Recording apparatus, recording method, and sparing destination selecting method

A recording method comprising:

• executing recording of information by laser irradiation on a recording position specified according to a recording request on a recording medium having a plurality of layers serving as recording layers where recording of information is performed by laser irradiation, and a track serving as a continuous recording area is formed, and recording of data is performed within a track, and also a plurality of tracks are set to one layer according to recording purpose;
• and
• determining, in the event that sparing processing occurs, a sparing destination by sparing destination selecting processing where as a first priority the next recording address of a track being recorded is selected as a sparing destination, and as a second priority the next recording address of a track overlapped with a track where recording is performed according to the recording request in a layering direction of the layers is selected as a sparing destination, and sparing recording is executed.

A sparing destination selecting method in a case where sparing processing of a recording position occurs on a recording medium having a plurality of layers serving as recording layers where recording of information is performed by laser irradiation, and a track serving as a continuous recording area is formed in the plurality of layers, and recording of data is performed within a track, and also a plurality of tracks are set to one layer according to recording purpose, the method comprising:

• selecting, as a first priority, the next recording address of a track being recorded as a sparing destination;
• and
• selecting, as a second priority, the next recording address of a track overlapped with a track where recording is performed according to the recording request in a layering direction of the layers as a sparing destination.
