The group management information is information generated to manage one or a plurality of tracks as one group. The group (group name information) and the track number information are related by the group management information. When assigning group name information to a track belonging to a certain group, a method of assigning information to which group the track belongs to each track and a method of assigning the group to the group There is a method of giving which track the track belongs to. In the case of the former method, the group management information is “TNO1 / GroupA, TNO2 / Group

The song “b” to which N2 is assigned and the song “c” to which TON3 is assigned belong to GroupB. The song “d” to which TON4 is assigned and the song “e” to which TON5 is assigned belong to GroupB. I have.

In the grouping process, when a music piece (track) is recorded, the grouping is performed according to some change in the recording of the track detected by the detecting means. The details of the change detected by the detecting means include, for example, an instruction to end recording of a track, an instruction to pause recording of a track, an instruction to change a recording method of a track, and an operation state of a device on a recording source side. Change, recording mode change, source change, etc. Hereinafter, this detection means is divided into recording end detection means, recording suspension detection means, recording method change detection means, operation state change detection means, recording mode change detection means, and recording source change detection means for each change. explain.

Here, in the grouping process, when assigning track number information, the same track number information is not used for different groups, and the track number information for each group is continuously increased from the first number to the last number. A rule for assigning track number information (hereinafter referred to as a “TNO assignment rule”) that has trackability and accepts missing numbers is defined.

Hereinafter, the grouping process will be described with reference to the flowcharts of FIGS.

FIG. 3 is a flow chart showing a grouping process when the recording is completed by the recording end detecting means. Here, a case is shown in which a group from a tune on which recording has been started to a tune on which recording has been completed is included in one group.

First, group name information (for example, GroupA, Group) that the user wants to give to a song (track)
pB...) are set by operating the input unit 52.
For example, when dubbing a song output from a CD playback device to the magneto-optical disk 20, when the user operates the input unit 52 and inputs a recording command, the CPU 51a
Recognizes this (step S1), and starts information recording control of each component of the magneto-optical disk recording / reproducing apparatus 100. Then, the tune output from the CD reproducing device is input to the DRA via the input unit 14 and the data compression encoder / decoder.
When input to the M control circuit 11, the CPU 51a
Recognizing this, the T of the song whose recording has started (currently being recorded)
NO5 as the first song (track) in the group
1c (step S2).

Next, the user operates the input unit 52 to
Input an instruction to end recording a song (track) (for example,
When the "recording stop" button is pressed), the CPU 51a
Recording end detecting means detects this (step S
3) A command for grouping is given to the information adding / generating means.
In response to this, the information adding / generating means of the CPU 51a stores the TNO of the currently recorded song (track) in the RAM 51c as the last song (track) of the group (step S4).

Then, the information adding / generating means of the CPU 51a uses the TNO of the first tune (track) stored in the RAM 51c in step S2 to read the RAM 51 in step S4.
By the TNO of the last song (track) stored in c,
The same group name information (for example, Group A) is assigned to generate group management information. Further, the information addition and generation unit adds TNO to the recorded music (track) based on the TNO addition rule to create a TOC (step S5). This TOC is finally recorded on the innermost peripheral portion of the optical disc 20. Thus, for example, C
When dubbing from D to the magneto-optical disk 20, the process from the start of recording to the end of recording is regarded as one group, and grouping can be performed. When three songs are dubbed from a CD onto the magneto-optical disk 20 on which no song is recorded, TNO1, TNO2, and TNO are added to each song (track).
3 is given, and when dubbing is performed on the magneto-optical disk 20 on which some songs have already been recorded, the duplication is performed from the TNO next to the largest TNO recorded on the magneto-optical disk 20.

FIG. 4 is a flow chart showing the grouping process when the recording suspension detection means performs grouping. Here, a case is shown in which a group from a song whose recording has been started to a song that has been temporarily stopped is regarded as one group.

First, the user operates the input unit 52 to set some group name information to be given to a song (track). In addition, from step S11 to step S1
Steps up to 4 are the same as steps S1 to S4 in the adding process in FIG.

In step S15, when the user operates the input unit 52 to input an instruction to pause recording of a song (track) (for example, press a "pause (pause)" button), the CPU 51a The temporary stop detecting means detects this and gives a grouping instruction to the information adding / generating means. In response to this, the information adding / generating means of the CPU 51a stores the TNO of the recorded music (track) in the RAM 51c as the last music (track) of the group at the time of receiving the grouping command (step S16). In other words, the music from the start of recording to the music that has been paused is one group (first group), and the groups are divided.

Next, the user operates the input unit 52 to
When a command for canceling the pause of the recording of the song (track) is input (for example, the “pause (pause)” button is pressed again), the CPU 51a detects this and returns to step S12. Thus, after release, the TNO of the first recorded song (track) is stored in the RAM 51c as the first song (track) of the next group (second group) (step S12). The process is repeated in the same manner as in FIG. 3, and the same group name information is added to the TNOs of the songs (tracks) belonging to the group for each group, and group management information is generated. In addition, the information adding / generating means, for the recorded music (track),
Based on the TNO assignment rule, TNO is assigned and a TOC is created (step S19). Thus, for example, C
When dubbing is performed from D to the magneto-optical disk 20, the process from the start of recording to the temporary stop can be grouped into one group.

FIG. 5 is a flowchart showing a grouping process when the recording system change detecting means performs grouping. In this example, the number of songs from the song that started recording to the song that was already recorded when the recording method was changed is one.
This shows a case where there are two groups. This is performed, for example, according to the difference in the recording coding mode, and corresponds to a case where a recording method such as ATRAC or ATRAC3 (double mode, quadruple mode) is changed.

First, the user operates the input unit 52 to set some group name information to be given to a song (track). In addition, from step S21 to step S2
Steps 3 and 29 are the same as steps S1 to S4 in the assigning process in FIG. 3, and thus redundant description will be omitted.

In step S24, when the user operates the input unit 52 to input an instruction to pause the recording of a song (track) (for example, press the "pause (pause)" button), the CPU 51a Will detect this.
Here, as in step S16 in FIG. 4, the TNO of the currently recorded song (track) is not stored in the RAM 51c as the last song (track) of the group, and the pause of recording of the song (track) is released. It is determined whether there is an input of an instruction to perform (Step S25). The user
When the user operates the input unit 52 to input an instruction for releasing the pause of recording of a song (track), the CPU 51a
Detects this, and determines whether or not there is an instruction to change the recording method of the music (track) (step S27). For example, the user operates the input unit 52 to play a song (track).
When the recording mode change instruction is input, the recording mode change detecting means of the CPU 51a detects this and gives a grouping instruction to the information adding / generating means. And the CPU 51a
In response to this, at the time when the grouping command is received, the TNO of the recorded music (track) is stored in the RAM 51c as the last music (track) of the group (step S28). . That is, the TNO of the song (track) before the song (track) whose recording method has been changed is stored in the RAM 51c as the last song (track) of the group. As a result, the group from the music whose recording has started to the music before the music whose recording method has been changed becomes one group (first group), and is classified into grape groups.

Then, returning to step S22, the TNO of the first tune (track) whose recording method has been changed is stored in the RAM 51c as the first tune (track) of the next group (second group). Then, if there is no change in the track recording method, a group is formed in accordance with an instruction to end the track recording, similarly to the process of FIG. Hereinafter, the processing is repeated in the same manner as in FIG. 3 or FIG. 4, and the same group name information is added to the TNOs of the songs (tracks) belonging to the group, and the group management information is generated. In addition, the information adding / generating means, for the recorded music (track),
Based on the TNO provision rule, TNO is provided and a TOC is created (step S30). Thus, for example, C
When dubbing is performed from D to the magneto-optical disk 20, it is possible to make one group from the recording start to the music already recorded at the time when the recording system is changed, and to perform the grouping.

FIG. 6 is a flowchart showing the grouping process when the grouping is performed by the operation state change detecting means. Here, a case is shown in which a group from a song whose recording has been started to a song already recorded at the time when a CD exchange command is issued by a device on the recording source side, for example, a CD reproducing device, is taken as one group.

First, the user operates the input unit 52 to set some group name information to be given to a song (track). Steps S41 to S4
Steps 3 and 50 are the same as steps S1 to S4 in the assigning process in FIG. 3, and thus redundant description will be omitted.

Now, in step S44, the CPU 51a
For example, from the signal input from the CD reproducing device, it is determined whether or not the operating state of the device as the sound source has changed, for example, whether or not the reproduction of the CD has been stopped. I do. When the operation state change detection means of the CPU 51a detects, for example, that the reproduction of the CD has stopped, the CPU 51a temporarily stops the recording function (step S45). When there is no recording end instruction from the user (step S46), the CPU 51a
Determines whether there is a pause release instruction (step S47). If the pause has been released and the recording has been resumed, the operation state change detecting means determines whether or not the CD has been replaced (step S48). When the operation state change detecting means of the CPU 51a detects that the CD has been exchanged, it gives a grouping command to the information adding / generating means. In response to this, the information adding / generating means of the CPU 51a stores the TNO of the already recorded tune (track) in the RAM 51c as the last tune (track) of the group when the grouping instruction is received (see FIG. Step S49). That is, the music from the start of the recording to the music already recorded at the time when the CD exchange command is issued becomes one group (first group), and the grouping is performed.

Then, returning to step 42, the TNO of the first music piece (track) after the change of the operation state of the apparatus on the recording source side is changed to the first music piece (track) of the next group (second group). Is stored in the RAM 51c.
Then, if there is no change in the operation state of the CD reproducing apparatus, a group is formed according to the instruction to end the recording of the track, similarly to the processing of FIG. Figure 3 below
Alternatively, the processing is repeated in the same manner as in FIG. 4, and for each group, the TNO of the music (track) belonging to that group
Are given the same group name information to generate group management information. Further, the information addition generation unit adds TNO to the recorded music (track) based on the TNO addition rule to create a TOC (step S5).
1). Thus, for example, from a CD to a magneto-optical disk 2
When dubbing is performed to 0, it is possible to make one group from the recording start to the already recorded music when the operation state of the CD reproducing apparatus is changed, and to perform the grouping. In the example of FIG. 6, the case where the exchange of the CD is detected has been described as an example, but in addition to this, by detecting the exchange of the CD by the disc changer of the apparatus on the recording source side,
The process of step S49 may be performed. In the example of FIG. 6, the device on the recording source side is a CD reproducing device, but other devices include a cassette tape reproducing device and an MD device.
It may be a playback device or a tuner. If the tuner is a tuner, the change of the receiving station is detected, and step S4 is performed.
9 may be performed.

FIG. 7 is a flowchart showing a grouping process when the recording mode change detecting means performs grouping. Here, a case is shown in which a group from a song whose recording has been started to a song already recorded when the recording mode has been changed is one group. Here, the recording mode indicates a special mode such as a mode for recording only the first track of a CD or a mode for recording only a set track.

First, the user operates the input unit 52 to set some group name information to be given to a song (track). Steps S61 to S6
Steps 3 and 69 are the same as steps S1 to S4 in the assigning process in FIG. 3, and thus redundant description will be omitted.

In step S64, when the user operates the input unit 52 to input an instruction to temporarily stop recording a song (track), the CPU 51a detects this. Next, the CPU 51a determines whether or not there is an input of an instruction for canceling the pause of the recording of the music (track) (step S65). When the user operates the input unit 52 to input an instruction for releasing the pause of recording of a song (track), the CPU 51a detects this, and
It is determined whether or not the recording mode of the music (track) has been changed (step S67). When it is determined that the recording mode has been changed, the recording mode change detecting means of the CPU 51a detects this, and gives a grouping command to the information addition generating means. In response to this, the information adding / generating means of the CPU 51a stores the TNO of the already recorded tune (track) in the RAM 51c as the last tune (track) of the group when the grouping instruction is received (see FIG. Step S28). That is, the TNO of the music (track) before the music (track) whose recording mode has been changed
Is the last song (track) of the group
Is stored. As a result, the group from the music whose recording has started to the music before the music whose recording mode has been changed becomes one group (first group), and grouping is performed.

Then, returning to step S62, the TNO of the first song (track) whose recording mode has been changed is stored in the RAM 51c as the first song (track) of the next group (second group). Then, when there is no change in the recording mode of the track, a group is formed according to the instruction to end the recording of the track, similarly to the processing of FIG. Hereinafter, the processing is repeated in the same manner as in FIG. 3 or FIG. 4, and the same group name information is added to the TNOs of the songs (tracks) belonging to the group, and the group management information is generated. Also,
The information addition and generation means adds TNO to the recorded music (track) based on the TNO addition rule, and
C is created (step S70). Thus, for example, when dubbing from a CD to the magneto-optical disk 20, it is possible to make one group from the recording start to the music already recorded at the time when the recording mode is changed.

FIG. 8 is a flowchart showing a grouping process when the recording source change detecting means performs grouping. Here, a case is shown in which a group from a tune for which recording has been started to a tune already recorded when a recording source is changed, for example, a change from a CD to a tuner is made into one group.

First, the user operates the input unit 52 to set some group name information to be given to a song (track). Steps S71 to S7
Steps 3 and 78 are the same as steps S1 to S4 in the assigning process in FIG. 3, and thus redundant description will be omitted.

In step S74, if there is a change in the recording source, for example, a change from one CD player to another CD player, or a change from CD to AM or FM broadcast, the CPU 51a The recording source change detecting means detects this, and gives a grouping command to the information adding / generating means. Then, the information addition generation unit of the CPU 51a responds to this and updates the TNO (steps S75 and S76). This is because the TN assigned to the music (track) before the recording source is switched and the music (track) after the recording source is switched.
This is for distinguishing O. When the recording source change command is received, the information addition generating means of the CPU 51a stores the TNO of the recorded music (track) in the RAM 51c as the last music (track) of the group (step S77). . That is, the TNO of the song (track) before the song (track) whose recording source has been changed is stored in the RAM 51c as the last song (track) of the group. Thus, the group from the song whose recording has started to the song before the song whose recording source has been changed becomes one group (first group), and grouping is performed.

Then, returning to step S72, the TNO of the first song (track) whose recording source has been changed is stored in the RAM 51c as the first song (track) of the next group (second group). Then, when there is no change in the recording source of the track, a group is formed in accordance with an instruction to end recording of the track, similarly to the processing of FIG. Hereinafter, the processing is repeated in the same manner as in FIG. 3 or FIG. 4, and the same group name information is added to the TNOs of the songs (tracks) belonging to the group, and the group management information is generated. Also,
The information addition and generation means adds TNO to the recorded music (track) based on the TNO addition rule, and
C is created (step S79). In this way, it is possible to form one group from the recording start to the music already recorded when the recording source is changed. In addition to switching (switching) individual sources such as CDs and tuners, switching of recording input (DIGITAL, OPT / DIGITA
L, COAXAL / ANAROG). Further, the process of step S77 may be performed by detecting a change in the category code in the digital input. If the input is from a tuner, D
The process of step S77 may be performed by detecting a change in the ATA content.

In the processing of FIGS. 3 to 8,
In the case of air check instead of dubbing from a CD, one TNO is given from the start of recording to the end of recording, and group name information is given to these songs (tracks).

In the processing of FIGS. 3 to 8, the recording end detecting means, the recording temporary stop detecting means, the recording method change detecting means, the operation state change detecting means, the recording mode change detecting means, the recording source change detecting means Has been described, the present invention is not limited to this. For example, another detection means such as a genre of a song (track) or a change in the name of a singer may be detected to perform grouping. May be.

Further, in the processing of FIGS. 3 to 8,
The group name information set by the user may be set not only before the recording of the song (track) but also during the recording. If the group name information is not set, the ROM 5
The name (A, B, C, etc.) set to 1b or the like is given, and after recording, the user can change the name to a desired name.

Also, in FIGS. 3 to 8 described above, the grouping by the respective detecting means in each process has been described. However, the grouping processes in FIGS. 3 to 8 are actually integrated. Become.
