The terminology used in the present invention was selected as a general term that is widely used at present, but in some cases, the term is arbitrarily selected by the applicant, and in this case, the meaning of the term is described in detail in the description of the present invention. The present invention should be understood as meanings other than terms.

In this context, the term " recording medium " in the present invention means any medium in which data is recorded or can be recorded, and encompasses all mediums regardless of a recording method such as an optical disc 30, a magnetic tape, or the like. to be. Hereinafter, the present invention will be described by using an optical disc 30, in particular "Blu-ray Disc (BD)" as a recording medium for convenience of description, but the technical concept of the present invention is the same for other recording media including DVD. Applicability is obvious.

In the following examples, the same reference numerals are used for the same or similar components.

Blu-ray discs may be of a first type having a storage capacity of approximately 25GB in one recording layer and a second type storing approximately 32GB or 33GB in one recording layer. In this embodiment, if a storage capacity of approximately 33 GB is stored in one recording layer and the disk has three recording layers, approximately 100 GB of data can be stored in one disk. Alternatively, if a storage capacity of approximately 32 GB is stored in one recording layer and the disk has four recording layers, approximately 128 GB of data can be stored in one disk. Thus, a type having about 33GB data storage capacity in one recording layer can significantly increase the recording capacity compared with 25GB. Here, a type having a storage capacity of 33 GB in one recording layer compared to a type having a storage capacity of 25 GB in one recording layer is a physical cluster provided in one recording layer by increasing the frequency of the wobble of the recording medium. Increase the number of clusters.

As shown, the disk of the first type has a wobble frequency of about 956.522 kHz, whereas the disk of the second type has a wobble frequency of 1262.609 kHz. Here, the wobble frequency of the disk of the second type can be adjusted within a range larger than the wobble frequency of the disk of the first type. Referring to the structure of the recording layer of FIG. 2 to be described later, in the case of the physical cluster included in the inner zone except for the PIC region in the first recording layer L0, the first type is 4832 and the second type is It may have 6378, which is 1546 more than the first type. In addition, the number of physical clusters of the inner region in the second recording layer L1 may include 12503, which is increased by 9472 for the first type and 3031 for the second type. The number of physical clusters included in the data zone of the first recording layer L0 and the second recording layer L1 is 381856 for the first type, and 504050 for the second type, which is increased by 122194. have. The number of physical clusters included in the outer zone is 780 for the first type and 1030 added to 250 for the second type. Here, the number of physical clusters included in each region of the second type may be changed within many ranges compared to the first type. In addition, FIG. 1 discloses a disc of a first type only when the number of recording layers is one (SL) or two (DL), and the second type has a plurality of recording layers, for example, three ( TL) or four (QL) is disclosed.

The above-described first type optical disc 30 and the second type optical disc 30 have a physically similar size and thickness. For example, each optical disk 30 may have a diameter of 120 mm and a thickness of 1.2 mm. Further, as described above, the position of the start point and the end point of each region on the disc plane or in the advancing direction of pickup 11 to be described later for recording and reproducing the data of the disc by adjusting the number of clusters of the disc of the second type Becomes similar. Therefore, even if the capacities differ from each other, the specifications of each type of disk are similar.

The structure (TDDS) records various necessary information on the disc, including defect management and general management. That is, the temporary disk definition structure (TDDS) may include information on the format and status of the disk.

And, management information will be recorded in the temporary disk management structure (TDMS) whenever an update is needed, but the temporary disk list (TDFL) or sequential record is always updated since the TDDS should always record the latest information. The data is recorded together with the range information (or space bitmap information). As information recorded in the temporary disk definition structure TDDS, for example, position information of the latest temporary defect list TDFL (or sequential recording range information SRRI or space bitmap information SBI) is recorded.

Can be recorded in the form of space bitmap information (SBM) as another management information instead of the sequential recording range information SRRI.

Furthermore, when there is no longer a recordable user data area or a temporary defect management area (TDMA) in the optical disc 30, or when the user no longer wants to write to the disc, the disk is closed. In this case, the latest defect management information recorded last in the defect management information recorded in the temporary defect management area (TDMA) is transferred into the DMA.

In this regard, the term " recording range " in the present invention means an area created (allocated) for data recording in the optical disc 30 which can be written once.
