<p>An optical recording medium for recording lands/grooves by DWDD (Domain Wall Displacement Detection), wherein the depth d (nm) of a groove (3) in a magneto-optical recording medium is selected as 3μ/8n < d < 1μ/2n ... (1) or 1μ/2n < d < 3μ/4n ... (2) so as to balance land characteristics with groove characteristics.</p> |
