The invention relates to magnetic recording devices and a method for unsticking a head/slider assembly stuck on the surface of a magnetic recording disk. The method includes a first step which determines a resonant frequency of a mechanical system containing a magnetic recording disk, a head/slider assembly and a flexible support arm in which the resonant frequency of the mechanical system varies depending upon a position of the head/slider assembly on the surface of the magnetic recording disk, and a second step which oscillates the spindle motor and/or the voice coil motor at the resonant frequency to unstick the head/slider assembly from the surface of the magnetic recording disk.
