Information processing device, information recording medium, information processing method, and program

Abstract

The present invention achieves a configuration that prevents recording errors when data recording processing is performed on both the lands and the grooves of an optical disc. The present invention has a data processing unit that performs data recording processing control on both the lands and the grooves of an optical disc. When data is recorded onto a land or a groove, the data processing unit performs processing that detects a position at which the data recording states of both of the grooves or the lands that are adjacent to the land or the groove that is the data recording target coincide, or processing that makes the data recording states coincide. As processing that makes the data recording states of both of the grooves or the lands that are adjacent to the land or the groove that is the data recording target coincide, the data processing unit performs, for example, dummy data recording processing, skip processing, or the like.

Description

technical field [0001] The present disclosure relates to an information processing device, an information processing method, and a program. More specifically, the present disclosure relates to an information processing device, an information recording medium, an information processing method, and a program capable of high-density recording to realize large-capacity data recording. Background technique [0002] As a recording medium for recording various data, an optical disc such as a digital versatile disc (DVD) or a Blu-ray (registered trademark) disc (BD) is often used. [0003] In general, an optical disc is formed of lands (ridges) and grooves (valleys). With the land and groove configuration, it is possible to perform a tracking process specifying a track position even in a data-unrecorded state. [0004] In conventional discs in the past, data recording processing was performed only on grooves, but data recording was not performed on lands on either side of the groo...
