Optical recording medium and apparatus for reproducing optical recording medium

摘要

An optical recording medium having plural recording layers includes a first recording layer on which first data is to be recorded and a second recording layer on which second data is to be recorded. The first and second recording layers are layered, with the second data being recorded at a location in the second recording layer in the vicinity of a location in the first recording layer where the first data relevant to the second data is recorded. Replay signals of variable configurations can be obtained by suitably synthesizing data read out from the respective recording layers.
