Information recording medium, information recording apparatus and method, and computer program

An information recording medium which can be rewritable comprising:

• a data recording area to which one attribute, which corresponds to recorded data, of a plurality of types of attributes is given in each of segmentized area units;
• and
• an address recording area to record therein an address of an edge portion on an outermost side of a recording area, which is a continuous recording area to which a data area attribute of the plurality of types of attributes is given and which is a recording area closest to an edge portion on an innermost side of said data recording area, the data area attribute indicating a status that user data is recorded as the data.

An information recording apparatus comprising:

• a first recording device for recording data onto an information recording medium which can be rewritable, while giving one attribute, which corresponds to the recorded data, of a plurality of types of attributes in each of segmentized area units;
• and
• a second recording device for recording, onto the information recording medium, an address of an edge portion on an outermost side of a recording area, which is a continuous recording area to which a data area attribute of the plurality of types of attributes is given and which is a recording area closest to an edge portion on an innermost side of said data recording area, the data area attribute indicating a status that user data is recorded as the data.

An information recording apparatus comprising:

• a first recording device for recording data onto an information recording medium which can be rewritable, while giving one attribute, which corresponds to the recorded data, of a plurality of types of attributes in each of segmentized area units;
• and
• a formatting device for performing a format process on the information recording medium, with reference to an address of an edge portion on an outermost side of a recording area, which is continuous recording area to which a data area attribute of the plurality of types of attributes is given and which is a recording area closest to an edge portion on an innermost side of said data recording area, the data area attribute indicating a status that user data is recorded as the data.
