An apparatus for preventing vibration of actuator in optical disk system having electromagnets mounted in regions opposed to a actuator coil to prevent the vibration of pick up; a switch control signal generated controlling the ON/OFF of the switch according to regeneration mode in feeding the pick up; and a voltage-current convertor converting to the current proportional to the voltage applied through the switch control signal generator to supply it to the electromagnets through a current amplifier is disclosed. Thereby, it is possible to reduce access time and to enhance performance.
