摘要：
A magnetic storage media has a servo track segment and a timing based servo band recorded on the servo track segment. The timing based servo band includes a modulated timing based servo pattern string representative of magnetic encoded servo position information for facilitating a determination of a servo position error signal. Exemplary forms of the modulation of the timing based servo pattern string includes a pattern interspacing modulation, a magnetic intensity modulation, and a pulse position modulation.
