摘要:
A magnetic storage media includes one or more magnetic polarity encoded servo bands with each magnetic polarity encoded servo band including one or more magnetic south-north servo band sections and one or more magnetic north-south servo band sections. Each magnetic south-north servo band section includes a magnetic south-pole polarity initialized servo track segment and a magnetic north-pole polarity servo pattern recorded on the magnetic south-pole polarity initialized servo track segment. Each magnetic north-south servo band section includes a magnetic north-pole polarity initialized servo track segment, and a magnetic south-pole polarity servo pattern recorded on the magnetic north-pole polarity initialized servo track segment. The magnetic south-north servo band section(s) and the magnetic north-south servo band section(s) are recorded relative to each other on a servo track to represent magnetic polarity encoded servo position information based on the magnetic north-pole polarity servo pattern(s) and the magnetic south-pole polarity servo pattern(s).
