27. A method of recording information to a disk recording medium having at least a first layer and a second layer, comprising:
recording dummy data, recording increment by recording increment, on data areas of each of the first and second layers,
wherein, within the data areas of the first and second recording layers, the dummy data recording increments are recorded from an inner side toward an outer side of the data areas, and
wherein, within each recording increment of the data area of the first layer, the dummy data is recorded from an inner side toward an outer side of the recording increment, and, within each recording increment of the data area of the second layer, the dummy data is recorded from an outer side toward an inner side of the recording increment.
28. The method as claimed in claim 27, further comprising:
receiving a request to eject the disk recording medium from a host during the recording of the dummy data; and
recording a data management area prior to ejecting the disk recording medium.
29. An apparatus for recording information to a disk recording medium having at least a first layer and a second layer, the first layer having a data area having an outer side and an inner side and a second layer having a data area having an outer side and an inner side, comprising:
a recording part to record dummy data on the data areas of each of the first and second layers, wherein dummy data is recorded recording increment by recording increment;
wherein, within the data areas of the first and second recording layers, the dummy data recording increments are recorded from the inner side toward the outer side of the data areas, and
wherein, within each recording increment of the data area of the first layer, the dummy data is recorded from an inner side toward an outer side of the recording increment, and, within each recording increment of the data area of the second layer, the dummy data is recorded from an outer side toward an inner side of the recording increment.
30. The apparatus as claimed in claim 29, wherein when a request to eject the disk recording medium is received from a host during recording of the dummy data, the disk recording medium is ejected after recording a data management area.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
