Pickup for accessing moving storage media and drive having the pickup

Abstract

A pickup (P) for accessing moving storage media (D) carrying substantially parallel information tracks (T) has a carrier (C), a movable actuator (A) with a lens and suspension means joining the carrier (C) and the actuator (A). The actuator (A) carries coils. The pickup (P) has a magnet configuration, which is connected to the carrier (C), with at least one multipolar magnet having two ore more poles. In a section of the multipolar magnet, which faces one of the coils, two opposing magnetic poles adjoin along a first separation line. The separation line has a first line part and a second line part, where the widths of corresponding pole parts of at least one of the adjoining magnetic poles differ. According to the invention at least one magnetically active element increasing or decreasing the magnetic flux is attached to the multipolar magnet at least one of the pole parts with different widths.
