用リニアアクチユエータ。 A linear actuator for a storage device linearly drives a carriage equipped with a transducer for a storage device that reads information from a magnetic disk, and positions the transducer at a desired position, the linear actuator supporting the carriage, and One leg includes a guide means for guiding linear motion, a pair of drive coils connected on both left and right sides in a direction perpendicular to the moving direction of the carriage, and a center magnetic pole fitted into each drive coil. It is equipped with a U-shaped outer box yoke, and a yoke cap that is fixed to both legs of the outer box yoke and forms a square-shaped magnetic circuit with the outer box yoke, and the left and right drive coils are connected to a square-shaped magnetic circuit. A magnetic circuit assembly configured by the yoke and the yoke cap, which is set in an intersecting relationship with the yoke and is disposed inside the outer box yoke, facing the center magnetic pole.
A linear actuator for a storage device, characterized in that it is provided with a number of permanent magnets.
