PURPOSE:To improve the open loop characteristics by forming incorporatedly a carriage main body constituting part and a guide arm in a carriage structure and laminating and combining the incorporated object via a spacer at the carriage main body constituting part. CONSTITUTION:Guide arms 18, 20 where one guide arm and a carriage main body constituting part corresponding thereto are laminated at carriage main body constituting parts 19, 21 via a spacer 23 and clamped and incorporated by a clamping bolt 24. Then a carriage main body 25 incorporated with the guide arms 18, 20 is formed to the end of the guide arms 18, 20. The rigidity in the seek direction is increased in the carriage main body 25 formed in this way and the seek direction bending resonance generated in the real operating band (-several kHz) is increased to the outside of the real operating band, thereby improving the open loop characteristics. |
