BACKGROUND OF THE INVENTION
The present invention relates to an information recording apparatus provided with means for assigning track number information to each track recorded on an information recording medium.
[0002]
[Prior art]
Information recording media for recording music information and video information include linear information recording media represented by cassette tape, DAT (digital audio tape) 8 mm tape, LD (laser disc), CD (compact disc), Disc-shaped information recording media represented by MD (mini disc), DVD (digital versatile disc) and the like are known.
[0003]
In recent years, disk-like information recording media have been remarkably widespread in combination with the advantage that information can be written and rewritten, and access to recorded information is quick.
[0004]
When recording a song (hereinafter simply referred to as “song”) on this disk-shaped information recording medium, for example, one song is set as a unit of “track”, and track number information is assigned to this track for management. Can do. Such track number information includes the disc name, song name, number of songs, performance time, start position and end position of the song on the disc (when the position is managed by time information, start time and end time), etc. It is included in management information called TOC (Table of content) recorded on the innermost periphery of the disc together with information for managing the recording data. When a recorded music is reproduced, the user can select a recorded music by operating such a disc recording / playback editing apparatus and specifying such track number information.
[0005]
Recently, the number of songs that can be recorded on one disc-shaped information recording medium can be remarkably increased by improving the information recording density on the disc-shaped information recording medium and establishing a new information compression method. For example, in MD, an information compression method called ATRAC (Adaptive TRansform Acoustic Coding) has been conventionally used. However, recently, information is compressed by an information compression method called ATRAC3, which has a compression efficiency twice or four times that of conventional ATRAC. The MDLP standard for recording was established. According to this ATRAC3, a standard recording time of 80 minutes MD can record up to 320 minutes in the quadruple mode. According to such a new information compression method, for example, even if one song is about 5 minutes, about 60 songs can be recorded on the disc.
[0006]
[Problems to be solved by the invention]
However, when such a large number of songs can be recorded, it takes a lot of time to select a song to be played back, and the management of the song becomes very troublesome. Therefore, a method has been proposed in which a user can collect one or a plurality of songs and group them, and manage the songs for each group (hereinafter referred to as “group management”). In such group management, since information such as the same group name is assigned to songs belonging to the same group (for example, the same genre), the user first designates the group name, and thereafter Since the track number information belonging to the group can be designated, the music to be played can be selected efficiently.
[0007]
However, in order to manage the group, it is determined which song and which song are to be grouped in which song to be recorded, which group from which song to which song, and so on. Group name etc. must be entered, especially when recording many songs from various media, there is a risk that grouping will be cumbersome and will give the user an operational load There is a fear.

Note that an A / D converter for converting an analog signal into a digital signal and a D / A converter for converting a digital signal into an analog signal are not shown.
[0034]
The system controller 51 includes a CPU 51a, a ROM 51b, and a RAM 51c, controls each component in the information recording / reproducing unit 50, and records, reads, and reproduces information on the magneto-optical disk 20. The CPU 51a of the system controller 51 has functions as an information adding and generating unit and various detecting units in the present invention. When recording information on the magneto-optical disk 20, a grouping process (hereinafter referred to as "grouping process"). Management information referred to as a TOC that has been subjected to The TOC is recorded on the innermost periphery of the magneto-optical disk immediately before the magneto-optical disk 20 is taken out from the magneto-optical disk recording / reproducing apparatus 100. The ROM 51b stores a grouping processing program and the like, and the RAM 51c is mainly used as a work area.

The display unit 53 displays the performance state of the magneto-optical disk recording / reproducing apparatus 100 and displays necessary information for the user.
[0035]
In such a configuration, during the information recording operation of the magneto-optical disk recording / reproducing apparatus 100, an input signal (for example, a song reproduced from a CD reproducing apparatus, AM, FM broadcast) input to the input unit 14 is data-compressed. The data is supplied to the encoder / decoder 13 and subjected to data compression / encoding processing. Based on an instruction from the system controller 10, the music piece data is temporarily written in the DRAM by the DRAM control circuit 11. Then, it is read out at a predetermined timing and sent to the EFM encoder / decoder 9. The EFM encoder / decoder 9 performs an encoding process such as EFM modulation, and then supplies it to the head drive circuit 5. The head drive circuit 5 supplies a magnetic head drive signal to the magnetic head 3 in accordance with the encoded compressed data. At the same time, the output of the laser diode of the optical pickup 2 is increased to increase the output of the magneto-optical disk 20. Music data is recorded on the magneto-optical disk 20 by heating the magnetic film above the Curie temperature. At this time, the servo control circuit 8 performs servo control based on an instruction from the system controller 51.
[0036]
As described above, when information is recorded on the magneto-optical disk 20, the system controller 51 performs a grouping process which is a characteristic part of the present invention. This grouping process will be described in detail below. First, the logical structure of the TOC related to the grouping process will be described with reference to FIG. The TOC according to the present embodiment is obtained from group management information including group name information in addition to management information such as a disc name, track number information given to one track, song name, number of songs, and performance time. It is configured. This group management information is information generated for managing one or more tracks as one group. With this group management information, the group (group name information) and the track number information are related. In addition, 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 group to the group. There is a method for assigning which track the track belonging to. In the case of the former method, the group management information is in the form of << TNO1 / Group A, TNO2 / Group B, TNO 3 / Group A, TNO 4 / Group B, TNO 5 / Group C >>, and in the case of the latter method, the group management information is << Group A / TNO1 & TNO2 & TNO3, Group B / TNO4 & TNO5 >>. The meanings of “TON1” and “Group A” will be described in detail later. In the present embodiment, the track and the music have a one-to-one correspondence.
[0037]
FIG. 2 is a diagram showing the relationship (logical structure) of the disc name, group name information, track number information, and track (song) name in such a TOC. In FIG. 2, “Disc” indicates a disk name. “Group A” indicates a group managed by the name “A” (Group B, C, D... Also indicates a group managed by each name). “TON1” indicates that the track number information has a number “1” (TON2, 3,... Also indicate the track number information of each number). “A” indicates that the track is named “a” (here, a song named “a”) (b, c, d... Show).
[0038]
In the example of FIG. 2, Group A and Group B are registered in one Disc, and in addition, a song “a” with TON1 and a song “b” with TON2 and TON3 are added to Group A. The song “c” to which TON4 is assigned and the song “e” to which TON5 is assigned belong to Group B.
[0039]
In the grouping process, the grouping is performed according to some change related to the track recording detected by the detecting means when the music (track) is recorded. The contents of the change detected by this detection means include, for example, an instruction to end track recording, an instruction to pause track recording, an instruction to change the recording method of the track, and the operating state of the recording source device. Change, recording mode change, source change and so on. Hereinafter, this detecting means is divided into a recording end detecting means, a recording pause detecting means, a recording method change detecting means, an operation state change detecting means, a recording mode change detecting means, and a recording source change detecting means for each change content. explain.
[0040]
Here, in the grouping process, when adding track number information, (1) the same track number information is not used for different groups, and (2) the track number information for each group is changed from the first number to the last number. A rule for adding track number information (hereinafter referred to as a “TNO assigning rule”) is defined in order to increase continuity and allow missing numbers.
[0041]
Hereinafter, the grouping process will be described with reference to the flowcharts of FIGS.
[0042]
FIG. 3 is a flowchart showing grouping processing when grouping is performed by the recording end detection means. Here, the case where the music from the recording start to the recording end is made into one group is shown.
[0043]
First, the user sets group name information (for example, Group A, Group B...) Desired to be given to a song (track) by operating the input unit 52. For example, when dubbing a song output from the CD playback device onto the magneto-optical disk 20, when the user operates the input unit 52 to input a recording command, the CPU 51a recognizes this (step S1). Information recording control of each component of the magneto-optical disk recording / reproducing apparatus 100 is started. When the music output from the CD playback device is input to the DRAM control circuit 11 via the input unit 14 and the data compression encoder / decoder, the CPU 51a recognizes this and recording starts (currently recording). The TNO of the song is stored in the RAM 51c as the first song (track) of the group (step S2).
[0044]
Next, when the user operates the input unit 52 to input an instruction to end recording of a song (track) (for example, press the “recording stop” button), the recording end detection unit of the CPU 51a detects this. (Step S3), a grouping command is given to the information addition generating means. In response to this, the information adding / generating unit 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).
[0045]
The information adding and generating means of the CPU 51a uses the same group name from the TNO of the first song (track) stored in the RAM 51c in step S2 to the TNO of the last song (track) stored in the RAM 51c in step S4. Information (for example, Group A) is assigned to generate group management information. Further, the information addition generating unit assigns TNO to the recorded music (track) based on the TNO addition rule, and creates a TOC (step S5). This TOC is finally recorded on the innermost periphery of the optical disc 20. Thus, for example, when dubbing from the CD to the magneto-optical disk 20, the grouping can be performed with one group from the start of recording to the end of recording. In addition, when three songs are dubbed from a CD to the magneto-optical disk 20 on which no song is recorded, TNO1, TNO2, and TNO3 are assigned to each song (track), and some songs are already recorded. When dubbing on the disk 20, it is given from the TNO next to the maximum TNO recorded on the magneto-optical disk 20.
[0046]
FIG. 4 is a flowchart showing grouping processing when grouping is performed by the recording pause detection means. Here, a case is shown in which music from the recording start to the paused music is made into one group.
[0047]
First, the user sets several pieces of group name information to be assigned to a song (track) by operating the input unit 52. Note that steps S11 to S14 are the same as steps S1 to S4 in the assigning process of FIG.
[0048]
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 the “pause” button), the CPU 51a pauses. The detection means detects this and gives a grouping command to the information addition generation means. In response to this, the information giving / 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 when the grouping instruction is received (step 51). S16). That is, the music from the recording start to the paused music forms one group (first group), and grouping is performed.
[0049]
Next, when the user operates the input unit 52 to input a command for releasing the pause of the recording of the music (track) (for example, press the “pause” button again), the CPU 51 a This is detected, and the process returns to step S12. As a result, 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). Thereafter, the processing is repeated in the same manner as in FIG. 3, and the same group name information is given to the TNOs of the songs (tracks) belonging to the group for each group to generate group management information. Further, the information addition generation unit assigns TNO to the recorded music (track) based on the TNO addition rule, and creates a TOC (step S19). In this way, for example, when dubbing from a CD to the magneto-optical disk 20, the grouping can be performed with one group from the start of recording to the temporary stop.
[0050]
FIG. 5 is a flowchart showing the grouping process when grouping is performed by the recording method change detection means. Here, a case is shown in which a group from a song that has started recording to a song that has already been recorded when the recording method is changed is made into one group. For example, this is performed by different recording coding modes, and corresponds to a case where there is a change in recording method such as ATRAC, ATRAC3 (double mode, quadruple mode).
[0051]
First, the user sets several pieces of group name information to be assigned to a song (track) by operating the input unit 52. Step S21 to step S23 and step 29 are the same as step S1 to step S4 in the assigning process of FIG.
[0052]
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” button), the CPU 51a Is detected. Here, as in step S16 of 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 the song (track) recording is canceled. It is determined whether or not there is an input of an instruction to do so (step S25). When the user operates the input unit 52 to input an instruction for releasing the pause of the recording of the song (track), the CPU 51a detects this and gives an instruction to change the recording method of the song (track). Whether or not (step S27). For example, when the user operates the input unit 52 and inputs an instruction to change the recording method of a tune (track), the recording method change detection means of the CPU 51a detects this and sends a grouping command to the information addition generation means. give. In response to this, the information giving / 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 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 music from the recording start to the music before the music whose recording method has been changed becomes one group (first group), and the grapes are divided.
[0053]
Then, returning to step S22, the TNO of the first song (track) whose recording method has been changed is stored in the RAM 51c as the first song (track) of the next group (second group). If there is no further change in the track recording method, a group is formed in response to an instruction to end track recording, as in the process of FIG. Thereafter, the processing is repeated in the same manner as in FIG. 3 or FIG. 4, and for each group, the same group name information is given to the TNOs of the songs (tracks) belonging to the group, and group management information is generated. Further, the information addition generating unit assigns TNO to the recorded music (track) based on the TNO addition rule, and creates a TOC (step S30). Thus, for example, when dubbing from a CD to the magneto-optical disk 20, it is possible to divide into one group from the start of recording to a song that has already been recorded when the recording method is changed.
[0054]
FIG. 6 is a flowchart showing grouping processing when grouping is performed by the operation state change detection means. Here, a case is shown in which a recording source device, for example, a CD playback device, from a song that has started recording, to a song that has already been recorded at the time when a CD replacement command is given is grouped into one group.
[0055]
First, the user sets several pieces of group name information to be assigned to a song (track) by operating the input unit 52. Since steps S41 to S43 and step 50 are the same as steps S1 to S4 in the assigning process of FIG.
[0056]
In step S44, the operation state change detection means of the CPU 51a, for example, determines whether or not there is a change in the operation state of the device that is the sound source from the signal input from the CD playback device. Determine whether it has been stopped. For example, when the operation state change detecting means of the CPU 51a detects that the reproduction of the CD is stopped, the CPU 51a temporarily stops the recording function (step S45). If there is no recording end instruction from the user (step S46), the CPU 51a determines whether or not there is a temporary stop cancellation instruction (step S47). When the pause is released and the recording is resumed, the operation state change detecting means determines whether or not the CD has been exchanged (step S48). When the operation state change detecting means of the CPU 51a detects that the CD has been exchanged, it gives a grouping instruction to the information addition generating means. In response to this, the information giving / 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 S49). That is, from the music that has been recorded to the music that has already been recorded at the time when the CD replacement command is given, one group (first group) is formed, and grouping is performed.
[0057]
Then, returning to step 42, the TNO of the first song (track) after the change of the operation state of the recording source side device is stored in the RAM 51c as the first song (track) of the next group (second group). Remembered. If there is no further change in the operating state of the CD playback device, a group is formed in response to an instruction to end track recording, as in the process of FIG. Thereafter, the processing is repeated in the same manner as in FIG. 3 or FIG. 4, and for each group, the same group name information is given to the TNOs of the songs (tracks) belonging to the group, and group management information is generated. Further, the information addition generating unit assigns TNO to the recorded music (track) based on the TNO addition rule, and creates a TOC (step S51). Thus, for example, when dubbing from the CD to the magneto-optical disk 20, it is possible to perform grouping by grouping songs that have already been recorded from the start of recording to the point in time when the operation state of the CD playback apparatus is changed. it can. In the example of FIG. 6, the case where the exchange of the CD is detected has been described as an example. In addition, the process of step S <b> 49 is performed by detecting the CD exchange by the disk changer of the recording source device. It doesn't matter. In the example of FIG. 6, the recording source side apparatus is a CD reproducing apparatus, but other apparatuses may be a cassette tape reproducing apparatus, an MD reproducing apparatus, and a tuner. If it is a tuner, the process of step S49 may be performed by detecting a change in the receiving station.
[0058]
FIG. 7 is a flowchart showing the grouping process when grouping is performed by the recording mode change detection means. Here, a case is shown in which a group from a song that has started recording to a song that has already been recorded when the recording mode is changed is made into one group. Here, the recording mode indicates a special mode such as a mode for recording only the first song of a CD or a mode for recording only a set track.
[0059]
First, the user sets several pieces of group name information to be assigned to a song (track) by operating the input unit 52. Since steps S61 to S63 and step 69 are the same as steps S1 to S4 in the assigning process of FIG.
[0060]
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 releasing 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 the recording of the song (track), the CPU 51a detects this and whether there is a change in the recording mode of the song (track). It is determined whether or not (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 giving / 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 S28). That is, the TNO of the song (track) before the song (track) whose recording mode has been changed is stored in the RAM 51c as the last song (track) of the group. As a result, the music from the recording start to the music before the music whose recording mode has been changed becomes one group (first group), and grouping is performed.
[0061]
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). If there is no further change in the track recording mode, a group is formed in response to an instruction to end track recording, as in the process of FIG. Thereafter, the processing is repeated in the same manner as in FIG. 3 or FIG. 4, and for each group, the same group name information is given to the TNOs of the songs (tracks) belonging to the group, and group management information is generated. Further, the information addition generating unit assigns TNO to the recorded music (track) based on the TNO addition rule, and creates a TOC (step S70). Thus, for example, when dubbing from the CD to the magneto-optical disk 20, it is possible to make one group from the start of recording to the music already recorded when the recording mode is changed.
[0062]
FIG. 8 is a flowchart showing the grouping process when grouping is performed by the recording source change detection means. Here, a case is shown in which one song is recorded as a group from a song that has started recording to a recording source change, for example, a song that has already been recorded when there is a change from a CD to a tuner.
[0063]
First, the user sets several pieces of group name information to be assigned to a song (track) by operating the input unit 52. Since steps S71 to S73 and step 78 are the same as steps S1 to S4 in the assigning process of FIG.
[0064]
In step S74, when the recording source is changed, for example, when changing from one CD player to another CD player, or from CD to AM or FM broadcast, the recording source of the CPU 51a is changed. The detection means detects this and gives a grouping command to the information addition generation means. And the information addition production | generation means of CPU51a responds to this, and updates TNO (step S75, S76). This is for distinguishing the TNO given to the music (track) before the recording source is switched and the music (track) after the recording source. Then, the information adding and generating unit of the CPU 51a stores the TNO of the recorded song (track) in the RAM 51c as the last song (track) of the group at the time of receiving the recording source change command (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. As a result, the music from the recording start to the music before the music whose recording source is changed becomes one group (first group), and grouping is performed.
[0065]
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). If there is no further change in the track recording source, a group is formed in accordance with an instruction to end track recording, as in the process of FIG. Thereafter, the processing is repeated in the same manner as in FIG. 3 or FIG. 4, and for each group, the same group name information is given to the TNOs of the songs (tracks) belonging to the group, and group management information is generated. Further, the information addition generating unit assigns TNO to the recorded music (track) based on the TNO addition rule, and creates a TOC (step S79). In this way, it is possible to form one group from the start of recording to the songs that have already been recorded when the recording source is changed. In addition to changing (switching) individual sources such as CDs and tuners, the present invention can be applied to switching recording inputs (DIGITAL, OPT / DIGITAL, COAXAL / ANAROG). Further, the process of step S77 may be performed by detecting the change of the category code in the digital input. In the case of input from the tuner, the process of step S77 may be performed by detecting a change in DATA contents such as FM multiplexing.
[0066]
3 to 8, in the case of air check instead of dubbing from CD, one TNO is given from the start of recording to the end of recording, and these songs (tracks) are assigned. Group name information is given.
[0067]
3 to 8 are grouped by a recording end detection unit, a recording pause detection unit, a recording method change detection unit, an operation state change detection unit, a recording mode change detection unit, and a recording source change detection unit. However, the present invention is not limited to this, and other detection means, for example, a genre of a song (track) or a change of a singer name may be detected to perform grouping. Good.
[0068]
Further, in the processes of FIGS. 3 to 8, the group name information set by the user may be set not only before recording of a song (track) but also during recording. In addition, when group name information is not set, names (A, B, C, etc.) set in advance in the ROM 51b or the like are given, and after recording, the user can change the name to a desired name.
[0069]
Further, in FIGS. 3 to 8 described above, the grouping by the respective detection means has been described in each process. However, the grouping processes in FIGS. 3 to 8 are actually integrated.
[0070]
As described above, according to the present embodiment, when a song (track) is recorded, grouping is automatically performed according to any change related to track recording (for example, change in recording method, change in recording mode, etc.). Therefore, the user only has to input the group name information and can reduce the trouble of performing grouping by himself / herself, so that the operation load on the user can be reduced.
[0071]
In the above embodiment, the case where the information recording apparatus of the present invention is applied to the magneto-optical disk recording / reproducing apparatus has been described. However, the recording / reproducing apparatus for information recording media such as MD, CD, DVD, LD, Alternatively, the present invention can be applied to an integrated audio device that can use a plurality of these information recording media, an in-vehicle audio device, and the like.
[0072]
【The invention's effect】
  As described above, according to the invention described in claim 1,Since the grouping is performed according to the change in the operation state of the recording source device detected by the operation state change detection means, it is possible to reduce the time and effort for grouping by the user, and to perform the grouping efficiently. Therefore, the operation load on the user can be reduced.
[0081]
  Claim3According to the invention described in (1), since the continuous track number information is given to the track, the group management can be efficiently performed together with the group management information.
[0082]
  Claim4According to the invention described in the above, since the configuration is such that the track number information given to the track is distinguished before and after receiving the grouping command, the user can also identify the group by track number information. It can be easily grasped.
