Abstract
A magnetic head supporting mechanism supports first and second magnetic heads in relation to a flexible magnetic disk in a manner such that the heads move in a generally perpendicular direction to the plane of the flexible disk. The motion of the heads is constrained by the spring rate of the supporting plates in the generally perpendicular direction to the plane of the flexible disk and the warping of the plates is further constrained by the torsional rigidities of the plates. The spring rate and the torsional rigidities of the supporting plates are set within preferred ranges.
