US 7362675 B2Abstract
1. A recording and/or reproducing apparatus, comprising:
a controller which controls the recording and/or reproducing unit to record area allocation information, which indicates whether at least one section of a data area of the disc is allocated for disc defect management in a temporary disc defect structure (TDDS) of a temporary defect management area (TDMA) formed in a predetermined area of the disc, wherein the area allocation information recorded in the temporary disc defect structure (TDDS) is recorded in a defect management area (DMA).
3. An information storage medium, comprising:
a lead-in area comprising a first temporary disc management area comprising a first temporary disc defect structure including a first information which indicates whether at least one section of the data area is allocated for defect management and a second information which specifies a size of a second temporary disc management area allocated in the data area,
wherein a copied information of the first information and the second information of the first temporary disc defect structure is recorded in a defect management area of the lead-in area.
4. The medium of claim 3, wherein the first information comprises size information specifying a size of the at least one section allocated in the data area.
This application is a continuation of U.S. patent application Ser. No. 10/797,050, filed Mar. 11, 2004, now pending, which claims the priorities of Korean Patent Application No. 2003-15858 filed on Mar. 13, 2003, Korean Patent Application No. 2003-19964 filed on Mar. 31, 2003, and Korean Patent Application No. 2004-7533 filed on Feb. 5, 2004, and U.S. Provisional Patent Application No. 60/477,955 filed on Jun. 13, 2003, the disclosures of which are incorporated herein in their entirety by reference.
FIG. 11 illustrates a detailed structure of the TDMA#1 shown in FIG. 10;
After recording a TDDS #0, an SBM #0 is recorded in a first cluster of the SBM area. In the bit map of the SBM #O, a bit corresponding to the position of a first cluster of a TDDS and a bit corresponding to the position of the first cluster are expressed with 1, and bits corresponding to the remaining clusters are expressed with 0.
FIG. 10 illustrates a structure of a single record layer disc allowing management of a data area, according to an embodiment of the present invention. Unlike the disc according to the embodiments described above, the disc of FIG. 10 further includes a TDMA#2 in a data area, in addition to a TDMA #1 in a lead-in zone.
The TDMAs #1 and #2 are different from each other in that updated information is recorded in the TDMA #1 either before ejecting of a disc from a recording/reproducing apparatus or during disc initialization, and updated information is recorded in the TDMA#2 in operation units during the recording of data on the disc. Here, the operation units are units in which a verify-after-write method is facilitated. In the verify-after-write method, data is recorded in cluster units and then verified.
Even if spare areas are allocated to the-data area and the disc is initialized by recording area allocation information that indicates the allocation, the structure of the data area may be changed by re-initializing the disc and updating the area allocation information.
