要約
(EN)

An information recording device can record a plurality of pieces of recording information, for instance, at different times, in an information recording medium provided by stacking first and second recording layers. A writing control element controls a writing element so that each piece of the information can be written over the first recording layer to the second recording layer. Furthermore, a boundary control member controls the writing element so that first boundary information is written in a recording area which is to be a boundary between the pieces of information in the first recording layer, and that second boundary information is written or ensured, in a recording area of a second recording layer which overlaps the recording area wherein the first boundary information of the first recording layer is written, as a recording area to be a boundary between the pieces of information in the second recording layer.
