比特误差率

The method controls the move of head flying over the disk by firmware and analyzes the width change of projection of the read head, write head and erase band. The experiment shows skew angel can change off-track capability of magnetic head and change the radial error propagation of radial error of self servo-writing.

分离式磁头对硬盘驱动器伺服信息自刻写的影响同样不容忽视，为此提出了一种测定磁头偏移磁道能力大小的方法：通过控制磁头飞行过程，并在飞行过程中动态获取读头信号幅度和比特误差率，从而获取磁头磁道偏移能力。
