Patent ID: 8363520

Claim:
An information processing apparatus for recording data into an optical disk including a plurality of recording layers in which to record data, by irradiating light thereto, said information processing apparatus comprising: forming means for forming, from a single piece of data to be recorded, element data constituting the single piece of data and reconstruction data for reconstructing the single piece of data in a case where the element data becomes unreadable; and recording position determining means for determining respective recording positions for the element data and the reconstruction data, which are formed by the forming means from the single piece of data, so that the element data and the reconstruction data are recorded at the respective recording positions in different recording layers, the recording position determining means determining the respective recording positions for the element data and the reconstruction data such that the respective recording positions do not overlap each other in a projection plane of the optical disk viewed in a light-irradiation direction in which the irradiated light travels.
