Abstract: A data recording/playing configuration capable of recording different attribute information according to methods of coding a 3D image and decoding according to the coding method, by acquiring attribute information. A method of coding a 3D image included in data to be recorded in a recoding medium is determined; attribute information to be recorded in a management information file is changed according to the determined coding method; and attribute information unique to each coding method is recorded in the management information file. For example, if the coding method is a frame sequential method, frame identification data indicating whether a frame constituting the 3D image is a left-eye image or a right-eye image is recorded as the attribute information. A playing apparatus acquires information unique to the coding method from the attribute information, so a decoding process corresponding to the coding method can be performed without error.

Abstract: On a recording medium, there are recorded content files and an index file. The index file is constituted by attribute information of the content files (title text data, thumbnail-image data or the like).

Abstract: A method for recovering video data in a disk when a reading error occurs is provided. First, the disk is scanned to obtain a next writable address (NWA) of a last video chapter previously recorded into the disk. An end address of a successfully recorded video chapter is then read from a specific area of the disk and stored into a memory. Next, when a disk player/recorder is requested to read content of data according to the NWA, the disk player/recorder determines whether the content of the data is a file system. If the content of the data is not a file system, the NWA obtained by scanning the disk is replaced with the end address read from the specific area to read the file system, so as to recover the video data in the disk. Thereby, the video data in the disk can be protected.
