For convenience of description, the recording medium is an optical disc, and in particular, a Blu-ray disc (BD) will be described as an example. However, the technical idea of the present invention is applicable to the recording medium as well as to the Blu-ray disc (BD). Will be self explanatory.

In addition, the terminology used in the present invention was selected as a general term widely used as possible, but in certain cases, the term is arbitrarily selected by the applicant, and in this case, since the meaning is described in detail in the corresponding description of the invention, the name of a simple term is used. It is intended that the present invention be understood as the meaning of the term.

In the present invention, " recording control information " in the present invention refers to information set by a user or a system, recorded in a management area in an optical disc or provided on a cartridge, and prohibiting data recording on the optical disc. Or information that permits recording.

In particular, the present invention is characterized in that when a plurality of recording control information (WP_flag) is recorded in the optical disc, after confirming these information and finally determining the recording prohibition or the recording permission by a combination of these information, The types and meanings of the plurality of recording control information WP_flag will be described in detail with reference to FIGS. 1 and 2 as follows.

1 is for conceptual understanding of the present invention.

The optical recorder 10 transmits data (which is a video / audio signal) to an optical disc 40 embedded in a cartridge 60 and an optical disc 40 without a cartridge 60 (also referred to as a "bare disc"). Or used in the same sense hereinafter) to record or reproduce and provide the same to a user through a specific display device 30. Therefore, the optical recorder 10 of the present invention is generally called a "Video Recorder" or "PC Drive" and the like, and it is obvious that the apparatus includes all devices capable of recording and reproducing an optical disc. .

In order for the optical recorder 10 to record data on the optical disk 40, the optical disk 40 must allow recording first, and recording cannot be performed on all or part of the optical disk where recording is prohibited.

That is, for example, in order to protect the recorded data, the first user who records specific data on the optical disc 40 may set write protection on all or a part of the optical disc. When the optical disc 40 to which write protection is set is loaded, the optical record player 10 cannot rewrite new data to the optical disc 40 or delete recorded data as intended by the first user. . Therefore, if write protection is not set on the optical disc 40, the optical recorder 10 recognizes that recording is freely permitted for the optical disc.

As a result, the "recording control information" of the present invention is used as information indicating whether or not the recording prohibition is set as described above, and is distinguished according to the position or the recorded area where the recording control information is set. This is largely divided into a case where it is recorded as specific information on the management area in the optical disc, and a case where a user-operable mechanical structure is formed on the cartridge 60 for protecting the optical disc. In the present invention, to distinguish the two cases, the former case will be named "WP (Write Protection) _flag (B)", and the latter case will be named "WP (Write Protection) _hole (A)".

In this regard, the "WP (Write Protection) _hole (A)" refers to a hole provided on the cartridge 60, depending on the opening or closing state of the hole. It is used as information for determining whether to prohibit recording. If a hole is opened, it means that recording is prohibited for the entire area of the optical disc 40 embedded in the cartridge 60. Is closed, it means that recording is allowed for the entire area of the optical disc 40 embedded in the cartridge 60. The determination of the opening or closing state of the hole is made by using a sensor (not shown) in the optical recorder 10, which is well known in the art, and a detailed description thereof will be omitted. I would like to.

In addition, "WP (Write Protection) _flag (B)" is information recorded for recording prohibition control in the management area in the optical disc 40. In particular, when "0b" is a 1-bit flag, Recording is allowed, and " 1b " is used to prohibit recording. However, a plurality of " WP (Write Protection) _flag (B) " recorded in the optical disc 40 can exist, and the management area and the purpose of existence are different. Hereinafter, the type and meaning of "WP (Write Protection) _flag (B)" will be described in detail with reference to FIG. 2.

Fig. 2 is a diagram for explaining the kind and significance of " WP (Write Protection) _flag (B) " set in the optical disc as recording control information of the present invention.                     

First, the structure of a Blu-ray disc (BD) to which the present invention is applied will be described. A lead-in area, a data area, and a lead-out area are sequentially arranged from the inner circumference of the disc. The data area includes a spare area for defect management and a user data area in which actual user data is recorded, and data to be recorded in the user data area. There is provided a management file area (hereinafter referred to as "MFA") for managing.

In the lead-in area, lead-out area, and management file area MFA, various types of management information for recording and reproducing a disc are recorded. "Area".

The management information recorded in the management area also includes a plurality of recording control information (WP_flag) according to the present invention, which will be described in detail below.

The first recording control information WP_flag 1 of the present invention is information recorded in a disc management area (DMA) in a lead-in area. When the recording data is to be prohibited in the entire data area, " 1b " If set to allow writing, "0b" (not write-protected) is set. In particular, the first recording control information (WP_flag 1, B1) is recorded in the Disc Definition Structure (DDS) in the DMA, and in a BD-R capable of recording an optical disc once, the TDDS (Temporary Disc in the Temporary Disc Management Area) is used during the disc use. Definition Structure).

The second recording control information WP_flag 2 of the present invention is recorded in the physical access control (PAC) area in the lead-in area, and is stored in a specific area managed by the PAC for the optical recorder 10 that does not recognize the PAC. As a rule for recording control for the recording (Unknown rule), for the specific area, "1b" (writing not allowable) is set when the recording is to be prohibited, and "0b" (writing allowable) when the recording is to be allowed. Will be set. In particular, the specific area managed by the PAC may be all or part of the user data area.

The third recording control information WP_flag 3 of the present invention is information recorded in a management file area (MFA) in the user data area, and prohibits recording on a specific area managed by a playlist file in the user data area. If you want to set "1b" (Not be changed or deleted), if you want to allow the recording "0b" (Free to change or delete) is set. In particular, the area managed by the PlayList file may be an entire or partial area of the user data area.

For convenience of description, " WP_flag 1 " recorded in the DMA is the first recording control information B1, and " WP_flag 2 " recorded in the PAC is the second recording control information B2, which is recorded in the MFA. "WP_flag 3" is intended to be named as the third recording control information B3.

Hereinafter, various embodiments of the recording control method of the optical recording / reproducing apparatus 10 when the optical disk provided with the above-described plurality of recording control information (B1, B2, B3) are loaded will be described with reference to FIGS. 3A to 6B. Is as follows.

First, the matters commonly applied in each embodiment will be described. First, " WP_hole " implemented on the cartridge as the recording control information always has priority. That is, if "WP_hole" is in an open state, it means that recording is prohibited on the entire disc area. In this case, regardless of the state of the recording control information (B1, B2, B3) recorded in the optical disc, Records are always prohibited. Therefore, the " WP_hole " is in a closing state, or a combination of the states of the recording control information (B1, B2, B3) recorded in the optical disc only in a disc without a cartridge is prohibited from recording in a specific area or Determination is made as to allow, and recording / reproduction control is performed accordingly. Embodiments of the present invention to be described below will focus on the case where "WP_hole" is a closed state or a "bare disc" without a cartridge.

Second, among the recording control information recorded in the optical disc, the second recording control information B2 and the third recording control information B3 respectively recorded in the PAC and the MFA are designated a disc specific area for recording control. It is obvious that there is no influence on each other when the specific areas to be controlled for recording are different. In the present invention, the recording control information (B2, B3) is set for the same area or some overlapping areas. To explain. For reference, since the first recording control information B1 recorded in the DMA is recording control information for the entire data area in the disc, the second recording control information B2 and the third recording control information B3 are always used for recording control. Regions overlap.

3A and 3B show a first embodiment of the recording control method of the present invention, characterized in that recording control is performed as a result of logically ORing all recording control information. That is, when any one of the plurality of recording control information B1, B2, B3 means recording prohibition, recording on the specific area is prohibited.

Therefore, when the first recording control information B1 is set to "1b" and recording is prohibited for the entire data area, the data area irrespective of the state of the second and third recording control information B2 and B3. Recording is prohibited for the whole (S31).

However, when the first recording control information B1 is set to "0b" and recording is permitted for the entire data area, both the second and third recording control information B2 and B3 are recorded as "0b". Is allowed, recording is allowed for the entire data area, but if any of the second and third recording control information (B2, B3) is prohibited as "1b", recording is prohibited for that specific area. It becomes (S32).

The first embodiment of the present invention is a preferred embodiment when the user intends to sufficiently reflect the intention of the user who has set the recording control information.

4A and 4B show a second embodiment of the recording control method of the present invention, characterized in that recording control is performed as a result of logically ANDing all the recording control information. In other words, when recording is allowed in any one of the plurality of recording control information B1, B2, B3, recording in the specific area is allowed.

Therefore, when the first recording control information B1 is set to " 0b " and recording is permitted for the entire data area, the data area irrespective of the state of the second and third recording control information B2 and B3. Recording is allowed for the whole (S41).

However, when the first recording control information B1 is set to "1b" and recording is prohibited for the entire data area, both the second and third recording control information B2 and B3 are also identified as "1b". If recording is prohibited for a region, recording for that specific area is prohibited, but if any of the second and third recording control information (B2, B3) permits recording as "0b", that particular area Records are allowed (S42).

The second embodiment of the present invention restricts the recording prohibition function for a specific area so that the recording prohibition is possible only when all the requirements are satisfied, so that the recording prohibition is not performed by a user unfamiliar with the use of the disc. Even if set, it is an embodiment suitable for solving this.

5A and 5B show a third embodiment of the recording control method of the present invention, wherein recording control is performed as a result of logically ORing and ANDing all recording control information. It is done. That is, among the plurality of recording control information (B1, B2, B3), logically ORing between the second and third recording control information (B2, B3), and the result and the first recording control information (B1). ) Is logically ANDed.

Therefore, when the first recording control information B1 is set to " 0b " and recording is permitted for the entire data area, the data area irrespective of the state of the second and third recording control information B2 and B3. Recording is allowed for the whole (S51).

However, when the first recording control information B1 is set to "1b" and recording is prohibited for the entire data area, both the second and third recording control information B2 and B3 are identified as "0b". If recording is allowed for an area, recording is allowed for that particular area, but if any of the second and third recording control information (B2, B3) is prohibited as "1b," Recording is prohibited (S52).                     

The third embodiment of the present invention restricts the recording prohibition function for a specific area so that recording can be prohibited only when all the requirements are satisfied, in particular, the first recording control information B1 means recording prohibition. In the case where any of the second and third recording control information (B2, B3) for a specific area means recording is prohibited, the recording is prohibited in the specific area.

6A and 6B show a fourth embodiment of the recording control method of the present invention, wherein recording control is performed as a result of logically ORing and ANDing all recording control information. It is done. That is, among the plurality of recording control information (B1, B2, B3), logically end (AND) between the second and third recording control information (B2, B3), and the result and the first recording control information (B1). Will logically end again.

Therefore, when the first recording control information B1 is set to " 0b " and recording is permitted for the entire data area, the data area irrespective of the state of the second and third recording control information B2 and B3. Recording is allowed for the whole (S61).

However, when the first recording control information B1 is set to "1b" and recording is prohibited for the entire data area, both the second and third recording control information B2 and B3 are also identified as "1b". When recording is prohibited for an area, recording for that specific area is prohibited, but if any of the second and third recording control information (B2, B3) permits recording as " 0b " Recording is allowed (S62).

The fourth embodiment of the present invention restricts the recording prohibition function for a specific area so that the recording can be prohibited only when all the requirements are satisfied. In particular, the first recording control information B1 means the recording prohibition. Even if any of the second and third recording control information (B2, B3) for the specific area means recording is allowed, the embodiment allows the recording of the specific area.

Fig. 7 shows the structure of the optical recording / reproducing apparatus of the present invention, wherein the pickup section 11 and the pickup section 11 for reading data and recording control information B1, B2, and B3 recorded in the optical disk are shown. The recovery signal received from the servo 14 and the pickup unit 11 controlling the operation is restored to a desired signal value, or the signal to be recorded is modulated into a signal recorded on the optical disc to the pickup unit 11. A signal processor 13 for transmitting, a memory 15 for temporarily storing file system information read from the optical disk, and a microcomputer 16 for controlling the operation are basically configured, and although not shown in the drawing, a sensor Means for checking the open or closed state of " WP_hole " as the recording control information provided on the cartridge. In relation to this, the above components may be referred to as a "recording / playing unit 20".

The microcomputer 16 transmits the read recording control information B1, B2, and B3 to the control unit 12 for use in recording and reproducing. The control unit 12 is an optical disk having a cartridge. When WP_hole "is in the open state, control is performed to perform recording prohibition regardless of the state of the recording control information B1, B2, B3, and" WP_hole "is closed or an optical disc without a cartridge is provided. ), Control to perform recording prohibition or recording permission according to the state of the recording control information (B1, B2, B3). That is, recording control is performed by selecting any one of the first to fourth embodiments of the present invention, and recording and reproducing of a specific area is performed according to the selected control method.

Accordingly, the recording is performed in the region where recording is allowed, and when the user wants to record in the region where the recording is prohibited, the user is provided to the corresponding region through the display device 30 of FIG. It is possible to inform that the record is prohibited.

In addition, the control unit 12 is an element for controlling the operation of the entire optical recording and reproducing apparatus, and receives a user command through an interface with the user, and transmits it to the microcomputer 16 in the recording and reproducing unit 20. It performs a role of controlling the operation to be performed as it is. In particular, by utilizing the result of the recording control information transmitted from the microcomputer 16, the recording control for the entire disk area or some specific area is performed.

However, the control unit 12 is not provided in the optical recording and reproducing apparatus, and may be composed of only the recording and reproducing unit 20 (also referred to as “drive” in particular). In this case, the microcomputer 16 controls the control unit 12. It is obvious that it can play the role of).

In this regard, the AV decoder 17 finally decodes the output data under the control of the controller 12 and provides the same to the user. The AV encoder 18 controls the controller 12 to perform a function of recording a signal on the optical disc. The input signal is converted into a signal of a specific format, for example, MPEG2 (MPEG2) transport stream, and provided to the signal processing section 13 in the recording / reproducing section according to the control.

As described above, preferred embodiments of the present invention are disclosed for purposes of illustration, and those skilled in the art can improve various other embodiments within the spirit and technical scope of the present invention disclosed in the appended claims below.
