Abstract:
A magnetic storage system, comprising:a disk with a concentric data surface of data tracks;a spindle shaft supporting said disk, said spindle shaft for rotating said disk about an axis generally perpendicular to the disk;a slider maintained in operative relationship with the data surface when the disk is rotating;a transducer attached to the slider for reading data from and writing data to the data surface;an electronics module for processing data read from and written to the data surface;a first and second current supply for providing electrical power; andan actuator for moving the slider generally radially relative to the disk to allow the transducer to access the data tracks, the actuator further comprising a body defining the actuator pivot point; a first coil support arm extending from the body; a second coil support arm extending from the body, said first and second coil support arms forming an angular sector therebetween; an outer actuator coil connected to the first current supply and affixed to the first and second coil support arms in the angular sector between said first and second coil support arms; and an inner actuator coil connected to the second current supply and affixed to the outer actuator coil, said inner actuator coil lying inside and in the same plane as said outer actuator coil.
