Abstract
An information recording medium, a method of recording and/or reproducing data to/from the medium, and a recording/reproducing apparatus using the medium, the medium having a data area including a user data area to record user data, and a spare area to record replacement blocks that replace defect blocks occurring in the user data area, wherein defect list entries include status information of the defect blocks and the replacement blocks, and the status information of the defect blocks in the user data area is changed, and the status information of the replacement blocks in the spare area is changed, in response to the spare area being newly allocated to re-initialize the medium.
Claims (6)
1. An information recording medium accessible by a recording and/or reproducing apparatus, the information recording medium comprising:
a data area comprising a user data area to store user data and a spare area to store a replacement block that replace a defective block occurring in the user data area; and a defect management area to store a defect list in which a defect entry is recorded, the defect entry comprising location information regarding the defective block and the replacement block and first status information regarding the defective block and the replacement block;
wherein the defect entry with first status information is converted to new defect entry with second status information during re-initialization, if the defective block remains in the user data area after range of the spare area is changed by re-initialization.
a data area comprising a user data area to store user data and a spare area to store a replacement block that replace a defective block occurring in the user data area; and a defect management area to store a defect list in which a defect entry is recorded, the defect entry comprising location information regarding the defective block and the replacement block and first status information regarding the defective block and the replacement block;
wherein the defect entry with first status information is converted to new defect entry with second status information during re-initialization, if the defective block remains in the user data area after range of the spare area is changed by re-initialization.
2. The information recording medium of claim 1, wherein a physical address of the defective block is not changed.
3. An apparatus for recording data on an information recording medium comprising:
a pickup which emits a light to transfer data with respect to the information recording medium comprising a data area comprising a user data area to store user data and a spare area to store a replacement block that replace a defective block occurring in the user data area, and a defect management area to store a defect list in which a defect entry is recorded, the defect entry comprising location information regarding the defective block and the replacement block and first status information regarding the defective block and the replacement block; and a controller which controls the pickup to record a new defect entry with second status information into which the defect entry with first status information is converted during re-initialization, if the defective block remains in the user data area after range of the spare area is changed by re-initialization.
a pickup which emits a light to transfer data with respect to the information recording medium comprising a data area comprising a user data area to store user data and a spare area to store a replacement block that replace a defective block occurring in the user data area, and a defect management area to store a defect list in which a defect entry is recorded, the defect entry comprising location information regarding the defective block and the replacement block and first status information regarding the defective block and the replacement block; and a controller which controls the pickup to record a new defect entry with second status information into which the defect entry with first status information is converted during re-initialization, if the defective block remains in the user data area after range of the spare area is changed by re-initialization.
4. The apparatus of claim 3, wherein a physical address of the defective block is not changed.
5. An apparatus for reproducing data from an information recording medium comprising:
a pickup which emits and receives a light to transfer data with respect to the information recording medium comprising a data area comprising a user data area to store user data and a spare area to store a replacement block that replace a defective block occurring in the user data area, and a defect management area to store a defect list in which a defect entry is recorded, the defect entry comprising location information regarding the defective block and the replacement block and first status information regarding the defective block and the replacement block; and a controller which controls the pickup to read a new defect entry with second status information from the information recording medium, wherein the new defect entry with second status information is an entry which is converted from the defect entry with first status information during re-initialization, if the defective block remains in the user data area after range of the spare area is changed by re-initialization.
a pickup which emits and receives a light to transfer data with respect to the information recording medium comprising a data area comprising a user data area to store user data and a spare area to store a replacement block that replace a defective block occurring in the user data area, and a defect management area to store a defect list in which a defect entry is recorded, the defect entry comprising location information regarding the defective block and the replacement block and first status information regarding the defective block and the replacement block; and a controller which controls the pickup to read a new defect entry with second status information from the information recording medium, wherein the new defect entry with second status information is an entry which is converted from the defect entry with first status information during re-initialization, if the defective block remains in the user data area after range of the spare area is changed by re-initialization.
6. The apparatus of claim 5, wherein a physical address of the defective block is not changed.
