Abstract
In a method for writing data to an information recording medium having a plurality of recording layers, user data is written across between a plurality of the recording layers, and data other than the user data is written in a predetermined zone of the recording layer. Thereby, since the user data is written continuously upon switching of a recording layer without data other than the user data being written, it is possible to avoid interruption of writing of the user data to the recording layers.
