Disclosed is the method to reduce undesired oscillation after seek operation of a hard disk drive. To reduce the undesired oscillation the method was proposed which uses an symmetrical acceleration and deceleration profile. (US Pat. 5291110) According to it if the smooth deceleration profile which is required to reduce the undesired oscillation is used, the acceleration profile must be smooth. That means slower acceleration and
