ABSTRACT:
A track accessing mechanism includes a track accessing arm actuable by a primary actuation device for accessing concentric data tracks on a storage medium and at least one slider attached to the track accessing arm. The at least one slider includes a servo head configured to read positional information from a plurality of continuous, concentric rings radially spaced apart from each other on a storage medium and a data head configured to read and write user data to the least one concentric data track. At least a portion of each ring includes servo information. The at least one data track is positioned between each continuous, concentric ring on the storage medium.
