Abstract

A method of recording a temporary defect list on a write-once recording medium, a method of reproducing the temporary defect list, an apparatus for recording and/or reproducing the temporary defect list, and the write-once recording medium. The method of recording a temporary defect list for defect management on a write-once recording medium includes recording the temporary defect list, which is created while data is recorded on the write-once recording medium, in at least one cluster of the write-once recording medium, and verifying if a defect is generated in the at least one cluster. Then, the method includes re-recording data originally recorded in a defective cluster in another cluster, and recording pointer information, which indicates a location of the at least one cluster where the temporary defect list is recorded, on the write-once recording medium.

Claims

1. An apparatus for recording data on a write-once recording medium, the apparatus comprising:

a pickup which emits a light to transfer data with respect to the write-once recording medium; and

a controller which generates a temporary defect list comprising a first pointer indicating the defective cluster of a user data area of the write-once recording medium and a second pointer indicating a replacement cluster of a spare area of the write-once recording medium corresponding to the defective cluster, which controls the pickup to record the temporary defect list in a plurality of clusters of a temporary defect management area of the write-once recording medium, in which a portion of the temporary defect list is recorded, and when a defect is detected in a first cluster among the plurality of clusters, a remaining portion of the temporary defect list is recorded from a second cluster next to the first cluster, and which controls the pickup to record a temporary disc definition structure comprising a plurality of third pointers indicating the plurality of clusters in which the temporary defect list is recorded, respectively, excluding the first cluster.

2. An apparatus for reproducing data from a write-once recording medium, the apparatus comprising:

a pickup which emits and receives a light to transfer data with respect to the write-once recording medium; and

a controller which controls the pickup to read a temporary disc definition structure comprising a plurality of third pointers indicating a plurality of clusters in which a temporary defect list is recorded, respectively, excluding a first cluster, from the write-once recording medium, the temporary defect list comprising a first pointer indicating the defective cluster of a user data area of the write-once recording medium and a second pointer indicating a replacement cluster of a spare area of the write-once recording medium corresponding to the defective cluster, and which controls the pickup to access the plurality of clusters where the temporary defect list is recorded, excluding a first cluster, according to the temporary disc definition structure,

wherein a portion of the plurality of clusters contains a portion of the temporary defect list, and when the first cluster among the plurality of clusters has a defect, a remaining portion of the plurality of clusters, which starts from a second cluster next to the first cluster, contains a remaining portion of the temporary defect list.

3. A write-once recording medium, comprising:

a temporary defect list comprising a first pointer indicating a defective cluster of a user data area of the write-once recording medium and a second pointer indicating a replacement cluster of a spare area of the write-once recording medium corresponding to the defective cluster; and

a temporary disc definition structure comprising a plurality of third pointers indicating a plurality of clusters in which a temporary defect list is recorded, respectively, excluding a first cluster; and

wherein a portion of the plurality of clusters contains a portion of the temporary defect list, and when the first cluster among the plurality of clusters has a defect, a remaining portion of the plurality of clusters, which starts from a second cluster next to the first cluster, contains a remaining portion of the temporary defect list.
