Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an audio player, and more specifically to an audio player that plays a digital audio disc.
[0002]
[Prior art]
20 and 21 are music selection screens in a conventional audio player. In FIG. 20, the track number (Tr01) being played and the playback time (1 minute 23 seconds) are displayed in 2001, and when the button 2003 is pressed, the music immediately before the music currently being played is played back. The mechanism is such that the music immediately after the music currently being played is played by pressing 2005. Also, when the disc is inserted, the music is played from the music at the head of the disc when the button 2009 is pressed. When the button 2009 is continuously pressed, playback starts from the second song on the disc, and when the button 2007 is pressed, the selected song is selected. It is a mechanism to select from the music one before the music.
[0003]
On the other hand, the jukebox type audio player shown in FIG. 21 is of a type in which a music file to be reproduced is selected in advance from the array, and the music file to be reproduced is selected from the song list list 2101. By pressing an add button 2105, a plurality of music files can be registered in the designated song list list 2103. When canceling a music file registered in the designated song list 2103, the user selects a music file to be canceled from the designated song list 2103 and presses the delete button 2107. The music registered in the designated music list 2103 is played in order when a playback start operation is performed.
Thus, all conventional audio players handle music and music files in a storage medium (hereinafter referred to as a disc) as a static one-dimensional array.
[0004]
[Problems to be solved by the invention]
However, in recent years, audio compression techniques (such as MP3) have been developed, and it has become possible to make music files at high compression rates. When these audio compression techniques are applied, it is possible to record 150 or more music files per CD. Therefore, if a static one-dimensional array is used as a basic operation target as in a conventional audio player and music is selected by music number or music name, a great deal of time is required.
An object of the present invention is to provide an audio player that pays attention to such inconveniences and makes it easy to understand the recorded contents of the entire disc and further reduces the time required for music selection.
