Method for reducing noise during seeks in a hard disk drive

A method for moving a transducer head of a rotating disk data storage device from an initial data storage track on a rotating disk to a destination track on the disk, comprising the steps of:

• selecting a demand velocity fraction, less than one;
• for each of a first sequence of time intervals beginning with the transducer head located at the initial track, accelerating the transducer head toward the destination track by the steps of:
• determining the number of tracks between the transducer head and the destination track;
• selecting a profile velocity in relation to the number of tracks between the transducer head and the destination track;
• determining a demand velocity by incrementing a previous demand velocity by the selected fraction of the difference between the profile velocity and the previous demand velocity, wherein the previous demand velocity for the first time interval is selected to be zero and the previous demand velocity for each remaining time interval of the first sequence is the demand velocity for the previous time interval;
• measuring the actual velocity of the transducer head across the disk;
• and
• accelerating the transducer head in relation to the difference between the demand velocity and the actual velocity of the transducer head across the disk;
• and
• for each of a second sequence of time intervals subsequent to the first sequence, decelerating the transducer head to the destination track by the steps of:
• determining the number of tracks between the transducer head and the destination track;
• selecting a profile velocity in relation to the number of tracks between the transducer head and the destination track;
• measuring the actual velocity of the transducer head across the disk;
• and
• decelerating the transducer head in relation to the difference between the actual velocity of the transducer head across the disk and the profile velocity.
