A magnetic disk unit has a magnetic head-disk stickiness eliminating mechanism suitable for a small-sized, low power consumption type magnetic disk unit of a high recording density. The magnetic disk unit has a housing in which is enclosed a magnetic disk medium made of glass, a spindle and a spindle motor for driving the magnetic medium in rotation, a slider for supporting a magnetic head and an actuator for positioning the magnetic head. An impact force applying mechanism mounted adjacent the housing applies an impact force to the housing for manually imposing a predetermined certain impact force on the housing. By applying an impact force manually to the housing before use of the magnetic disk unit or when the disk unit becomes inoperative due to sticking, it is possible to easily eliminate the sticking phenomenon between the magnetic head and the magnetic disk medium, thus permitting operation of the magnetic disk unit.
