  Further, as the content of the reproduction control flag PCF, specifically, the content of the actual information D to be reproduced based on the reproduction list PL including the reproduction control flag PCF is, for example, for a person other than a specific user Is set to "1" when playback control is to be performed such as prohibiting playback, and the playback control flag PCF is set to "0" when playback control is not to be performed.

  Further, as the contents of the playlist display prohibition flag PHF, specifically, whether the display of the playlist PL itself including the playlist display prohibition flag PHF should be prohibited on the menu screen described later. That is, when the display of the representative image corresponding to the reproduction list PL is to be prohibited on the menu screen, the reproduction control flag PCF is “1”, and the display of the representative image is not prohibited. The reproduction list display prohibition flag PHF is set to “0”.

  Next, as the attribute information group CIS, attribute information CI1, CI2, CI3,..., CIn, which is attribute information corresponding to each real information and indicates the attribute (type) for each real information, is the same number as the real information. Only minutes are recorded. At this time, specifically, as the attribute, for example, the genre name to which the content of the corresponding actual information belongs, the recording date and time of the actual information, whether the actual information is text information, image information, or audio information, etc. Is recorded as attribute information.

  Finally, as the actual information group DS, one or a plurality of actual information D1, D2, D3,..., Dn as information to be actually reproduced is recorded together with identification information that can be distinguished from each other. At this time, as the actual information, for example, one movie and one musical piece are recorded as one actual information D, respectively.

(B) Configuration and Operation of Information Recording / Reproducing Device Next, the configuration and operation of the information recording / reproducing device according to the first embodiment for recording / reproducing the real information D using the recording format shown in FIG. This will be described with reference to FIGS.

  First, the configuration and overall operation of the information recording / reproducing apparatus will be described with reference to FIG. FIG. 2 is a block diagram showing a schematic configuration of the information recording / reproducing apparatus.

  As shown in FIG. 2, the information recording / reproducing apparatus S of the first embodiment includes a pickup 2 as detection means, an A / D (analog / digital) converter 3, an MPEG (Moving Picture Coding Expert Group) encoder 4, Multiplexers 5 and 10, recording encoder 6, recording circuit 7, reproduction circuit 8, reproduction decoder 9, MPEG decoder 11, menu screen generation circuit 12, D / A converter 13, and still image encoder 14 A buffer 15, a spindle motor 16, a reproduction information recording unit, a control information recording unit, a CPU 17 as a limiting unit and a prohibiting unit, a servo circuit 18, a display unit 19, an operation unit 20, a switch 22, It is comprised by.

  Further, as shown in FIG. 3, the menu screen generation circuit 12 includes a capture unit 23, a scale change unit 24, a memory 25, a GUI (Graphical Users Interface) screen generation unit 26, and a synthesis unit 27. Has been.

  Next, an outline operation of each component will be described with reference to FIGS.

  First, a case where information to be recorded from outside (specifically, the information to be recorded includes both image information and audio information) will be described.

  When an information signal Sin corresponding to the information to be recorded is input from the outside and a recording button (not shown) is operated in the operation unit 20, first, the A / D converter 3 digitizes the information signal Sin to obtain a digital signal. Sd is generated and output to the MPEG encoder 4.

Based on the control signal S ₇ output from the CPU 17, the MPEG encoder 4 compresses the input digital signal Sd using the MPEG2 method, generates a compressed signal Se, and outputs the compressed signal Se to the multiplexers 5 and 10.

Then, the multiplexer 5 switches the input compression signal Se and a buffer signal Sbo described later as necessary based on the control signal S ₅ output from the CPU 17 to generate a switching recording signal Smr. Output to the recording encoder 6.

The recording encoder 6 converts the format of the switching recording signal Smr into the recording format shown in FIG. 1 with respect to the input switching recording signal Smr based on the control signal S ₃ output from the CPU 17. A formatting process is performed, and a recording encoding signal Sre is generated and output to the recording circuit 7.

At this time, specifically, as the formatting process, first, based on the control signal S ₃ , the input switching recording signal Smr is output to the CPU 17 as it is if necessary. Based on the switching recording signal Smr, the CPU 17 stores the general information GM, menu control information MC, menu still image data group MD, mark control information KC, mark still image data group KD, and each reproduction list PL. including playlist information group PLS, an attribute information group CIS, generates real information group DS, and other information ET, and outputs to the recording encoder 6 as the control signal S _3. Thereby, the recording encoder 6 generates the recording encoded signal Sre in accordance with the recording format shown in FIG. Note that information for generating the virtual playlist VPL, that is, identification information indicating a part of each real information D to be included in the virtual playlist VPL, information indicating a playback order of the part, etc. It is input from the operation unit 20 in the formatting process.

Next, the recording circuit 7 converts the input recording encode signal Sre into a recording signal Sr for recording based on the control signal S ₂ output from the CPU 17, and outputs it to the pickup 2. At this time, in the recording circuit 7, so-called write strategy processing or the like is performed on the recording encode signal Sre in order to form on the optical disc 1 a pit having a shape that exactly corresponds to the information to be recorded.

  Thereafter, on the basis of the recording signal Sr output from the recording circuit 7, the pickup 2 drives a light source such as a semiconductor laser (not shown) in the pickup 2 to generate a light beam B such as a laser beam to generate an optical disc 1 The recording signal Sr is recorded on the optical disc 1 by forming a pit corresponding to the recording signal Sr. At this time, the optical disk 1 is rotated at a predetermined rotational speed by a spindle motor 16 driven based on a spindle control signal Ssm described later. On the optical disc 1, for example, pits corresponding to the recording signal Sr are formed by the phase change method, and the recording signal Sr is recorded.

  On the other hand, the compressed signal Se output to the multiplexer 10 passes through the multiplexer 10 and is output to the MPEG decoder 11 as a reproduction switching signal Smp.

Based on the control signal S ₉ output from the CPU 17, the MPEG decoder 11 decompresses the input reproduction switching signal Smp (the compressed signal Se itself when recording information) by the MPEG2 method. Processing is performed, and the decoded signal Sdc is output to one input terminal of the menu screen generating circuit 12, the still image encoder 14, and the switch 22.

Next, based on the control signal S ₁₁ output from the CPU 17, the still image encoder 14 uses the image information included in the input decode signal Sdc as a representative image in the menu screen M by processing to be described later. The selected image is encoded as a still image and is output to the buffer 15 as a still image encoding signal Sse.

Thus, the buffer 15, based on the control signal S ₈ which is output from the CPU 17, the read temporarily stores the still image encoded signal Sse, and outputs to the multiplexer 5 as the buffer signal Sbo.

On the other hand, at the time of information recording, the switch 22 is switched to the decode signal Sdc side based on the control signal S ₁₃ output from the CPU 17.

  The decode signal Sdc is output from the switch 22 to the D / A converter 13 as a switching signal Sch.

  Next, the D / A converter 13 converts the switching signal Sch into an analog signal, generates an output signal Sout corresponding to the information signal Sin, and outputs the output signal Sout to an external monitor (not shown) or a speaker (not shown).

At this time, when the CPU 17 recognizes that a recording button (not shown) in the operation unit 20 has been operated based on the instruction signal Sc from the operation unit 20, the control signals S ₂ , S ₃ , S ₅ , S _7. , S ₈ , S _11, and S ₁₃ are generated and output to the above-described constituent members to control each operation for recording described above.

  With the above-described series of information recording operations, an image or sound corresponding to the currently recorded recording signal Sr can be recorded while monitoring in real time. During this information recording, the menu screen generation circuit 12 does not operate.

  Next, an operation for reproducing information recorded on the optical disc 1 will be described.

  At the time of reproduction, first, when a reproduction button (not shown) is operated on the operation unit 20, the pickup 2 irradiates the rotating optical disk 1 with a reproduction light beam B, and is formed on the optical disk 1 based on the reflected light. A detection signal Sp corresponding to the pit being generated is generated and output to the reproduction circuit 8.

Next, the reproduction circuit 8 amplifies the output detection signal Sp with a predetermined amplification factor based on the control signal S ₁ output from the CPU 17 and shapes the waveform thereof to generate the reproduction signal Spp. Output to the playback decoder 9.

The reproduction decoder 9 performs an unformatting process corresponding to the formatting process in the recording encoder 6 on the inputted reproduction signal Spp based on the control signal S ₄ outputted from the CPU 17 to reproduce the reproduction decoded signal Spd. Is output to the multiplexer 10.

Then, the multiplexer 10, based on a control signal S ₆ which is output from the CPU 17, passed through the reproduction decode signal Spd coming, and outputs the MPEG decoder 11 as the reproduction changeover signal Smp.

Based on the control signal S ₉ output from the CPU 17, the MPEG decoder 11 performs the above-described expansion processing on the input reproduction switching signal Smp, generates the decode signal Sdc, and generates a menu screen generation circuit. 12 and one input terminal of the switch 22.

Thus, the menu screen generating circuit 12, using an image that is specified based on the control signal S ₁₂ that is output from the CPU 17, from the decoded signal Sdc coming input by the control signal S _12, the information reproducing Sometimes a menu screen (including the above-described representative image) for selecting which reproduction information PL should be reproduced based on which reproduction list PL is generated and output to the other input terminal of the switch 22 as the menu signal Smy. To do.

Then, the switch 22 based on the control signal S ₁₃ that is output from the CPU 17, switches between menus signal Smy and the decoded signal Sdc coming, and outputs to the D / A converter 13 as the switching signal Sch.

  As a result, the D / A converter 13 converts the switching signal Sch into an analog signal, generates an output signal Sout including either the information signal Sin or the menu signal corresponding to the menu signal Smy, and outputs an external monitor or illustration to be described later. Output to a speaker that does not.

At this time, when the CPU 17 recognizes that a playback button (not shown) in the operation unit 20 has been operated based on the instruction signal Sc from the operation unit 20, the control signals S ₁ , S ₄ , S ₆ , S _{9 are described.} , S ₁₂ and S ₁₃ are generated and output to the above-described constituent members to control the above-described operations for reproduction.

  In parallel with these information recording or information reproduction operations, the CPU 17 generates a control signal Ss for servo-controlling the spindle motor 16 and the pickup 2 and outputs the control signal Ss to the servo circuit 18. Based on the control signal Ss, the spindle control signal Ssm for controlling the rotation of the spindle motor 16 is generated and output to the spindle motor 16, and pickup control for so-called tracking servo control and focus servo control in the pickup 2 is performed. A signal Ssp is generated and output to the pickup 2. The pickup 2 records the recording signal Sr or detects the detection signal Sp while performing tracking servo control and focus servo control on the light beam B based on the pickup control signal Ssp.

  Information necessary for the user to control the operation of the information recording / reproducing apparatus S described above is displayed on the display unit 19 based on the display signal Sdp from the CPU 17.

  Next, the operation of each component in the menu screen generation circuit 12 during the information reproduction will be described with reference to FIG.

As shown in FIG. 3, the capture unit 23 in the menu screen generation circuit 12 receives an input decode signal Sdc based on a control signal S ₁₄ included in the control signal S ₁₂ output from the CPU 17. Among them, a signal corresponding to the representative image used for constructing the menu screen is temporarily stored and output to the scale changing unit 24 as a capture signal Scp.

  Then, the scale changing unit 24 changes the image included in the capture signal Scp to a scale necessary for constructing the menu screen, and outputs it to the memory 25 as the scale signal Sex.

  Thereafter, the memory 25 temporarily stores the scale signal Sex and outputs the scale signal Sex to the combining unit 27.

On the other hand, GUI screen generation unit 26 based on the control signal S ₁₅ contained in the control signal S _12, necessary for constituting the menu screen other than the image contained in the scale signal Sex image (so-called icons ) And output to the synthesizer 27 as an image signal Sg.

Then, the composition unit 27 based on the control signal S ₁₆ contained in the control signal S _12, generates a menu screen by using the scale signal Sex, image signal Sg, and decoded signal Sdc, as the menu signal Smy Output to the switch 22.

  Next, a specific operation when the information recording / reproducing apparatus S having the above-described configuration records the actual information D or the like on the optical disc 1 in accordance with the recording format shown in FIG. 1 will be described with reference to FIG. FIG. 4 is a flowchart showing the recording process of the real information D according to the first embodiment, which is mainly executed mainly by the CPU 17.

  In the recording process, first, it is confirmed whether or not the start of the recording process is instructed by a recording button (not shown) in the operation unit 20 (step S1), and when the start of the recording process is not instructed (step S1; NO) Next, in the operation unit 20, it is confirmed whether or not an unillustrated end button (specifically, a power off button or the like) indicating the end of the recording process has been operated (step S13). When the end button is operated (step S13; YES), the recording process according to the first embodiment is terminated as it is. On the other hand, when the end button is not operated (step S13; NO), step S1 is performed as it is. Go back and wait.

  On the other hand, when the start of recording is instructed (step S1; YES), the actual information D input as the information signal Sin is recorded on the optical disc 1 (step S2). Then, it is confirmed whether or not the recording of all the real information D has been completed (step S3). If not completed (step S3; NO), the recording process is continued (step S2). Step S3; YES) Next, the attribute information CI corresponding to each recorded actual information D is created, and the corresponding playlist PL is similarly created. The created attribute information CI and playlist PL are created. Recording is performed on the optical disc 1 in accordance with the recording format shown in FIG. 1 (step S4).

  Next, whether or not the content of the real information D reproduced based on the generated reproduction list PL should be subjected to reproduction control such as prohibition of reproduction for a non-specific user is operated. If it is confirmed based on the operation content in the unit 20 (step S5) and the content is not the content to be played back (step S5; NO), the recording process according to the first embodiment is terminated as it is, while the playback control is performed. If it is the content to be performed (step S5; YES), whether or not the personal identification number PIN is already recorded in the general information GM of the optical disc 1 in which the real information D and the reproduction list PL are recorded (steps S2 and S4). Is confirmed by searching the general information GM (step S6). If the password PIN is not recorded (step S6; NO), a display indicating that the password PIN should be newly entered is performed on a display (not shown) to prompt the input process. When a new password PIN is input corresponding to (step S7), the input password PIN is recorded in the area shown in FIG. 1 in the general information GM (step S8) and subsequent steps. The process proceeds to S9.

  On the other hand, if the PIN PIN has already been recorded in the determination in step S6 (step S6; YES), then the display of the created playlist PL itself is prohibited on the menu screen (step S4). Whether or not the display of the representative image corresponding to the playlist PL is to be prohibited on the menu screen is confirmed based on the operation content in the operation unit 20 (step S9). ) When the display of the representative image is not to be prohibited (step S9; NO), the content of the reproduction control flag PCF to be included in the corresponding reproduction list PL based on the determination in step S5 is “1”. "And the content of the playlist display prohibition flag PHF to be included in the same manner is set to" 0 "(step 12).

  On the other hand, when the display of the representative image is to be prohibited (step S9; YES), the content of the reproduction control flag PCF to be included in the corresponding reproduction list PL based on the determination in step S5 is “ “1” and the content of the reproduction list display prohibition flag PHF to be included are set to “1” (step S10).

  Then, the contents of the corresponding reproduction list PL recorded at the time when the setting of the contents of the reproduction control flag PCF and the contents of the reproduction list display prohibition flag PHF is completed (steps S10 and S12) (step S4) are rewritten (step S4). S11), a series of recording processing ends.

  Next, a specific operation of editing processing of the real information D and the like executed by the information recording / reproducing apparatus S having the above-described configuration in accordance with the recording format shown in FIG. 1 will be described with reference to FIG. FIG. 5 is a flowchart showing the editing process of the real information D according to the first embodiment, which is mainly executed mainly by the CPU 17. Specifically, as the editing process, a process for creating a new virtual playlist VPL, a process for additionally recording new real information D, a process for changing the contents of an existing virtual playlist VPL, or existing real information A process of erasing a part of D from the optical disk 1 is included.

  In the editing process, first, a representative image corresponding to each playlist PL recorded on the optical disc 1 is displayed on a display (not shown) while being subjected to a control process such as display prohibition by a process described in detail later. In step S40), the reproduction list PL to be edited is selected by selecting a desired one of the displayed representative images (step S41).

  When the playlist PL is selected, whether or not the actual information D corresponding to the selected playlist PL is to be subjected to the above-described playback control is next determined in the selected playlist PL. This is determined by confirming the content of the reproduction control flag PCF (step S42). When the playback control is not to be performed (step S42; NO), the process proceeds to step S46 to be described later. On the other hand, when the playback list PL is to be playback controlled (step S42; YES), Next, whether or not the representative image corresponding to the playlist PL is prohibited from being displayed on the menu screen is determined by confirming the contents of the playlist display prohibition flag PHF in the selected playlist PL. (Step S43). Then, in order to cancel the prohibition of display, a display indicating that the personal identification number PIN that should have been recorded on the optical disc 1 should be input on a display (not shown) or the like to prompt the input processing. When a new PIN number is entered (step S44), the entered PIN number is checked against the PIN number recorded in the general information GM, and whether or not they match. (Step S45). As a result, when the two do not match (step S45; NO), it is determined that the user who should not see the representative image is currently performing the editing process, and the process returns to step S41 to select a different playlist PL. Let it be done. On the other hand, when the entered personal identification number PIN matches the recorded personal identification number PIN (step S45; YES), a desired editing process is executed while displaying the selected reproduction list PL. (Step S46).

  Next, it is confirmed whether or not an operation for completing the editing process has been executed in the operation unit 20 (step S47). When the operation has not been completed (step S47; NO), the editing process is continued as it is. When the operation has been completed (step S47; YES), whether or not the content of the actual information D to be reproduced based on the edited reproduction list PL is to be reproduced is determined in the operation unit 20. If it is determined based on the operation content (step S48) and playback control is not to be performed (step S48; NO), the playback control flag PCF in the newly created playback list PL is set to “0” and the playback list. The display prohibition flag PHF is set to “0” (step S49), and the process proceeds to step S56 described later.

  On the other hand, when the content of the actual information D to be reproduced based on the edited reproduction list PL is to be reproduced (step S48; YES), the edited reproduction list PL is then recorded. (Step S46) Whether the PIN number PIN has already been recorded in the general information GM of the optical disc 1 is confirmed by searching the general information GM (Step S50). If the password PIN is not recorded (step S50; NO), a display indicating that the password PIN should be newly input is performed on a display (not shown) to prompt the input process. When a new password PIN is input corresponding to (step S51), the input password PIN is recorded in the area shown in FIG. 1 in the general information GM (step S52) and subsequent steps. The process proceeds to S53.

  On the other hand, if the PIN PIN has already been recorded in the determination in step S50 (step S50; YES), the display of the representative image corresponding to the created reproduction list PL is then displayed on the menu screen (step S46). Is confirmed based on the operation content in the operation unit 20 (step S53), and when the display of the representative image is not to be prohibited (step S53; NO), the above Based on the determination in step S48, the content of the reproduction control flag PCF to be included in the corresponding reproduction list PL is set to “1” and the content of the reproduction list display prohibition flag PHF to be included is also set to “0”. (Step S55).

  On the other hand, when the display of the representative image is to be prohibited (step S53; YES), the content of the reproduction control flag PCF to be included in the corresponding reproduction list PL based on the determination in step S48 is “ “1” is set, and the content of the reproduction list display prohibition flag PHF to be included is set to “1” (step S54).

  Then, the contents of the corresponding reproduction list PL recorded at the time of completion of the setting of the contents of the reproduction control flag PCF and the contents of the reproduction list display prohibition flag PHF (steps S49, S54 and S55) are rewritten. (Step S56), a series of editing processing is terminated.

  Next, details of the display processing (step S40) of the representative image corresponding to the reproduction list PL in the editing processing described above will be described with reference to FIGS. FIG. 6 is a flowchart showing a playlist display process according to the first embodiment, and FIG. 7 is a diagram showing a playlist display example according to the first embodiment.

  As shown in FIG. 6, in the representative image display process in step S40, first, the optical disc 1 is inserted into the insertion slot of the optical disc 1 (not shown) in the information recording / reproducing apparatus S (step S15). All the reproduction lists PL recorded on the optical disc 1 are detected (step S16).

  Then, for each of the detected playlists PL, it is determined whether or not the corresponding representative image is prohibited from being displayed on the menu screen by checking the contents of the playlist display prohibition flag PHF in each playlist PL. (Step S17).

  If the representative image is not prohibited from being displayed (step S17; NO), the corresponding representative image is displayed as indicated by the symbol SI in the menu screen M shown in FIG. 7A, for example, and if necessary. Then, the reproduction list information such as the name of the reproduction list PL or the creation date and time is displayed by searching the reproduction list PL (step S19), and the process proceeds to step S20.

  On the other hand, if it is determined in step S17 that the corresponding representative image is prohibited from being displayed (step S17; YES), the corresponding representative image is displayed as a non-display image SSI in the menu screen M of FIG. In such a manner, the contents as the representative image are displayed so that they cannot be recognized, and the reproduction list information is not displayed (step S18).

  Then, it is confirmed whether or not the display processing has been completed up to the representative image corresponding to the last playlist PL (step S20). If not, the display processing is returned to step S16 and again described above. The process is repeated. On the other hand, when the display of the representative images corresponding to all the reproduction lists PL is completed (step S20; NO), the process proceeds to step S41 as it is.

  In the display process shown in FIG. 6, the representative image that is prohibited from being displayed is displayed instead of the non-display image SSI shown in FIG. 7A. For the playlist PL for which display of the corresponding representative image is prohibited, as shown in FIG. 8, no image is displayed at the corresponding position (see FIG. 9A), and the display is permitted. Only the image SI may be displayed (step S19). At this time, as shown in FIG. 9A, a representative image (playback list PL) whose display is prohibited together with the representative image SI whose display is permitted exists in a part of the menu screen M. It is good also as displaying the suggestion icon IC which suggests.

  Next, details of the selection process (step S41) of the reproduction list PL in the editing process described above will be described with reference to FIG. FIG. 10 is a flowchart showing the playlist selection processing in the first embodiment.

  As shown in FIG. 10, in the selection process of the playlist PL in step S41, first, when the menu screen M shown in FIG. 7 is displayed by the process of step S40, next, in the menu screen M A process for selecting the playlist PL is executed in the operation unit 20 (step S25). Next, it is determined whether or not the selected playlist is a playlist PL for which the corresponding representative image is prohibited from being displayed. Determination is made (step S26).

  When the playlist PL for which the display of the representative image SI is not prohibited is selected (step S26; NO), the process directly proceeds to the step S42, while the playlist for which the display of the representative image SI is prohibited. If PL is selected (step S26; YES), then, to cancel the prohibition of the display, as shown in FIG. 7B, the personal identification number PIN that should be recorded on the optical disc 1 is input. When the input field PT indicating that it should be displayed is displayed on the menu screen M to prompt the input process and the personal identification number PIN is input correspondingly (step S27), the input personal identification number The number PIN and the personal identification number PIN recorded in the general information GM are collated, and it is confirmed whether or not they match (step S28). As a result, when the two do not match (step S28; NO), it is determined that the user who should not see the representative image SI is currently performing the editing process, and the process returns to step S25 to select a different playlist PL. To do. On the other hand, when the entered personal identification number PIN matches the recorded personal identification number PIN (step S28; YES), a corresponding representative image SI is newly displayed in the menu screen M as shown in FIG. In addition, the playlist information such as the name of the playlist PL itself or the date and time of creation is displayed by searching the playlist PL (step S29) as necessary, and the process proceeds to step S42.

  Note that, in the above-described selection process of the playlist PL, when the representative image SI that is prohibited from being displayed as shown in FIG. 8 is not displayed at all (step S40), it is suggested as shown in FIG. 9A. When the icon IC is displayed and the suggestion icon IC is selected in this state (step S25), the entry field PT is displayed in the menu as shown in FIG. Displaying on the screen M prompts the input process of the password PIN, and correspondingly, the password PIN is input (step S27), which matches the password PIN recorded in the general information GM. When (step S28; YES), as shown in FIG. 9C, the corresponding representative image SI is newly displayed in the menu screen M and the suggestion icon IC is displayed in the menu. Erasing from the surface M, and displaying the playlist information such as the name of the playlist PL itself or the date and time of creation as needed by searching the playlist PL (step S29), and proceeding to step S42. To do.

  Finally, with reference to FIG. 11, a specific operation of the reproduction process from the optical disc 1 for the actual information D and the like executed by the information recording / reproducing apparatus S having the above-described configuration in accordance with the recording format shown in FIG. explain. FIG. 11 is a flowchart showing a reproduction process of the real information D according to the first embodiment, which is mainly executed with the CPU 17 as the center.

  As shown in FIG. 11, as the reproduction process, firstly, the reproduction list PL display process (step S60) and the selection process (step S61) similar to the editing process shown in FIG. 5 are executed.

  When the display process and selection process of the playlist PL having the contents to be reproduced are completed, whether the contents of the actual information D reproduced based on the selected playlist PL should be subjected to reproduction control next. No is determined by confirming the content of the reproduction control flag PCF in the selected reproduction list PL (step S62). If the reproduction control is not to be performed (step S62; NO), the selection is performed as it is. The corresponding real information D is reproduced from the optical disc 1 based on the contents of the reproduced reproduction list PL (step S66), and it is further confirmed whether or not the reproduction up to the last real information D to be reproduced is completed (step S66). S67).

  When the reproduction process up to the last reproduction list PL is not completed (step S67; NO), the process returns to step S60 to select the reproduction list PL including the actual information D to be reproduced next. On the other hand, when the reproduction process is completed up to the last reproduction list PL to be reproduced (step S67; YES), the reproduction process of the first embodiment is terminated as it is.

  On the other hand, if it is determined in step S62 that the content of the selected reproduction list PL is the content to be reproduced (step S62; YES), the representative image corresponding to the selected reproduction list PL is the next. It is determined whether or not the reproduction list PL is prohibited from being displayed (step S63).

  If the representative image is the playlist PL whose display is not prohibited (step S63; NO), the process proceeds to step S66 as it is, while the representative image is the playlist PL whose display is prohibited. (Step S63; YES), next, in order to cancel the prohibition of display, for example, as shown in FIG. 7B, it is to be inputted the password PIN that should be recorded on the optical disc 1. When an input field PT is displayed on the menu screen M to prompt the input process and the password PIN is input correspondingly (step S64), the input password PIN and the general information GM are input. The personal identification number PIN recorded in the password is collated, and it is confirmed whether or not they match (step S65). As a result, if the two do not match (step S65; NO), it is determined that the user who should not see the representative image is currently performing the editing process and returns to step S60 to select a different playlist PL. Let it be done. On the other hand, when the entered personal identification number PIN matches the recorded personal identification number PIN (step S65; YES), in order to reproduce the actual information D corresponding to the contents of the reproduction list PL, the above steps S66 and S67 are performed. The reproduction process according to the first embodiment is terminated.

  As described above, according to the operation of the information recording / reproducing apparatus S of the first embodiment, the display of the reproduction list PL is restricted (restricted) based on the recorded reproduction list display prohibition flag PHF. The display of the representative image can be controlled according to the content of the information, so that the content of the actual information D corresponding to the playlist PL is inadvertently recognized by the user when the representative image is inadvertently presented to the user. Can be prevented.

  Further, since the representative image is displayed prior to the start of the reproduction process of the real information D corresponding to the reproduction list PL, the display of the representative image is limited based on the recorded reproduction list display prohibition flag PHF. Thus, the display of the representative image prior to the reproduction process of the real information D corresponding to the reproduction list PL can be controlled.
