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 is comprised of a load member onto which a flexure is attached. A slider is mounted onto the flexure. 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 (602) specifying how the transducer is moved for a particular seek. As the transducer approaches the destination track, the profile (602) calls for a sudden deceleration surge (603) in order to compensate for misalignments ocurring during the seek due to the flexure slipping laterally in reference to the load member and sticking in that position because of friction. |
