<P>PROBLEM TO BE SOLVED: To provide a recording and/or reproducing device capable of easily obtaining the horizontal and vertical position accuracy of a support base. <P>SOLUTION: The recording and/or reproducing device is provided with a supporting means 20 for supporting the support base 19 supporting a recording and reproducing means movably in the radial direction of a disk-shaped recording medium, and an impact driving means having a driving shaft 24 and an electromechanical conversion element 25 provided at one end of the driving shaft 24 and extending or contracting in the axial direction of the driving shaft 24 in accordance with a driving pulse and for making the electromechanical conversion element 25 extend or contract to move a movable part in the direction of the driving shaft 24. The movable part has a sliding and guiding part 32 where a horizontal surface part 32a crossing almost orthogonally with the moving direction of the support base 19 and a vertical surface part are formed and which slides on the driving shaft 24, and an elastic member 31a that presses the driving shaft 24 to the sliding and guiding part 32. <P>COPYRIGHT: (C)2003,JPO |
