<p>Disclosed is an optical recording medium having the smallest number of different interlayer distances that allows cancellation of the effect of interlayer crosstalk. Specifically disclosed is an optical recording medium comprising N recording layers (where N = 4) grouped into one or more AB blocks each consisting of 4 recording layers formed one above another, wherein there are M different interlayer distances, where M is the smallest integer equal to or larger than log2(N), and wherein in each AB block, the first and second recording layers are separated by a first interlayer distance (A), the second and third recording layers are separated by a second interlayer distance (B), and the third and fourth recording layers are separated by the first interlayer distance (A). Also specifically disclosed is an optical recording medium comprising an AB block and a recording layer, wherein there are M different interlayer distances, where M = 3, and wherein the recording layer and the adjacent recording layer of the AB block are separated by a third interlayer distance (C).</p> |
