PURPOSE:To inhibit the loading of a head outside a prescribed humidity range, by providing a humidity sensor at a prescribed position of the deck of a mechanism part to detect the relative humidity inside a magnetic disk storage device and using the detecting signal to control the loading of the head. CONSTITUTION:A magnetic disk storage device is provided with a deck 1 of mechanism part, a spindle 2, a magnetic disk 3, a magnetic head 4, a head arm 5, a dustproof cover 6, an actuator 7, a spindle motor 8, pulleys 9 and 10, a belt 11, a humidity sensor 12, a humidity detecting circuit 13, and a head loading control circuit 14 which uses the output of the circuit 13 as an input. The sensor 12 detects the relative humidity within the deck 1, and the circuit 13 delivers the voltage corresponding to the relative humidity. |
