Zusammenfassung:	PURPOSE:To improve the reliability of the operation of a magnetic disk device by preventing the occurrence of thesmal off-track. CONSTITUTION:Plural magnetic disks 8 and first spacers, which are alternately arranged in the outer peripheral part of a spindle hub 3 in the direction of an axis, are pressure-sandwiched and fixed between a flange part 3a provided for one end of the spindle hub 3, and a clamp 9 arranged at the other end. A second spacer 6 in which a section consisting of a flange 6a and a web 6b has a protruding form and whose rigidity for shearing force in e direction of a diameter is smaller than the first spacer 7 is laid between the flange part 3a of the spindle hub 3 and a data disk 8b positioned at the arrangement end of the side of the flange part 3a concerned.
