のアクチユエータ機構。 In the actuator mechanism of a magnetic disk device, which accesses a desired position by reading position information written on the disk using a position reading head based on a command from a position control unit, one end of the actuator mechanism is connected to a voice coil motor. It consists of four parallel leaf spring type actuators driven by the guide rod, and the four parallel leaf spring type actuators are divided into two sets with a guide rod in between.
1. An actuator mechanism for a magnetic disk device, characterized in that sets of parallel leaf spring type actuators are arranged in parallel, and a leaf spring on one side of the leaf springs facing each other of the two sets of parallel leaf spring actuators is fixed.
