Abstract: PURPOSE:To suppress the yawing and pitching of an optical head by minimizing sufficiently a spring constant to the displacement of a sixth or seventh rolling member and deflecting and fitting sufficiently the elastic body of a sheet spring shape between an optical head and a second guide shaft. CONSTITUTION:A sheet spring 12 is fitted by a screw 13 to a projecting part 2a of an optical head 2, and at both edges of the direction parallel to the central shaft of a second guide shaft 4, a holder part 12a of sixth and seventh rolling members 10 and 11 is formed. For the cross section shape of the sheet spring 12, the width of the direction of the rolling central shaft of the rolling members 10 and 11 is sufficiently wider than the width of the direction vertical to the rolling central shaft. Since a free edge and a fixed edge are sufficiently away for the sheet spring 12, the parts to accumulate the energy due to the elastic deformation are sufficient, and the spring constant to the displacement of the sixth rolling member 10 or the seventh rolling member 11 is sufficiently minimized. Thus, the yawing and pitching of the optical head 2 can be suppressed.
