PURPOSE: To perform the stable follow-up contact travel of a contact surface with respect to a recording medium surface by providing each element so that the wavy amplitude value of the recording medium surface satisfies a specific expression to reduce the spacing variation of a contact slider. CONSTITUTION: This magnetic memory device is provided with a magnetic head slider 1 on which a magnetic transducer is mounted and which performs follow-up contact travel with respect to a magnetic recording medium surface travelling at a circumferential speed Vm/s. When the length of a contact surface in the travelling direction of a contact part with the magnetic recording medium surface of the magnetic head slider 1 is bmm, the presser load of a magnetic head slider support body 2 for pressably supporting the magnetic head slider 1 is Fgf, the wavy wavelength of the magnetic recording medium surface is Lμm and the amplitude of waviness is uo nm, each element is formed so as to satisfy an expression [I], wherein (f) expresses the frequency of waviness (f=v/L).
