A flexible disk device, in which a handle member is manually operated to move a holding asembly which either holds a flexible disk in an operating position or releases the disk, for removal. A cam selectively couples a pair of magnetic heads simultaneously to engage the disk and to hold them in position. The cam also decouples the heads from the disk. The cam may comprise first and second cam sections, which are reversibly rotatable on both sides of the disk when it is held in an operating position, respectively. In this event, it is preferred to make a head withdrawing assembly to forcibly rotate the cam to withdraw the heads from the coupled state whenever the handle member is actuated to release the disk. The head withdrawing assembly may comprise a protrusion attached to the cam and an arm attached to the handle member which do not engage each other to leave the cam freely and reversibly rotatable when the disk is held in position. The arm pushes the protrusion to forcibly rotate the cam whenever the handle member is actuated to release the disk.
