PURPOSE:To reduce power consumption and to simplify adjustment during assembling, while realizing high-precision driving control over a recording head through extremely simple constitution, by employing a worm type moving device. CONSTITUTION:When a magnetic sheet 111 is loaded and a track number is specified by a tracking specifying circuit TR, a worm type moving device 101 is moved through a control circuit CN and a driving circuit DR to move the magnetic head 105 to the specified track. The magnetic head 105 is moved both forth and back according to the order of voltage application to parts 101a and 101c of the moving device 101. |
