A data recording and reproducing configuration in which both of BDMV standard compliant data and BDMV standard non-compliant data can be used is realized. A plurality of directories are set in a recording media, and a recording destination directory is selected according to the types of data. The BDMV standard compliant data is recorded in a BDMV directory, and the BDMV standard non-compliant data, for example, 1080/60p or 3D image data are recorded in a BDAV or BU directory. At the time of data reproducing process, a virtual file system in which the recorded data in the BDMV directory and the recorded data in the BDAV/BU directory are consolidated is constructed to achieve the reproducing process. With this configuration, the recording and reproducing of the BDMV standard compliant data and the BDMV standard non-compliant data are achieved.
