Abstract
An information recording medium is provided with: a recording area divided into a plurality of partial areas; and an information area for recording therein (i) management information for managing recording conditions of the plurality of partial areas at least for each of the plurality of partial areas and (ii) reliability information for indicating reliability of the management information for each of the plurality of partial areas.
Claims11
An information recording medium comprising:
- a recording area divided into a plurality of partial areas in advance;
- and
- an information area for recording therein (i) management information for managing recording conditions of the plurality of partial areas at least for each of the plurality of partial areas and (ii) reliability information for indicating reliability of the management information for each of the plurality of partial areas.
An information recording apparatus for recording data onto an information recording medium comprising:
- a recording area divided into a plurality of partial areas;
- and an information area for recording therein (i) management information for managing recording conditions of the plurality of partial areas at least for each of the plurality of partial areas and (ii) reliability information for indicating reliability of the management information for each of the plurality of partial areas,
- said information recording apparatus comprising:
- a reading device for reading the management information from said information area;
- a determining device for determining at least one of the plurality of partial areas, which is managed by the management information read by said reading device, as a data recording-area for recording the data;
- a first updating device for temporarily updating the reliability information, which corresponds to the management information for managing the determined data-recording-area, to information for indicating to be unreliable;
- a recording device for recording the data into the determined data-recording-area;
- and
- a second updating device for updating the management information after recording of the data is completed and for definitely updating the reliability information, which corresponds to the updated management information, to information for indicating to be reliable.
An information recording method of recording data onto an information recording medium comprising:
- a recording area divided into a plurality of partial areas;
- and an information area for recording therein (i) management information for managing recording conditions of the plurality of partial areas at least for each of the plurality of partial areas and (ii) reliability information for indicating reliability of the management information for each of the plurality of partial areas,
- said information recording method comprising:
- a reading process of reading the management information from said information area;
- a determining process of determining at least one of the plurality of partial areas, which is managed by the management information read by said reading process, as a data-recording-area for recording the data;
- a first updating process of temporarily updating the reliability information, which corresponds to the management information for managing the determined data-recording-area, to information for indicating to be unreliable;
- a recording process of recording the data into the determined data-recording-area;
- and
- a second updating process of updating the management information after recording of the data is completed and of definitely updating the reliability information, which corresponds to the updated management information, to information for indicating to be reliable.
