Abstract

A recording medium conforming with a specific physical format of DVD or the like is contrived to achieve superior sound quality in audio data recording and reproduction, common usability of data, and enhanced interchangeability of apparatus. In this recording medium, identification data signifying the existence of recorded data of a second data format (DSD) different from a first data format (DVD) is included in physical format management information recorded in a lead-in area. The data of such second data format is recorded in a data area in conformity with the physical format management information. Second data management information (TOC) is recorded at a predetermined position to manage an operation of reproducing the data of the second data format.
