Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a disc recording / reproducing apparatus, a disc information registration method, and a recording medium that can easily register disc information on an MD (mini disc) or the like on which an arbitrary musical piece is recorded.
[0002]
[Prior art]
With the widespread use of music CDs (compact discs), MDs (minidiscs), etc., disc playback devices represented by MD players are becoming popular as one of popular music playback devices. This disc playback apparatus manages a plurality of music pieces recorded on an MD or the like by track numbers determined in correspondence with the respective music pieces. Various playbacks can be performed using this track number.
For example, the disc playback apparatus can play back the music corresponding to the track number selected by the user in the order selected by the program playback function. In addition, the random playback function can sequentially play the music of the track number selected by the random number.
[0003]
There is also known a disc recording / reproducing apparatus capable of recording an arbitrary musical piece on the MD when a recordable MD (MD-MO; MD Magnet Optical, etc.) is stored as a recording medium. This disc recording / playback apparatus can record a plurality of music data in the program area of the MD, and can record the disc title and the track title for each track number in the U-TOC (User's Table Of Contents) of the MD. Disk information can be registered.
For example, the disc recording / reproducing apparatus records music data acquired via a predetermined audio input terminal in a program area of the MD in accordance with a recording instruction from the user. Further, the disc information including the disc title and the track title input from the user is acquired via a predetermined operation unit, and the acquired disc information is registered in the U-TOC of the MD.
Then, the disc recording / reproducing apparatus displays the disc information registered in the U-TOC on a predetermined display unit at the time of reproducing the music data recorded on the MD.
[0004]
On the other hand, a CD text standard has been established as a new standard for CDs, and CD text discs conforming to the CD text standard are becoming widespread. This CD text disc is a CD in which detailed text data such as a songwriter, a composer, and a message as well as a disc title and an artist name of each song are recorded in advance.
Such a CD text disc is reproduced by a disc reproducing apparatus such as a CD player corresponding to the CD text standard. In this case, when a CD text disc is loaded, the disc playback device reads the recorded text data and displays it on a predetermined display unit.
[0005]
In some cases, the user may handle such a CD text disc by playing it on a disc playback device and recording the played music on an MD using a disc recording / playback device connected via a predetermined cable.
For example, a user who owns a stationary disk playback device and a portable disk recording / playback device can play music recorded on a CD text disk on an MD so that the music recorded on the CD text disk can be enjoyed outdoors. For example, when dubbing. In this case, the disc recording / reproducing apparatus can acquire the music data reproduced by the disc reproducing apparatus and record the acquired music data in the program area of the MD.
[0006]
[Problems to be solved by the invention]
When dubbing the music on the CD text disc described above to the MD, generally, the disc recording / playback apparatus cannot acquire the text data recorded on the CD text disc, so the user can register disc information in the MD. It was necessary to input all characters for each character.
That is, the user needs to input all characters of the disc title, track title, and the like via a predetermined operation unit of the disc recording / reproducing apparatus, and register the disc information, which is very complicated.
[0007]
In order to eliminate such complications, the text data recorded on the CD text disc can be acquired by the disc recording / playback device, and when the necessary text data is acquired by the disc recording / playback device, the acquired text is recorded. It is also conceivable to register data in the MD unconditionally as disk information.
[0008]
However, in this case, since the contents of the disk information registered in the MD are fixedly determined, the degree of freedom is lost. Therefore, when registering disc information according to the user's preference, for example, when adding a subtitle to the disc title, it is necessary to input all the necessary subtitles etc. and input the disc information to update the disc information. It was still complicated for the person.
[0009]
Even if a part of the acquired text data can be registered in the MD as disc information, a normal CD on which no text data is recorded is played back on the disc playback device, and the played music is recorded in the MD. In this case, the disc recording / reproducing apparatus cannot naturally acquire the text data. Therefore, it is necessary for the user to input all characters of the disc title, track title, and the like and register the disc information through a predetermined operation unit, which is complicated.
[0010]
The present invention has been made in view of the above circumstances, and an object thereof is to provide a disk recording / reproducing apparatus, a disk information registration method, and a recording medium that can easily register disk information in an MD or the like.

[0049]
The operation of the disc recording / reproducing apparatus 1 according to the embodiment of the present invention will be described below with reference to the drawings.
First, a table update process for updating the artist table 91 and the message table 92 stored in the memory 109 of the disc recording / reproducing apparatus 1 will be described. FIG. 5 is a flowchart for explaining a table update process performed by the disk recording / playback apparatus 1 and a data transmission process performed by the disk playback apparatus 2. The table update process and data transmission process shown in FIG. 5 are started after the MD 10 is loaded in the disk recording / playback apparatus 1 and a CD text disk or the like is loaded in the disk playback apparatus 2.
[0050]
First, the process control unit 101 of the disc recording / reproducing apparatus 1 determines whether or not the data sent from the disc reproducing apparatus 2 can be received (step S11). That is, the processing control unit 101 determines whether or not the communication line 3 and the digital data line 4 are connected to the processing control unit 101 and the communication line 3 and the like are also connected to the disc reproducing apparatus 2.
[0051]
If the process control unit 101 determines that data reception is not possible, the process control unit 101 ends the table update process. On the other hand, if it is determined that the data can be received, the processing control unit 101 requests the disc playback apparatus 2 to transmit the text data (step S12). That is, the processing control unit 101 transmits predetermined information for requesting transmission of text data to the disc playback apparatus 2 via the communication line 3.
[0052]
On the other hand, the process control unit 201 of the disc playback apparatus 2 determines whether or not the text data transmission request information has been acquired (step S21).
[0053]
If the process control unit 201 determines that the transmission request information has not been acquired, the process control unit 201 ends the data transmission process. On the other hand, when determining that the transmission request information has been acquired, the processing control unit 201 determines whether or not the reproduction target CD is a CD text disc (step S22).
[0054]
If the processing control unit 201 determines that the disc is not a CD text disc, the processing control unit 201 generates predetermined reply data indicating that the disc is a normal CD (step S23). On the other hand, when it is determined that the reproduction target CD is a CD text disc, the process control unit 201 reads the recorded text data (step S24).
[0055]
The process control unit 201 transmits either the reply data generated in step S23 or the text data read in step S24 to the disc recording / reproducing apparatus 1 via the communication line 3 (step S25). After transmitting the data, the process control unit 201 ends the data transmission process.
[0056]
On the disc recording / reproducing apparatus 1 side, the processing control unit 101 receives the data sent from the disc reproducing apparatus 2 (step S13).
[0057]
The process control unit 101 determines whether the received data is text data (step S14).
[0058]
If the process control unit 101 determines that the data is not text data, the table update process ends. On the other hand, when determining that the received data is text data, the process control unit 101 determines whether or not the same data has been stored in the memory 109 (step S15). That is, the process control unit 101 determines whether or not the artist table 91 and the message table 92 stored in the memory 109 have corresponding data included in the received text data.
[0059]
If the process control unit 101 determines that the same data has been stored, the process control unit 101 ends the table update process. On the other hand, if it is determined that the same data is not stored, the processing control unit 101 updates the artist table 91 and the message table 92, respectively (step S16).
That is, the process control unit 101 adds the artist name included in the text data acquired from the disc playback apparatus 2 to the artist table 91, and adds the message included in the text data to the message table 92, and the contents after the addition. The artist table 91 and the like are stored in the memory 109. Note that when the artist table 91 is updated, the process control unit 101 sorts the artist names in ascending order and then stores them in the memory 109.
[0060]
As described above, the artist table 91 and the message table 92 are sequentially updated with the text data acquired from the disc playback apparatus 2. The updated artist table 91 is used when the user selects an artist name in a data input process described later. The message table 92 is used when selecting a message to be added to a disc title or the like in data editing processing described later.
[0061]
Next, a disc information registration process for registering a disc title or the like input by the user will be described. FIG. 6 is a flowchart for explaining the disc information registration process performed by the disc recording / reproducing apparatus 1.
The disc information registration process shown in FIG. 6 is started after the disc recording / playback apparatus 1 records the music data acquired from the disc playback apparatus 2 in the MD 10.
[0062]
First, the process control unit 101 determines whether or not the current operation mode is the disc information registration mode (step S31). That is, the processing control unit 101 determines whether or not the operation mode is the disc information registration mode when the instruction information for instructing the disc information registration is input from the user via the key input unit 107. .
[0063]
If the process control unit 101 determines that the operation mode is not the disk information registration mode, the process control unit 101 ends the disk information registration process without performing any particular processing. On the other hand, if it is determined that the disc information registration mode is set, the process control unit 101 determines whether or not text data has been acquired in the table update process described above (step S32). That is, the processing control unit 101 determines whether or not the recording medium reproduced by the disc reproducing apparatus 2 is a CD text disc.
[0064]
If the process control unit 101 determines that the text data has not been acquired in the table update process, the process control unit 101 executes a data input process (step S33). On the other hand, when determining that the text data is acquired, the process control unit 101 executes a data editing process (step S34).
[0065]
Hereinafter, these data input processing and data editing processing will be described with reference to the drawings. FIG. 7 is a flowchart for explaining the data input process, and FIG. 8 is a flowchart for explaining the data editing process.
[0066]
First, the data input process shown in FIG. 7 will be described.
The process control unit 101 acquires a disc title input from the user for each character (step S41). That is, the processing control unit 101 displays a predetermined message for prompting input of a disc title on the display unit 108 and acquires a disc title input for each character from the user via the key input unit 107. .
[0067]
The process control unit 101 determines whether or not the input of the disc title by the user is completed (step S42). That is, the process control unit 101 determines whether or not the instruction information indicating the completion of inputting the disc title has been input by the user via the key input unit 107.
[0068]
If the process control unit 101 determines that the input of the disc title has not ended, the process control unit 101 returns the process to step S41 and repeatedly executes the processes of steps S41 and S42 described above. On the other hand, if it is determined that the input of the disc title has been completed, the process control unit 101 registers the acquired disc title in the U-TOC 11 in the MD 10 and then determines whether or not an artist name has been input ( Step S43). That is, the processing control unit 101 displays a predetermined message for confirming whether or not an artist name has been input on the display unit 108 and acquires instruction information input from the user via the key input unit 107.
[0069]
If the process control unit 101 determines that no artist name has been input, the data input process ends. On the other hand, if it is determined that an artist name has been input, the processing control unit 101 sequentially displays the contents of the artist table 91 stored in the memory 109 (step S44). That is, the process control unit 101 displays the artist names and the like of the artist table 91 sorted in ascending order on the display unit 108. At that time, the processing control unit 101 displays the selection number on the display unit 108 so that the user can specify the artist name to be selected.
[0070]
The process control unit 101 determines whether an artist name has been selected (step S45). That is, the process control unit 101 determines whether or not a selection number corresponding to any artist name displayed on the display unit 108 is input from the user via the key input unit 107.
[0071]
When determining that any artist name has been selected, the process control unit 101 registers the selected artist name in the U-TOC 11 of the MD 10 (step S46), and ends the data input process.
[0072]
As described above, when the same artist name is already stored in the artist table 91, the user registers the artist name in the MD 10 by selecting a corresponding one of the artist names displayed on the display unit 108. To do. As a result, the disc information can be easily registered.
[0073]
On the other hand, if it is determined in step S45 that no artist name is selected, the processing control unit 101 acquires the artist name input by the user for each character (step S47). That is, the processing control unit 101 displays a predetermined message for prompting the artist name to be input on the display unit 108 and acquires an artist name input for each character from the user via the key input unit 107. .
[0074]
The process control unit 101 determines whether or not the user has finished inputting the artist name (step S48). That is, the processing control unit 101 determines whether or not the instruction information indicating completion of the artist name input is input by the user via the key input unit 107.
[0075]
If the process control unit 101 determines that the input of the artist name has not been completed, the process control unit 101 returns the process to step S47 and repeatedly executes the processes of steps S47 and S48 described above. On the other hand, if it is determined that the input of the artist name is completed, the processing control unit 101 registers the acquired artist name in the U-TOC 11 of the MD 10 and further adds the artist name to the artist table 91 and sorts it. Store (step S49). That is, the process control unit 101 adds the acquired artist name to the artist table 91, sorts the artist names in ascending order, and then updates the contents of the artist table 91.
[0076]
The process control unit 101 ends the data input process after updating the artist table 91. As described above, when an artist name that does not exist in the artist table 91 is input by the user, it is added and stored in the artist table 91. The corresponding artist name can be selected from the artist names displayed in the section 108.
[0077]
Next, the data editing process shown in FIG. 8 will be described.
The process control unit 101 determines whether or not editing for the disc title has been instructed (step S51). In other words, the process control unit 101 determines whether an edit instruction for the disc title included in the text data acquired from the disc playback device 2 by the table update process is input by the user via the key input unit 107. Determine whether or not.
[0078]
If the process control unit 101 determines that editing of the disc title has not been instructed, the process control unit 101 advances the process to step S55 described later. On the other hand, if it is determined that editing for the disc title has been instructed, the processing control unit 101 sequentially displays the contents of the message table 92 stored in the memory 109 (step S52). That is, the process control unit 101 displays the contents of various messages as shown in FIG. At this time, the process control unit 101 displays the selection number on the display unit 108 so that the user can specify the message to be selected.
[0079]
The process control unit 101 determines whether a message has been selected (step S53). That is, the process control unit 101 determines whether or not a selection number corresponding to any message displayed on the display unit 108 is input from the user via the key input unit 107.
[0080]
If the process control unit 101 determines that no message has been selected, the process control unit 101 advances the process to step S55 described below. On the other hand, when determining that the message has been selected, the process control unit 101 registers the disc title to which the selected message is added in the U-TOC 11 of the MD 10 (step S54).
[0081]
For example, when the disc title included in the text data acquired from the disc playback apparatus 2 is “THE VERY BEST” and the message selected by the user is the message “NO. 8” shown in FIG. The control unit 101 registers a disc title as shown in FIG. 9A in the U-TOC 11. That is, the process control unit 101 adds the selected “NO.8” message as a subtitle to the disc title “THE VERY BEST”, and registers this disc title in the U-TOC 11.
[0082]
In this case, the user may be allowed to select a plurality of messages, or a part of the messages may be selected. For example, when a part of the message “NO.8” and the message “NO.2” shown in FIG. 4 are selected by the user, the process control unit 101 sends the U-TOC 11 to FIG. Register the disc title as shown in.
[0083]
Thus, when editing a disc title, by selecting desired information from the message table 92, the disc title with the subtitle added is registered in the MD10. As a result, the disc information can be easily registered.
[0084]
On the other hand, if editing of the disc title is not instructed in step S51 described above, and if no message is selected in step S53, the processing control unit 101 acquires the text acquired from the disc reproducing device 2. The disc title included in the data is directly registered in the U-TOC 11 as a disc title (step S55).
[0085]
After registering the disc title, the processing control unit 101 determines whether or not editing for the artist name is instructed (step S56).
[0086]
If the process control unit 101 determines that editing for the artist name has not been instructed, the process control unit 101 proceeds to step S60 described later. On the other hand, when it is determined that editing for the artist name is instructed, the processing control unit 101 sequentially displays the contents of the message table 92 stored in the memory 109 (step S57).
[0087]
The process control unit 101 determines whether any message has been selected (step S58).
[0088]
If the process control unit 101 determines that no message has been selected, the process control unit 101 advances the process to step S60 described below. On the other hand, when determining that the message has been selected, the process control unit 101 registers the artist name to which the selected message is added in the U-TOC 11 of the MD 10 (step S59).
[0089]
On the other hand, if editing of the artist name is not instructed in step S56 described above, and if no message is selected in step S58, the processing control unit 101 is sent from the disc playback apparatus 2. The artist name included in the text data is directly registered in the U-TOC 11 (step S60).
[0090]
In this way, when editing the artist name, by selecting desired information from the message table 92, the artist name with the subtitle added is registered in the MD10. As a result, the disc information can be easily registered.
[0091]
The data registered in the U-TOC 11 in the disc information registration process described above is displayed when, for example, the target music in the MD is played. That is, the processing control unit 101 controls the signal processing circuit 102 in response to the playback instruction information input from the user via the key input unit 107, plays back the music data of the selected track number, The target disc title and artist name registered in the U-TOC 11 are read out and displayed on the display unit 108.
[0092]
In the above embodiment, the case where the artist name is registered in the MD 10 using the artist table 91 in the data input process has been described. However, the information to be registered in the MD 10 is not limited to the artist name, and other track names are also registered. Applicable to titles, genre names, etc.
[0093]
In the above-described embodiment, the case where the message table 92 is used to edit the disc title and artist name and register them in the MD 10 in the data editing process has been described. The present invention is not limited to names, but can be applied to track titles, genre names, and the like.
[0094]
