Abstract
The present invention relates to a method of searching for a recordable position of a writable disk, the method comprising the steps of (a) reading data recording information of the writable disk, the data recording information indicating a position of a last track recorded and a recordable position for data to be recorded; (b) examining whether or not an area after the recordable position indicated by the read data recording information has recorded data; and (c) determining whether to change the recordable position to another position for new input data based on the examination result.
Claims23
A method of recording data in a recording medium, comprising:
- (a) reading data recording information of the recording, the data recording information indicating a last recorded position and a recordable position for new data to be recorded;
- (b) examining whether or not an area corresponding to the recordable position has an already recorded data;
- and
- (c) determining whether to change the recordable position to another position for recording the new data based on the examination result, the another position being physically separated from the recordable position indicated by the read data recording information, wherein the step (c) includes identifying another position for recording the new data if the area has the already recorded data.
A method of recording data in a recording medium, comprising:
- (a) searching a last position of data recorded previously based on a position information;
- (b) examining a recording area affected by a writing beam during the previous recording based on the searched last position;
- and
- (c) determining a new recordable position for recording new input data based on the examination result, wherein the step (c) includes searching the new recordable position separated from the recording area if the recording area includes an already recorded data as a result of the examination result.
A method of recording data in a recording medium, comprising:
- (a) determining whether a first area to record new data has been recorded already;
- and
- (b) altering a position for recording the new data to a new second area separated from the first area if the first area has been recorded already as a result of the step (a), while closing an area including the first area so as not to record data thereon no longer if the area including the first area is not in a closed status.
A method of recording data in a recording medium, comprising:
- (a) determining whether old data has been already in a first position to record new data;
- and
- (b) altering the first position to record the new data to a second position separated from a first area including the first position if the old data has been recorded already as a result of the step (a), thereby not overwriting physically the new data on the old data recorded already in the first area, while adding a padding data between the first area and the second position.
