Abstract:
An optical disk (100) comprises recording management areas (103, 113) in which record management data for managing data recording is recorded. The record management data includes (i) physical position information (122, 125, 126) indicating the positions of physical buffer areas in which buffer data for buffering recording operation is physically recorded and (ii) logical position information (121) indicating the position of a logical buffer area in which buffer data is logically recorded or to be recorded.
