An information processing apparatus which comprising a recording section for recording information in a removable recording medium, a switch, a computer, a power supply section for supplying power to the recording section and the computer, and an operating system which is software for controlling the computer. The power supply section controls power supply to the recording section and the computer individually and, only the power supply to the recording section is controlled ON/OFF corresponding to a state of the switch. The operating system conducts a processing based on a presumption that the recording section is not connected. Under the above-described configuration, when there is no access made to the recording section, the power supply is disconnected not only to the recording section but also to a constituent part used for making access to the recording section. Thus the advantage of low-power operation is further enhanced.
