Abstract
The data structure on the recording medium includes a temporary defect management area storing a data block. The data block includes a space bit map and a temporary definition structure. The space bit map indicates recordation status of the data area, and the temporary definition structure provides a pointer to the space bit map.
Claims24
A recording medium having a data structure for managing a data area of the recording medium, comprising:
- a temporary defect management area storing a first data block, the first data block including a space bit map and a temporary definition structure, the space bit map indicating recordation status of the data area, and the temporary definition structure providing a first pointer to the space bit map.
A method of recording management data on a recording medium, comprising:
- recording a first data block in a temporary defect management area, the first data block including a space bit map and a temporary definition structure, the space bit map indicating recordation status of the data area, and the temporary definition structure providing a first pointer to the space bit map.
A method of reproducing data from a recording medium, comprising:
- reproducing at least a portion of data recorded on the recording medium based on a first data block recorded in a temporary defect management area of the recording medium, the first data block including a space bit map and a temporary definition structure, the space bit map indicating recordation status of the data area, and the temporary definition structure providing a first pointer to the space bit map.
An apparatus for recording management data on a recording medium, comprising:
- a driver for driving an optical recording device to record data on the recording medium;
- and
- a controller for controlling the driver to record a first data block in a temporary defect management area, the first data block including a space bit map and a temporary definition structure, the space bit map indicating recordation status of the data area, and the temporary definition structure providing a first pointer to the space bit map.
