摘要：

We devised a dc-free servo pattern for perpendicular recording to prevent distortion of the readback wave form from the servo area. This servo pattern remarkably improves the servo sector error rate, and shows the same linearity of position error signals as does that from a conventional pattern. An experimental 2.5 in hard disk drive (HDD) with a trapezoidal-shaped single pole type (SPT) head shows good following performance within a wide range of yaw angle.
