A positioner () for a disk drive () that includes a magnet assembly (), a conductor assembly (), and a control system () is provided herein. The magnet assembly () includes a pair of magnet arrays (A) (B) and a pair of spaced apart flux return plates (A) (B). The conductor assembly () includes at least a first coil array () and a second coil array () that are substantially co-planar. The control system () directs current to electrically excite the coil arrays () () to maintain a data transducer () on a target track () of a storage disk ().

Positioner for precisely moving an e-block of a disk drive

A disk storage system having a mechanism for minimizing effects of slip/stick in a disk drive head assembly. A transducer is used to read data from and write data to a rotating disk. An actuator assembly holds the transducer. The actuator assembly is comprised of a load member onto which a flexure is attached. A slider is mounted onto the flexure. The transducer is mounted onto the slider. In this manner, the transducer can pitch and roll to maintain a constant height in reference to the disk's surface. A servo mechanism controls the acceleration and deceleration of the head according to a predetermined seek profile specifying how the transducer is to be moved for a particular seek. As the transducer approaches the destination track, the profile calls for a sudden deceleration surge in order to compensate for misalignments occurring during the seek due to the flexure slipping laterally in reference to the load member and sticking in that position because of friction.
