A positioner (20) for a disk drive (10) that includes a magnet
assembly
(52), a conductor assembly (54), and a control system (22)
is provided herein. The magnet assembly (52) includes a pair of magnet arrays
(56A) (56B) and a pair of spaced apart flux return plates (75A)
(75B). The conductor assembly (54) includes a coil array (78).
The coil array includes a first portion (84) and a second portion (86)
that are positioned substantially perpendicular to a longitudinal axis (43)
of an E-block (16). The control system (22) directs current to electrically
excite the first and second portions (84) (86) to generate a first
force F1 and a second force F2 which are (i) parallel to
the longitudinal axis (43) of the E-block (16), and (ii) equal in
magnitude and directionally opposite to better position a data transducer (50)
on a target track (32) of a storage disk (28).
