Method of managing defects for a write-once recording medium, reproducing and/or recording apparatus implementing the same, a corresponding write-once recording medium therefor, and medium including computer readable code controlling the implementation of the same

A method of managing defects on a recording medium having a single recording layer on which a lead-in area, a data area, and a lead-out area are sequentially disposed, the data area having a first spare area and a second spare area at the respective opposite ends thereof, the method comprising:

• allocating a first temporary defect management area to at least one of the lead-in area and the lead-out area of the recording medium;
• allocating a second temporary defect management area between the first spare area and a user data area or between the user data area and the second spare area;
• performing defect management for the recording medium using the first and second temporary defect management areas;
• and
• writing full flag information, indicating that one of the first and second temporary defect management areas is exhausted, to the other one of the first and second temporary defect management areas, when the one of the first and second temporary defect management areas is exhausted.

A method of managing defects on a recording medium having a first recording layer and a second recording layer, the first recording layer including a lead-in area, a data area, and an outer area which are sequentially disposed according to a recording path wherein the data area of the first recording layer has a first spare area and a second spare area at the respective opposite ends thereof, the second recording layer including an outer area, a data area, and a lead-out area which are sequentially disposed according to the recording path wherein the data area of the second recording layer has a third spare area and a fourth spare area at the respective opposite ends thereof, the method comprising:

• allocating a first temporary defect management area to at least one among the lead-in area, the lead-out area, and the outer areas of the recording medium;
• allocating a second temporary defect management area between the first spare area and a user data area and/or between the fourth spare area and the user data area;
• performing defect management for the recording medium using the first and second temporary defect management areas;
• and
• writing full flag information, indicating that one of the first and second temporary defect management areas is exhausted, to the other one of the first and second temporary defect management areas when the one of the first and second temporary defect management areas is exhausted.

A write-once recording medium having a single recording layer on which a lead-in area, a data area, and a lead-out area are sequentially disposed, the data area having a first spare area, a user data area, and a second spare area which are sequentially disposed, the write-once recording medium comprising:

• a defect management area provided in at least one of the lead-in area and the lead-out area including defect management information for performing defect management of the write-once recording medium during playback;
• a first temporary defect management area provided in at least one of the lead-in area and the lead-out area including temporary management information recorded to the write-once recording medium with a predetermined period;
• and
• a second temporary defect management area provided between the first spare area and the user data area or between the user data area and the second spare area including temporary management information recorded to the write-once recording medium with a period different from the predetermined period,
• wherein full flag information, indicating whether the second temporary defect management area is exhausted, is recorded in the first temporary defect management area, and full flag information, indicating whether the first temporary defect management area is exhausted, is recorded in the second temporary defect management area.

A write-once recording medium having a first recording layer and a second recording layer, the first recording layer including a lead-in area, a data area, and an outer area which are sequentially disposed according to a recording path and wherein the data area has a first spare area and a second spare area at the respective opposite ends thereof, the second recording layer including an outer area, a data area, and a lead-in area which are sequentially disposed according to the recording path and wherein the data area has a third spare area and a fourth spare area at the respective opposite ends thereof, the write-once recording medium comprising:

• a defect management area provided in at least one of the lead-in area, the lead-out area, and the outer areas, including defect management information;
• a first temporary defect management area provided in at least one of the lead-in area, the lead-out area, and the outer areas, including temporary management information recorded to the write-once recording medium with a predetermined period;
• and
• a second temporary defect management area provided between the first spare area and the user data area of the first recording layer and/or between the fourth spare area and the user data area of the second recording layer, including temporary management information recorded to the write-once recording medium with a period different from the predetermined period,
• wherein full flag information, indicating whether the second temporary defect management area is exhausted, is recorded in the first temporary defect management area, and full flag information, indicating whether the first temporary defect management area is exhausted, is recorded in the second temporary defect management area.

A recording medium, comprising:

• a defect management area recording defect management information for defect management of user data recorded on the recording medium during playback of the user data;
• and
• a plurality of temporary defect management areas recording temporary management information for defect management, of a user data area, during recording of the user data on the recording medium, and including information on whether one of the plurality of temporary defect management areas has been exhausted, wherein
• upon finalization of the recording medium, temporary management information defect information recorded in one of the plurality of temporary defect management areas is recorded in the defect management area as the defect management information.
