摘要：
This paper presents the repeatable runout (RRO) compensation in disk file systems. The applied repetitive controllers for the tracking system. As experimental results, we obtained a high reduction ratio of 10 similar to 45 dB for vp to 10th harmonics of the RRO. Furthermore, by switching filter parameters between in the learning state and the steady state, we obtained feast learning of less than two disk rotations.
