  When the music additional information in the CD information DB corresponding to the set CD is retrieved, the music additional information in the CD information DB corresponding to the CD set via the communication unit 36 is stored in the HDD 37 together with the audio data. The

  The music file stored in the HDD 37 is transmitted via the I / F 32 to the playback device 10 connected for communication. The transmitted music file is stored in the music information database 15, and the music file acquisition process ends.

  The personal information registration program stored in the ROM 18 is appropriately read out and expanded in the RAM 19, triggered by the execution instruction of the personal information registration process input by the operator via the input unit 16. A personal information registration process is executed in cooperation with the developed personal information registration program.

  First, a selection input for inputting personal information is accepted by the operator via the input unit 16, and it is determined whether or not personal information is to be input (step S11). If the operator does not select the personal information input (step S11; NO), the personal information registration process ends. When the operator selects personal information input (step S11; YES), the operator's user ID (Identification) and date of birth information are input via the input unit 16 (step S12).

  Then, based on the input date of birth information, the year number of the year is associated with the operator's school year, age, and the like. For example, when the operator is “born in February 1965”, the association is performed as “1979” when “secondary in junior high school”. The associated result is stored in the HDD 13 as a conversion table (not shown). A data table shown in FIG. 4 is generated based on this conversion table and stored in the HDD 13. As shown in FIG. 4, the data table registers and records the age, age, school year, era, and the like in a state associated with the date of birth information. The data table stores the user ID input in step S12, so that the data table specific to the operator can be specified. After the data table is generated, the data table is displayed on the display unit 17 (step S13). The data table is referred to by the operator, and it is determined whether or not the operator's age, school year, and era do not coincide with the year, and there is a correction (step S14). For example, when “Born in July 1965” and “University 3rd year” calculated are “1986” and “1988” is to be corrected, the correction is performed via the input unit 16. When the correction operator selects that correction is not necessary for the data table (step S14; NO), the personal information registration process is terminated. When the data table needs to be corrected (step S14; YES), the operator inputs a correction to the data table via the input unit 16 (step S15).

  Then, the data table is checked again by the operator, whether or not the data table is checked is input via the input unit 16, and it is determined whether or not the check is OK (step S16). When correction is necessary (step S16; NO), the process proceeds to step S15. If there is no need for correction after confirmation by the operator (step S16; YES), the data table is stored in the birth date conversion database 14 (step S17), and the personal information registration process is terminated.

  Next, music information search processing executed in the playback apparatus 10 will be described with reference to FIG. The music information search process is a process of setting a music search condition in the playback device 10 and selecting a desired music.

  Triggered by the input of the music information search processing execution command from the operator via the input unit 16, the music information search program stored in the ROM 18 is read out as appropriate and expanded in the RAM 19, and expanded in the CPU 11. The music information search process is executed in cooperation with the music information search program.

  The operator inputs the user ID and the number of academic years in the school days via the input unit 16 (step S21). The year information corresponding to the school year of the student age inputted based on the data table corresponding to the input user ID in the date-of-birth date conversion database 14 is designated by the music information search program. Then, the music additional information stored in the music information database 15 is referred to, and the music of the announcement year that matches the instructed year is searched (step S22).

  Then, the searched music name is displayed on the display unit 17 (step S23), and an arbitrary (desired) music name is designated from the music name displayed by the operator.

  Then, it is determined whether or not the desired music title and the year of the year do not match and the operator's correction request input has been made by the input unit 16 (step S24). When it is necessary to correct the year (step S24; YES), the process proceeds to step S21, and the number of academic years in the school days is re-input by the operator. If there is no need to correct the year (step S24; NO), the operator instructs the song name, selects the desired song name from the input unit 16 (step S25), and the song information search process ends.

  Then, a music file corresponding to the desired music selected in step S25 is read from the music information database 15, audio data of the music file is input to the audio output unit 20, and the audio data is input by the audio output unit 20. Playback starts and audio is output.

  As described above, according to the present embodiment, the playback device 10 as an information retrieval device retrieves the year of publication of music as age information related to data based on the grade of the student's age as the personal history information of the operator. Therefore, it is possible to easily search for necessary data using user-specific search items.

  Also, if the desired music title is not announced in the first music title search, the music title search can be performed by re-entering the number of academic years in school days.

  In addition, by inputting the date of birth of the operator, a data table corresponding to the school years as the personal history information and the years (year) as the age information is generated and registered, and stored in the HDD 13. Therefore, it is possible to easily cope with the number of years of the student's school days and the year (year).

  Also, when the first data table is generated, if the grades of the student days do not correspond to the years (year), etc., the correction information such as the grades or years (year) of the student days is input via the input unit 16. By inputting, it is possible to reliably set the number of academic years and the year.

  The operator can view the desired music file via the audio output unit 20, the headphone, or the speaker unit 21 by selecting the desired music file from the displayed music name.
