PROBLEM TO BE SOLVED: To provide a magnetic disk device having a large recording capacity wherein the magnetic head positioning accuracy is enhanced by increasing the rigidity of a carriage. SOLUTION: This magnetic disk device is provided with a magnetic head for reading/writing information on a magnetic disk, a carriage for supporting the magnetic head on the magnetic disk to move around a predetermined axis, and an annular coil supported by a bobbin disposed on the carriage to receive an electromagnetic force for driving the carriage. The device is further provided with a first joining member for joining the annular coil to the bobbin, a coil inner member arranged inside the annular coil, and a second joining member for joining the annular member to the coil. A modulus of elasticity of the coil inner member is larger than that of the first or second joining member.
