Magnetic-polarity encoded servo position information for magnetic-based storage media

摘要

A magnetic storage media includes a magnetic south-north servo band section and a magnetic north-south servo band section. The 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. The 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 and the 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 the magnetic north-pole polarity servo pattern and the magnetic south-pole polarity servo pattern.
