- the information recording apparatus can record a plurality of pieces of recording information recorded in correspondence with a series of recording operations, separately from each other or at the same opportunity. For example, when one information recording medium is loaded on one information recording device, at another opportunity after the main power supply is turned on or off, or between multiple information recording devices, one information recording medium is further loaded and unloaded.
- a single information recording medium is recorded at another opportunity, such as recording a single piece of content or file as recorded information at another opportunity after loading.

Therefore, when additional recording processing is performed at different occasions, the first recording layer is an area in which recording information is recorded and overlaps with the second recording medium by a player or the like between the additional recording processes. It is possible to reliably prevent the recording layer from becoming an unrecorded area, thereby avoiding a situation in which the recorded information cannot be reproduced.
- the unit of information recording medium such as finalization processing described above is not used for dummy data. Compared to the case where the recording area is filled, processing can be performed quickly. Even after filling with dummy data in this way, it is of course possible to add the next recorded information as described above, and compared with the finalizing process, which makes subsequent writing impossible.

Thus, it is possible to reliably prevent the second recording layer from becoming an unrecorded area, thereby avoiding a situation in which recorded information cannot be reproduced.
- dummy data is recorded in units of information recording media such as the finalizing process described above.
- the processing can be performed quickly.
- a recording area that is filled with dummy data that is, a wasteful recording area, remains within each unit of the recording information, and therefore can be relatively small. Even after filling with dummy data in this way, it is of course possible to add the next recorded information as described above, and it is advantageous to each stage as compared with the finalizing process in which the subsequent writing is impossible.

Cannot read the information. That is, in this case, compatibility between the recorder and the player cannot be achieved. Conversely, if dummy data or the like is written in the unrecorded area 210 of the L1 layer following the last BO and a process such as finalization can be performed, the player or the like can read the user data. However, if finalization is performed in this way, user data can no longer be written to the data area following the last BO.

- an unrecorded area 102D it is filled with dummy data.
- the data area 102 is a portion where the recording capacity is wasted as much as the unrecorded area 102D is filled with dummy data, but the player and the like are also filled with the dummy data.
- the optical disc 100 including can be reproduced without problems by the same reproduction process as shown in FIG. That is, compatibility can be ensured.
- the dummy area is a unit of bordered area.
- the size of the data area 102 to be wasted is much smaller because it only needs to be filled with data. However, even after processing with dummy data, additional processing is possible in the next border area, which is particularly advantageous.
- the process of filling the unrecorded area 102D with dummy data is generally applied to the intermediate force of the L1 layer or the force that applies to the entire L1 layer. It doesn't matter. In any case, when performing a recording process that is shortened unscheduled, the recording capacity of the optical disc 100 can be saved as much as possible.
- an information recording / reproducing apparatus for a write-once optical disc such as a two-layer DVD-R has been described. It can be applied to an information recording / reproducing apparatus for a rewritable optical disc such as a two-layer DVD-RW.
- the present invention can be applied to an information recording / reproducing apparatus for a multiple layer type optical disc such as a three layer type.
- the present invention can be applied to an information recording / reproducing apparatus for a large-capacity recording medium such as a disk using a blue laser for recording / reproducing.
- each recording layer in a two-layer type or multilayer type optical disc has a recording area that is compatible with a player or the like. Recording is possible without wasting.
- the information recording apparatus and method and the computer program according to the present invention can be used for an information recording apparatus such as a DVD recorder, for example. Further, the present invention can also be used for an information recording device or the like that is mounted on or connectable to various computer equipment for consumer use or business use.
