Abstract
An audio playback device is provided which can play back recorded audio data in an operational mode that is more convenient for the user. With a DVD-Audio disk 1 mounted, a navigation manager examines whether or not the DVD-Audio disk 1 includes an ASVSI file, that is, whether or not the DVD-Audio disk 1 includes a still picture to be displayed together with the audio data. Also, the navigation manager examines whether or not an AMGM_VOBS file exists in the DVD-Audio disk 1, that is, whether or not the DVD-Audio disk 1 includes a visual menu. When a still picture or visual menu is not included, a player mode is set to an AOP mode in which the still picture is not played back, while in other cases, the player mode is set to a VCAP mode in which the visual menu or visual contents can be played back and displayed.
