Appeal No. 2004-0723
Application No. 09/768,974
a coil array that couples to the E-block and is positioned
near the magnet assembly, the coil array being a generally
D-shaped loop including a first segment that is positioned
substantially perpendicular to the longitudinal axis of the
E-block, the first segment being adapted to interact with the
magnetic field to move the E-block relative to the storage disk.
13. A head stack assembly for moving a data transducer of a
disk drive relative to a target track of a storage disk, the head
stack assembly comprising:
an E-block having a longitudinal axis;
a transducer assembly secured to the E-block, the transducer
assembly including a data transducer;
a positioner including (i) a magnet assembly producing a
magnetic field, (ii) a coil array secured to the E-block and
positioned near the magnet assembly, the coil array being a
generally D-shaped loop including a first segment positioned
substantially perpendicular to the longitudinal axis, the first
segment including (i) a first portion, and (ii) a second portion;
and
a control system that directs current to the coil array to
move the data transducer relative to the target track.
35. The positioner of claim 23 wherein the magnetic arrays
extend a first distance parallel to a longitudinal axis of a head
stack assembly that includes the data transducer, the coil array
extends a second distance parallel to the longitudinal axis, and
the first distance is greater than the second distance.
The examiner relies upon the following reference in the
rejection of the appealed claims:

Appellant's claimed invention is directed to a positioner
for moving an E-block and a data transducer of a disk drive
relative to a storage disk. The positioner comprises a magnet
