Embodiment Construction

[0021]FIGS. 1A to 1C show an example of a recording format when a hard disk drive is used as a recording medium. In other words, as shown in FIG. 1A, digital audio data for music pieces 1 to N is recorded as files 1 to N in a user area USRA of the hard disk drive. In this case, the digital audio data in the files 1 to N is data-compressed, for example, in an MP3 format. Reference marks adr1 to adrN represent start addresses of clusters (cluster numbers) in which the files 1 to N are recorded.

[0022]In addition, a title table TTBL, which is shown, for example, in FIG. 1B, is stored in the hard disk drive. The title table TTBL represents the relationships between titles ttl1 to ttlN of the music pieces 1 to N recorded in the user area USRA and the start addresses adr1 to adrN of the files 1 to N in the user area USRA.

[0023]In addition, a subjective data table SBJT, which is shown, for example, in FIG. 1C, is stored in the hard disk drive. The subjective data table SBJT represents the r...
