Patent ID: 7474486

Claim:
A magnetic storage media, comprising: at least one magnetic polarity encoded servo band having a width; and wherein each magnetic polarity encoded servo band includes: at least one magnetic south-north servo band section, each magnetic south-north servo band section including a magnetic south-pole polarity initialized servo track segment across all the width, and a magnetic north-pole polarity servo pattern recorded on the magnetic south-pole polarity initialized servo track segment; at least one magnetic north-south servo band section, each magnetic north-south servo band section including a magnetic north-pole polarity initialized servo track segment across all the width, and a magnetic south-pole polarity servo pattern recorded on the magnetic north-pole polarity initialized servo track segment; and wherein the at least one magnetic south-north servo band section and the at least one magnetic north-south servo band section are recorded relative to each other on a servo track to represent magnetic polarity encoded servo position information based on each magnetic north-pole polarity servo pattern and each magnetic south-pole polarity servo pattern.
