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.
