Abstract:
1. A recording control device, comprising: a recording control section which controls data recording on a recording medium having a plurality of recording layers, by irradiating laser light to the recording medium, wherein the recording medium comprises a number of sequential recording ranges for different recording purposes on each of the plurality of recording layers; and a division section which divides one of the sequential recording ranges of a prescribed recording layer, near a boundary of two mutually adjacent sequential recording ranges of another recording layer, wherein the other recording layer is disposed on a back side of the prescribed recording layer when viewed from a laser incident surface of the recording medium, wherein when data is not recorded to an area of one of the two mutually adjacent sequential recording ranges, a division position is set in the prescribed recording layer, separated by a prescribed distance from a position identical to a position of the boundary, in a direction connecting a center and an outer periphery of the recording medium, wherein the division section determines a buffer amount based on the position of the boundary in a radial direction, and sets the division position in the prescribed recording layer separated by the buffer amount, from the position identical to the position of the boundary in the prescribed recording layer.
