Is read from the storage position information D and the recording position information T corresponding to the column where is "8".

In the program table 50 shown in FIG.
The number “08” is specified as the storage position information D corresponding to the column where the item “reproduction order” is “8”, and “NULL” is specified for the item “start position” and the item “end position”. Therefore, the music reproduction processing unit 13 sequentially specifies all music recorded on the recording medium RM whose storage position information D is “08” as information to be reproduced eighth, starting from the first music. The user accesses the recording medium RM to reproduce the music.

When the reproduction of the music corresponding to the column where the item “reproduction order” is “8” in the program table 50 as shown in FIG. 2B is completed, the music reproduction processing unit 13 completes the item “reproduction order”. Is read from the storage position information D and the recording position information T corresponding to the column where is "9". However, in the program table 50 shown in FIG. 2B, since the storage position information D and the recording position information T corresponding to the column where the item “reproduction order” is “9” are not specified, the music reproduction processing unit No. 13 determines that all the designated music pieces have been reproduced, and ends the reproduction of the music pieces.

As described above, according to the present invention,
The reproduction order of information such as music pieces recorded on the recording medium RM is determined by the storage position information D indicating the position where information such as track number and chapter number is recorded and the recording position information T for one reproduction order. More than one can be specified. Then, the plurality of designated music pieces can be sequentially reproduced in the order in which the recording position information T increases or decreases. This makes it possible to easily set the procedure for reproducing information such as music recorded on the recording medium RM.

In the first embodiment, setting can be easily performed when music pieces having continuous recording position information T such as track numbers and chapter numbers are sequentially reproduced in accordance with the recording position information T. However, when the same music is repeatedly reproduced a plurality of times, it is necessary to designate the reproduction of one music for one reproduction order as in the related art, which is troublesome. Therefore, the second aspect of the present invention, which simplifies the setting for repeatedly reproducing the same music piece a plurality of times,
A music reproducing apparatus according to the embodiment will be described.

The music reproducing apparatus according to the second embodiment of the present invention is similar to the music reproducing apparatus 1 according to the first embodiment.
It has the same configuration as 00. However, the program processing unit 12 replaces the program table 50 with FIG.
A program table 60 as shown in (b) is created and stored in the program storage unit 20.

The program table 60 includes an item “repeat setting” in addition to the items included in the program table 50 according to the first embodiment.

The item “repeat setting” provided in the program table 60 indicates the number of times the music reproduction processing unit 13 repeatedly reproduces the music to be reproduced in the reproduction order shown in the item “reproduction order”. When the “play key” (not shown) provided in the key input unit 10 is pressed and receives an instruction to play the music recorded on the recording medium RM, the music reproduction processing unit 13 performs the reproduction in each reproduction order. The item “repeat setting” specifies the number of songs to be played and the number of times each song is played repeatedly.

, The recording position information T such as the track number and the chapter number is changed from “01” to “04”.
In the case where the above items are repeatedly reproduced (repeat reproduction) only three times in the order in which the recording position information T increases, the user sets the program table 60 as shown in FIG. That is, the user uses the key input unit 10 to
After “01” is set as the storage position information D, “01” is designated as the item “start position” and “04” is designated as the item “end position” as the recording position information T. further,
Set "3" in the item "Repeat setting".

At this time, the program processing section 12 uses the key input section 10 to store the storage position information D for a certain reproduction order.
After the recording position information T is designated, when the process proceeds to the setting of the number of times of repetition of reproduction of this music, “1” is set as a default value in the item “repeat setting”.

The initial state of the item "repeat setting" is "off", indicating that no repeat reproduction is performed.
If the number of times that the music is repeatedly played is not set, “off” remains set in the item “repeat setting”. The program processing unit 12 keeps the storage position information D for the next reproduction order shown in the program table 60 while “off” is specified in the item “repeat setting” in this manner.
And recording position information T can be designated. However,
Even when the program processing unit 12 shifts to the setting of the item “repeat setting”, it is also possible to set “off” as the number of times the music is repeatedly played back, and designate that the repeat playback is not performed.

When the program processing unit 12 shifts to the setting of the item “repeat setting” or the setting of the music in the next reproduction order without setting the recording position information T by the instruction from the key input unit 10, As the recording position information T, “NU” is set in the item “start position” and the item “end position”.

In the item "random setting", "off" indicating that random playback is not performed is specified. Accordingly, the music reproduction processing unit 13 sets the storage medium RM in which the storage position information D is indicated by “08” as the eighth information to be reproduced.
Are sequentially specified from the first music, and the recording medium RM is accessed to reproduce the music.

When the reproduction of the music corresponding to the column in which the item “reproduction order” is “8” in the program table 70 as shown in FIG. 4B is completed, the music reproduction processing unit 13 completes the item “reproduction order”. Is read from the storage position information D and the recording position information T corresponding to the column where is "9". However, in the program table 70 shown in FIG. 4B, since the storage position information D and the recording position information T corresponding to the column in which the item “reproduction order” is “9” are not specified, the music reproduction processing unit No. 13 determines that all the designated music pieces have been reproduced, and ends the reproduction of the music pieces.

As described above, by setting the reproduction order of music pieces using the program table 70 having the item “random setting”, predetermined conditions among a plurality of music pieces recorded on the recording medium RM can be set. The music selected at random from the satisfying ones can be reproduced with a simple setting.
This also makes it possible to more flexibly reproduce information recorded on the recording medium RM.

The present invention is not limited to reproduction of music, but can be applied to reproduction of various information. For example, the present invention can be applied to a case where a video is reproduced from a recording medium on which video information is recorded, by specifying a reproduction order.

[0152]

As described above, according to the present invention, the reproduction of a plurality of pieces of continuous information is specified collectively in one reproduction order, or the number of times of repeating the predetermined information is specified. be able to. Thereby, the reproduction order of the information recorded on the recording medium can be easily set. Further, it is possible to reproduce information randomly selected from information satisfying a predetermined condition. Thereby, more flexible reproduction of the information recorded on the recording medium can be performed with a simple setting.
