Abstract
An information processing apparatus includes a hard disk drive, an acceleration detection portion, and a controller. The hard disk drive has a protective function for moving a head from a recording area of a disk to an evacuation position. The acceleration detection portion is configured to detect, as a detection target acceleration, an acceleration in one of a vertical direction and an almost-vertical direction with respect to a gravity direction. The controller is configured to detect a movement 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.
Claims14
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 to
- detect 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, and
- detect, 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.
A head evacuation processing method for an information processing apparatus having a built-in hard disk drive that has a protective function for moving a head from a recording area of a disk to an evacuation position, the head evacuation processing method comprising:
- detecting, at a least one sensor, accelerations in triaxial directions orthogonal to one another;
- judging, at the at least one sensor and 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, and
- detecting, as a detection target acceleration, accelerations in one of a vertical direction with respect to a gravity direction;
- detecting a movement of the information processing apparatus based on the acceleration detected as the detection target acceleration;
- and
- determining, via a processor, whether to activate the protective function of the hard disk drive based on the detected movement.
A non-transitory computer-readable medium storing computer readable instructions thereon which when executed by a computer cause the computer to perform a head evacuation processing method for an information processing apparatus having a built-in hard disk drive that has a protective function for moving a head from a recording area of a disk to an evacuation position, the head evacuation processing method comprising:
- detecting accelerations in triaxial directions orthogonal to one another;
- judging, 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, and
- detecting, as a detection target acceleration, accelerations in one of a vertical direction with respect to a gravity direction;
- detecting a movement of the information processing apparatus based on the acceleration detected as the detection target acceleration;
- and
- determining whether to activate the protective function of the hard disk drive based on the detected movement.
