Abstract: A file storage apparatus provides an information management method. The information management method includes correlating one or more electronic files with audible cues relative to audio content reproduced via the file storage apparatus, designating respective time intervals of the audio content during which each of the one or more electronic files can be accessed by the file storage apparatus, and retrieving the one or more electronic files of the file storage apparatus upon a predetermined user input provided to the file storage apparatus during one of the respective time intervals of the audio content.

Abstract: To allow desired information to be easily retrieved from various types of information. Information is registered at a music playing position of music data. Music data that are audio data or MIDI data are played. While music data are being played, registration instruction is issued for example with a keyboard. Information is registered at a music playing position corresponding to timing of issuance of the registration instruction. When information is retrieved, music data to which the information had been registered are played. When the music data have come to the music playing position at which desired information has been registered, a retrieval instruction is issued for example with the keyboard. Based on this instruction, information registered at the music playing position is retrieved. As a result, the information can be accessed. Since information is registered to a music playing position of the music data, information can be easily and intuitionally registered and retrieved.
