The main housing includes a window disposed on a front side of the housing allowing usable access to a front surface of a device disposed in the housing. In this connection, the controller and the expander transfers a set of transfer data in a plurality of the HDD-side physical links. When the held-in-hand detection mechanism detects that the equipment is not held in a person’s hand, the retraction mechanism causes the magnetic head 5 to be retracted from the recorded data portion of the magnetic disk 3 to the outside, so as to protect the magnetic disk device 1 and the data recorded on the magnetic disk from shocks. As the cable from the gear shifter is moved, the linkage element is rotated and that movement is transferred to the cable for the derailleur in a compensated manner.
