METHOD AND APPARATUS FOR RECORDING OR REPRODUCING ON OR FROM OPTICAL MEDIUM USING SBM INFORMATION
First Claim
1. A method for recording data onto a recording medium having a recording layer, the recording layer including an inner area, a data area and an outer area, the data area having a user data area and a spare area, the user data area consisting of a plurality of clusters, the method comprising steps of:
- (a) recording a first data block having a temporary defect list for managing a defective area of the data area onto a temporary defect management area allocated in the inner area or the spare area; and
(b) recording a second data block having a space bitmap onto the temporary defect management area, the space bitmap including layer information indicating a layer number of the recording layer to which the bitmap data is applied, bitmap data indicating whether or not each cluster in the user data area on the recording layer contains recorded data, first position information of a start cluster of the user data area on the recording layer,wherein each of the first and second data blocks contains second position information indicating a position of a latest temporary defect list recorded in the temporary defect management area and second position information indicating a position of a latest space bit map recorded in the temporary defect management area.
