| 摘要 | An information processing apparatus includes a hard disk unit, a control unit configured to output an instruction to retract a head of the hard disk unit, a monitoring unit configured to monitor a state of the control unit and output, in a case where the monitoring unit determines that the control unit cannot issue the instruction, an instruction to retract the head of the hard disk unit, and a hard disk controller configured to receive the instruction from the control unit or the monitoring unit and to issue a command for retracting the head of the hard disk unit to the hard disk unit. The hard disk unit retracts the head of the hard disk unit in a case where the hard disk unit receives the command. | ||

| 主权项 | 1. An information processing apparatus comprising: a hard disk unit; a control unit configured to output an instruction to retract a head of the hard disk unit; a monitoring unit configured to monitor a state of the control unit and output, in a case where the monitoring unit determines that the control unit is in a state where the instruction to retract the head of the hard disk unit cannot be output, an instruction to retract the head of the hard disk unit; and a hard disk controller configured to receive the instruction from the control unit or the monitoring unit and to issue a command for retracting the head of the hard disk unit to the hard disk unit in a case where the hard disk controller receives the instruction from the control unit or the monitoring unit, wherein the hard disk unit retracts the head of the hard disk unit in a case where the hard disk unit receives the command. | ||
