1. An information processing apparatus, comprising:

  • a hard disk drive that has a protective function for moving a head from a recording area of a disk to an evacuation position;

    at least one sensor configured todetect accelerations in triaxial directions orthogonal to one another,judge, out of biaxial directions among the triaxial directions, an axial direction closest to a direction vertical to the gravity direction by comparing a first angle formed between a first direction and the gravity direction with a second angle formed between a second direction and the gravity direction, anddetect, as a detection target acceleration, accelerations in one of a vertical direction with respect to a gravity direction and the judged axial direction; and

    circuitry configured to detect a movement of the information processing apparatus based on the acceleration detected as the detection target acceleration and determine whether to activate the protective function of the hard disk drive based on the detected movement.
