Recording device and method, salvage device and method, and program

A recording method for recording data managed as files onto a recording medium, comprising:

• a generating step for generating a marker that contains a recognition pattern set beforehand for each of segment files in which at least one of the files is segmented, and salvage processing information that is used in a salvage process of a file that is recorded on the recording medium but in an unrecognizable state as a file, and
• a recording step for recording the segment file and the marker onto the recording medium so that the segment file and the marker are arranged on the recording medium in a predetermined order,
• wherein the salvage processing information contains information indicating a planned recording position, on the recording medium, of a following marker that is recorded on the recording medium in succession to the marker containing the salvage processing information,
• wherein, when a defect takes place at the planned recording position, the following marker is shifted to an actual recording position rightward to the planned recording position.

A computer-readable medium storing a program that when executed on a computer causes a recording processing for recording data managed as files onto a recording medium, the program comprising:

• a generating step for generating a marker that contains a recognition pattern set beforehand for each of segment files in which at least one of the files is segmented, and salvage processing information that is used in a salvage process of a file that is recorded on the recording medium but in an unrecognizable state as a file, and
• a recording control step for controlling the recording of the segment file and the marker on the recording medium so that the segment file and the marker are arranged on the recording medium in a predetermined order,
• wherein the salvage processing information contains information indicating a planned recording position, on the recording medium, of a following marker that is recorded on the recording medium in succession to the marker containing the salvage processing information,
• wherein, when a defect takes place at the planned recording position, the following marker is shifted to an actual recording position rightward to the planned recording position.

A salvage apparatus comprising:

• determining means for determining whether a recording process for recording a marker and a segment file on a recording medium in a predetermined order is normally completed, wherein the marker contains a recognition pattern set beforehand for each of the segment files in which at least one of files is segmented, and salvage processing information that is used in a salvage process of a file that is recorded on the recording medium but in an unrecognizable state as a file,
• detecting means for detecting at least one of the markers recorded on the recording medium based on the recognition pattern if the determining means determines that the recording of the file to the recording medium is not normally completed,
• identifying means for identifying data formed of the same file based on the salvage processing information contained in the marker, and
• registering means for registering the data identified by the identifying means as the data of the same file in a file system,
• wherein the salvage processing information contains information indicating a planned recording position, on the recording medium, of a following marker that is recorded on the recording medium in succession to the marker containing the salvage processing information,
• wherein, when a defect takes place at the planned recording position, the following marker is shifted to an actual recording position rightward to the planned recording position.
