Abstract: A music reproduction apparatus comprises an audio player and a headphone. The audio player comprises a circular main body, a display panel provided at a front face of the main body, an operating switch rotatably provided at a periphery of the display panel, and a wireless communication antenna provided at a rear face of the main body. The headphone comprises a circular main body, a speaker provided at one face of the main body, a wireless communication antenna provided at the other face of the main body, and an ear hook provided at the outside of the main body.

Abstract: According to one embodiment, in order to manage the remaining capacity of a secondary battery of an information recording/reproduction device, the remaining capacity of the secondary battery which supplies electric power to the whole device including a storage medium is monitored in accordance with current supply capacity and in accordance with voltage supply capacity. The remaining capacity is displayed on a display in accordance with the current supply capacity. The whole device is stopped when one of the current supply capacity and the voltage is below a system stop level indicating the electric power required on the startup of the storage medium.

Abstract: A playback apparatus including a playback unit which plays back audio information and the like, an accommodation unit which accommodates a detachable recording medium, and a controller. The controller causes the playback unit to access to the recording medium through the accommodation unit according to a first communication standard (PCMCIA) and causes an external apparatus to access to the recording medium according to a second communication standard (ATA) different from the first communication standard.

Abstract: In a reproducing apparatus for reproducing audio data, a central control section includes detection means for detecting playlists of plural kinds of formats, and detection means for detecting audio data not associated with playlists. The central control section reads out audio data from an audio data storage section, and discriminating the format of the audio data to detect playlists. In addition, the central control section detects the presence/absence of audio data not associated with playlists, and if audio data not associated with playlists is stored, processes a list of such audio data as one playlist. The central control section causes the detected playlists to be displayed on a display section, successively processes the audio data from a first one of the playlists, and outputs the processed data through a sound output section.
