ABSTRACT:
There is disclosed an information storage apparatus in which even when a remaining power of a battery or a galvanic cell is low, an information recording medium can safely be removed. An MPU, a spindle motor driver, and a spindle motor constitute a decelerator for decelerating rotation of the information recording medium, and as a deceleration mode, a first deceleration mode with a relatively large power consumption and a second deceleration mode with a relatively small power consumption are used. The MPU monitors a voltage of a power supply line via a DSP, decelerates the rotation of the information recording medium in the first deceleration mode when the voltage exceeds a predetermined level, and decelerates the rotation of the information recording medium in the second deceleration mode when the voltage indicates the predetermined level or less.
