2. Description of the Related Art FIG. 2 is a block diagram of a conventional DAT recording / reproducing apparatus. In the figure, 1 is a DAT recording / reproducing mechanism, 2
Is a switch group, 3 is a display, 4 is a controller consisting of a microcomputer, 5 is an amplifier, a speaker and the like. The user operates the switches in the switch group 2 to record / reproduce the input voice or record / reproduce information other than voice.

In DAT, various signals are recorded on one track of the magnetic tape T by dividing the area.
FIG. 3 shows an example of the data arrangement. A voice signal is recorded in the main area, an information signal is recorded in the sub area, and a tracking signal is recorded in the ATF area. Of these, in the sub-area, it is possible to re-record without changing the signals in other areas, so it is possible to record an information signal at the same time while recording an audio signal, or to record only an information signal while reproducing an audio signal. It is also possible to record.

FIG. 4 shows the standard of the above-mentioned sub-area, and the information signal is recorded in the sub-ID part and the sub-data part. The information signal of the sub ID part has a predetermined use, and a signal indicating the beginning of a song and a song number are recorded.

The information signal of the sub-data part indicates the contents by the pack item and records the data in the pack data, and the pack item is defined as shown in Table 1. Not all the content is necessary and can be selected by the manufacturer or user.

[0006]

[Table 1]

The switch group 2 shown in FIG. 2 is provided with a plurality of switches corresponding to the pack item. For example, if a "running time" switch is input during recording or reproduction of voice, the sub data area The pack item 0011 indicating the running time and the running time at that time are recorded in the pack. Then, during reproduction, the running time is displayed on the display at the recorded position.

[0008]

However, the conventional DAT
Then, the sub-data area was used only for the purpose as shown in Table 1, and its utilization range was such as displaying time on the display and displaying characters.
That is, although it is convenient as a function, it may or may not be for enjoying music, and since it did not control the music signal to be reproduced, even if there is a data area, , It could not be said that it is being used effectively.

An object of the present invention is to provide a recording / reproducing system in which a data area such as a sub-data portion can be used for enjoying music and music can be reproduced with a more realistic feeling.

[0010]

In order to achieve the above object, the recording / reproducing apparatus of the present invention stores a storage means for storing data relating to a plurality of music together with control data corresponding to each music, and contents of the control data. A determination means for determining, a setting means for setting the playback state of the corresponding music based on the determined control data, and a playback means for playing the music in the playback state set by the setting means. That is the summary. In a preferred embodiment of the present invention, the setting means includes a lighting controller, a sound field unit controller and a slide photo controller.

[0011]

When the data is reproduced, the data recorded in the area independent of the music data is read out, and the listening environment suitable for the music data reproduced by the data is set.

[0012]

Embodiments of the present invention shown in the drawings will be described below.
1 is an embodiment of a recording / reproducing system according to the present invention, in which the same reference numerals as those in FIG. 2 designate the same or similar devices, 5 is a slide photograph controller, 6 is a sound field unit controller, 7 is a lighting controller, 8 is a lighting fixture,
Reference numeral 9 is a sound field unit, an amplifier, a speaker, and 10 is a slide photo projector. In this embodiment, the lighting controller 7
Illustrates the case where the controller 4 switches the illumination of the listening room and the setting of the sound field by the sound field controller 6 and the control of the slide photo controller 5 of the slide photo projector 10 in accordance with the music by the controller 4 during DAT tape reproduction.

FIG. 5 shows the contents recorded on the tape, and Table 2 shows the contents of each control signal. Each data is recorded in a pack in the sub data area as in the conventional case.

[0014]

[Table 2]

The pack item of each control signal may be determined by the recording / reproducing apparatus. For example, it is assumed that the unspecified portion of Table 1, that is, the areas of 1011 to 1110 are applied. In FIG. 5, for convenience, lighting data is assigned to pack 1, sound field is assigned to pack 2, and slide data is assigned to pack 3. It does not matter which data is stored in, or other data may be exchanged in the same pack.

Recording of each data may be performed while recording music and voice or after recording music and voice in advance, but it is performed by inputting a switch in the switch group of FIG. 1 according to music and voice. Be seen. When the tape T thus recorded is reproduced, the recording / reproducing apparatus reads the sub data data while reproducing the music and voice of the main data. If the sub-data pack item is a light, the data is sent to the lighting controller, if it is sound field data, the data is sent to the sound field unit controller, and if it is a slide photo, the data is sent to the slide photo controller.

Each data is set as shown in Table 2,
Each controller controls each device accordingly. For example, the lighting controller 7 switches the connected lighting equipment, the sound field controller 6 adds reverberation to the input sound, and the slide picture controller 5 sets the picture No. Corresponding to, the number of sheets to be fed of the slide photo projector 10 is calculated and the projector is operated.

Explaining with the example of FIG. 5, the reproducing operation is started in step S1 of the flowchart of FIG. 6, and in music 1, the lights B and C are turned on and the first slide photograph in a sound field like a live house. Is projected. That is, regarding the sound field, the sound field control data 3 corresponding to the music 1 is read from the pack 2 in the sub area and set to a sound field like a live house (step S2).
S3). When the song changes to music 2, all the lights are turned off and the second slide photograph is switched to the sound field like a large hall. Then, in the middle of music 2, the slide photo is changed to the third photo. Next, a voice such as song description 1
When turned to, all the lights are turned on and sound is played without reverberation (slide photos are off). Each time the music ends, it is detected whether or not the reproduction operation ends (steps S4 and S5), and the desired sound field can be set according to the type of music. Since only the information data can be rerecorded in DAT, the setting can be changed any number of times. Although the DAT is taken as an example, the same can be applied to any recording / reproducing apparatus that can record information data in addition to music data and can re-record only the information data.

FIG. 7 is a more detailed flowchart for explaining the operation of the above embodiment based on FIG. 6, and FIG. 8 is a diagram showing an example of recording data and codes on the tape. As shown in FIG. 8, on the tape T, a reproduction code is provided at the forefront and a reproduction end code is provided at the last of a plurality of music 1 to 3 to be reproduced, and these codes are detected to control the start or end of the reproduction operation. ..
It should be noted that the end of music may be added with a code indicating the end of each music, or the end of music may be judged to be due to the absence of sound data for a predetermined time.

In FIG. 7, the tape running is turned on in step S11, and it is determined in step S12 whether or not there is a reproduction start code. As a result, if it is NO, it returns to the original,
If YES, the sound field data is determined in step S2, and in any of steps S3-1 to S3-n, the sound field 1 to
Set n. After that, if it is determined that the music ends in step S41, the presence or absence of the reproduction end code is determined in step S51. If YES, the process ends. If NO, the process returns to step S2.

[0021]

As described above, according to the present invention, it is possible to automatically switch the listening environment, which conventionally requires the user to switch to music or voice each time. The data area can be used effectively.
