ABSTRACT:
A track means defined by magnetic recording media on a substrate, the media along the track means having two levels, one for recording of data, and the other for recording of servo information, wherein recorded magnetic transitions at the second level define the servo information, the transitions arrayed along the track means as groups of converging lines which extend in crosswise or spanwise relation to multiple tracks. The data is recorded without any wasted magnetic space between tracks (zero guardband) using alternating angles (azimuthal) of magnetic orientation so that they do not interfere with each other when read. The read bead cores or gaps may be "oriented" to read recorded data transitions extending at different angles relative to track length direction.
