摘要： A linear voice coil actuator is disclosed which includes field subassemblies each including a field blank, and in which at least a one of the field subassemblies includes magnets of alternating polarity positioned on the field blank to form interleaved-magnetic circuits in a direction of motion of the linear voice coil actuator. The field subassemblies are positioned with respect to one another to form a gap between the field subassembly having the magnets, and another of the field subassemblies. Also included is a coil assembly that includes coils positioned in a plane within the gap, wherein the plane is substantially parallel to the direction of motion of the linear voice coil actuator. The field blanks include flux path sections which provide a flux path perpendicular to the direction of motion for each pair of magnets of opposite polarity that are separated by the gap, and which thereby results in the height of the actuator of the present invention being largely independent of the lengths of the magnets employed.

摘要： A coil construction for a voice coil motor is disclosed. The coil construction includes a series of stacked planar coils disposed on a substrate material. Each planar coil is separated from its neighboring coil or coils by a viscoelastic material to reduce vibration of the coil construction. The coil construction is attached to an actuator arm. Control circuitry creates a current in the coil construction to position a head on the actuator arm. Also disclosed is a method for making a coil for a voice coil motor. The method includes the steps of masking a substrate having a conductive layer with a photoresist, exposing the mask to create a pattern of planar coils, developing the photoresist, and etching the conductive layer to create a planar coil.
