Abstract: An information recording method of the present disclosure is an information recording method for recording information on a write-once information recording medium, including one or more recording layers, each of the recording layers being spiral-shaped on which a land track and a groove track are alternately repeated as recording tracks, each of the recording tracks being divided into blocks, each of the blocks being a minimum unit in which recording is performed. The information recording method includes: recording the information on the information recording medium in a unit of each of the blocks; and controlling recording on the information recording medium. In the control step, switching is performed whether to perform recording in a block to be recorded in which the information is to be recorded next among the blocks based on recording conditions of the recording tracks adjacent on both sides of the block to be recorded.

Abstract translation: 本公开的信息记录方法是一种信息记录方法，用于在包括一个或多个记录层的一次写入信息记录介质上记录信息，每个记录层是螺旋形的，在该记录层上，槽脊轨道和槽道 作为记录轨道交替地重复，每个记录轨道被分成块，每个块是进行记录的最小单位。 信息记录方法包括：以每个块为单位将信息记录在信息记录介质上; 并控制在信息记录介质上的记录。 在控制步骤中，根据要被记录的块的两面相邻的记录轨道的记录条件，执行切换是否在要记录的信息的块中进行记录。
