Step S21 of deciding whether to create the digest music actual data of all the songs on the recording medium 1 or the digest music actual data of only the favorite songs, and giving an instruction.
In the case where the digest music actual data of only the favorite music is created, first, a desired music is designated from the music recorded on the recording medium 1 (step S24). With this designation, a message such as "Play back. Please press the digest REC button at your favorite place" is displayed on the LCD display unit 13. According to the designation of the desired music, the digest music actual data of the specified music is created and read while the recording medium 1 is being reproduced (step S25). that time,
It is determined whether or not the ROM 5 has a remaining amount (step S26). If there is a remaining amount, the operation of registering the created digest music actual data and its accompanying information (see FIG. 5) in the ROM 5 is continued (step S27), and the operation of creating and registering the digest music actual data of the desired music is performed. Is determined, and if there is no actual digest music data of the specified music to be registered, the digest RE
The C mode ends (step S28).

Next, a specific example of the procedure for creating and registering the actual digest music data while reproducing the designated music piece in step S26 will be described in further detail. By pressing the “Digest REC button” at a desired part while playing the designated music piece on the recording medium 1, recording of the digest part is started, and after t (sec or byte), or as soon as the remaining memory capacity is exhausted, automatic recording is performed. When the recording is completed, the digest music actual data of the desired t (sec or byte) portion is created and registered in the ROM 5 together with the accompanying information.

In addition, when the digest music actual data of the favorite part of the designated music piece is created and registered, it can be performed in the following procedure. That is, while the designated song is being played, the first operation of the “Digest REC button” is performed at a desired portion to start recording the digest portion, and then the second “Digest R” within t (sec or byte).
By pressing the "EC button" and terminating the recording, it is possible to create and register the digest music actual data of a desired portion shorter than that according to the first procedure.

Next, the manner of recording and registering the actual digest music data and the accompanying information in the ROM 5 will be described based on the data registration structure of the ROM 5 shown in FIG. ROM
5 is provided with a file numbered ($ 1, $ 2, ...) for each song, and for each file,
Information such as the file name of the original song, the registration (copy) date and time, the digest data address (start and end addresses), the actual digest music data, and the specification information of the opening song at power-on are recorded. Except for the actual digest music data, they are supplementary information. This example shows that the actual digest music data is compressed data in the MP3 format. In the compressed data in the MP3 format, information is recorded for each frame. The numbers are shown. Also, an aspect is shown in which the digest music of file # 2 is specified as the opening music.

Next, an example of a reproducing procedure in the music reproducing apparatus having such a configuration will be described with reference to a flowchart shown in FIG. In the music reproducing apparatus having the above-described configuration, it is a general reproducing method to perform reproduction by designating the file number of the actual digest music data recorded and registered in the ROM 5, but the reproducing method shown in FIG. Means that when the recording medium 1 is mounted, priority is given to music reproduction on the recording medium 1, and when the recording medium 1 is not mounted, R
The opening music of the digest music recorded in the OM is reproduced to be used for confirming the power ON.

That is, when the power is turned on (the power is turned on), first, the presence or absence of the mounted recording medium 1 is detected (step S31). If the recording medium 1 is mounted, the reproduction of music from the recording medium 1 is performed. Is set to the standby state in preparation for the priority execution (step S32). When the recording medium 1 is not mounted, in order to provide a function of opening and reproducing the actual digest music data,
First, it is determined whether or not the digest music actual data is recorded in the ROM 5 (step S33). ROM
If there is no actual digest music data in 5, the reproduction is not possible, so that a standby state is set. However, if there is digest data, it is determined whether or not an opening music has been designated (step S 34), and the opening music is designated. If so, the opening designated song of the actual digest music data is reproduced from the ROM 5 (step S35).
A plurality of opening songs can be specified. The files are played back in the order of file number. At the time of singular designation, reproduction may be repeated. On the other hand, if the opening song has not been designated, the first song of the actual digest music data is reproduced from the ROM 5 as the opening song (step S36).

By providing the function of playing the opening music of the actual digest music data when the power is turned on, it is possible to easily and smartly confirm the power-on state without visually recognizing the apparatus. .

The reproduction of the digest music actual data recorded in the ROM 5 is performed in the following manner in addition to the reproduction mode in which the file number is specified as described above or the opening music is reproduced. It can be played back in a manner. That is, all files in which the digest music actual data are recorded in the ROM 5 are sequentially and continuously reproduced, all files are reproduced randomly, and all files are t '(t or shorter) than t (sec or byte). s
ec or byte), for example, the first 5 seconds of a 20-second digest music part during recording can be played back sequentially or randomly (medley playback).

The digest data recorded in the ROM (flash memory) 5 can be deleted for each file or collectively. However, the digest music actual data is prepared from a recording medium having no digest data and is stored in the ROM. In the case of recording and registration, it is convenient to delete the digest music actual data and other accompanying information while leaving only the file name of the original music piece of the registered digest music actual data and its digest data address. In other words, only the file name of the original song and the digest data address require only a few bytes of capacity, so that the load on the storage capacity of the ROM is hardly reduced, and the same recording medium is mounted again and the digest music is re-installed. When reproducing actual data, it is possible to easily reproduce the digest music actual data by reusing information remaining without erasing without performing the same operation.
