element;
• an arm member for supporting the head slider at one end section;
• an actuator, mounted to the other end section of the arm member, for rotationally moving the arm member in a direction substantially parallel with a recording medium surface around a horizontal rotation axis of the arm member;
• a load generation means for generating a load for energizing said head slider in a direction to the recording medium surface by rotationally moving said arm member in a direction substantially orthogonal to said recording medium surface around a vertical rotation axis;
• and
• a limiter means for restraining said arm member from rotationally moving more than a predetermined limit in a direction to separate from said recording medium surface around said vertical rotation axis.
