摘要：
A magnetic storage media includes a magnetic first-pole polarity initialized servo track segment and a magnetic second-pole polarity differential timing based servo pattern recorded on the magnetic first-pole polarity initialized servo track segment. The magnetic second-pole polarity differential timing based servo pattern represents magnetic encoded servo position information for facilitating a determination of a servo position error signal exclusive of noise.
