PURPOSE:To prevent the deterioration in the reproducing state and generation of noise due to the radial feeding by allowing a magnetic head to slide a magnetic recording pat of a magnetic sheet while drawing a concentric tracking locus in most of the reproducing time. CONSTITUTION:A body 55 to be detected corresponding to a rotary detection sensor 66 is fixed to a turntable 12 and a drive motor 15 is controlled by a main control section 56, a feed motor 49 is controlled by a feed control section 57 and they are communicated by a 2-way signal transmission means 58. Thus, the magnetic head is moved along the concentric true circle, the recording content is reproduced from the magnetic recording section, the magnetic head is moved by a prescribed quantity in the radial direction to the center of the magnetic recording part so as to move the head from the outer tracking locus to the inner tracking locus obliquely, the head is slid while drawing a concentric circle on a new tracking locus and the content is reproduced.
