ABSTRACT:
A method, system, apparatus, and computer readable medium storing instructions for recording data tracks and a method and system for reading data tracks. For recording data tracks, virtual boundary of a first data track recorded on the storage medium is determined. The recording element is positioned based on the determined virtual boundary of the first track and a second data track is recorded by the positioned recording element. For reading data tracks, a first virtual boundary of a first data track and a second virtual boundary of the first data track are determined and a reading element is positioned at a center of the first data track based on the determined virtual boundaries. In the system of reading recorded data tracks, a number of forward reading elements and backward reading elements are provided. The forward reading elements have different pitches.
