摘要： A coil-embedded dust core and a method for manufacturing the coil-embedded dust core are provided. The coil-embedded dust core comprises a coil formed from a flat conductor wound in a coil configuration, and a green body consisting of insulating material-coated ferromagnetic metal particles. This results in a coil-embedded dust core more compact in size but with larger inductance. A rectangular wire can be used as the flat conductor. In addition, parts of the coil may function as terminal sections. In this case, the terminal sections of the coil may be formed wider than other part of the coil. The coil-embedded dust core is less prone to joint failures between a coil and terminal sections and to insulation failures of the coil and the terminal section with respect to the magnetic powder. The coil-embedded dust core is more compact while achieving larger inductance.

摘要： The invention provides a process for producing a coil-embedded dust core by embedding a coil in magnetic powders comprising ferromagnetic metal particles coated with an insulating material. At the first compression molding step one portion of magnetic powders is filled in a molding die and then compression molded to form a lower core. At a coil positioning step the coil is positioned on the upper surface of the lower core in the molding die. At a coil embedding step another portion of magnetic powders is again filled in the molding die in such a way that the coil is embedded in these magnetic powders. At the second compression molding step pressure is applied to the lower core and coil in the direction of lamination thereof.

The coil-embedded dust core includes a coil 1 formed by winding a flat conductor 2 and a green body 10 comprising of ferromagnetic metal powder coated with an insulating material. The coil 1 is composed of a winding section 3 in which the flat conductor 2 having front and back surfaces opposed to each other with a predetermined distance is wound and lead-out end sections 4a and 4b that are extended from the winding section 3. Either one of the front and back surfaces of the lead-out end section 4a and either one of the front and back surfaces of the lead-out end section 4b are formed so as to be on the same plane. By using the coil 1 in which the both end sections (lead-out end sections 4a and 4b) are formed on the same plane, the coil-embedded dust core can be made smaller in size, and high inductance can be provided.

摘要： A pickup for accessing moving storage media carrying substantially parallel information tracks has a carrier, an actuator with a lens and suspension wires extending from the rear of the carrier and joining the carrier and the actuator. The actuator is movable in the focus direction and in a tracking direction and has a substantially rectangular flat board carrying the lens and a counter weight. The flat board is arranged orthogonal to a focus direction and carries tracking and focus coils. The pickup has a magnet configuration connected to the carrier with at least two tracking magnets, which are arranged in the tracking direction at opposite sides of the flat board and extend orthogonal to the focus direction above and/or under the flat board, and with at least two focus magnets, which are arranged in front of and behind the flat board and extend orthogonal to the direction of the tracks. According to the invention, the lens is arranged asymmetrically in reference to an axis through a center of the flat board parallel to the direction of the tracks while the lens and the counter weight are symmetrically arranged in reference to the center of the flat board.
