摘要： A recording medium includes a substrate, and a recording layer formed on the substrate having (a) a recording track band, and (b) recording cells regularly arrayed in the recording track band to form a plurality rows of sub-tracks. The recording cells included in each sub-track are formed apart from each other at a pitch P in the track direction. Nearest neighboring two recording cells, each positioned on adjacent two sub-tracks in the track band, are formed apart from each other at a pitch P/n in the track direction, where 2≦n≦5.

摘要： A recording medium has a substrate and a recording layer having isolation regions including crossed linear regions and substantially polygonal sections defined by the crossed linear regions, each of the sections containing particles of a recording material arrayed in a regular lattice. The linear regions of the isolation regions are formed along lowest-indexed planes of the regular lattice formed by the particles of the recording material.
