Abstract
A digital audio recorder having a compact disk player for playing at least one compact disk having multiple tracks also has a hard drive and associated memory. The memory contains a database containing data relating to specific CD's such as album name, artist name, song title, and track, and may also contain playlists. The playlists can be loaded by the manufacturer or created by the user. There are correlations among the data. A central processor is connected to the compact disk player, the hard drive and associated memory, a second memory, display, audio output and buttons or knobs. Turning knobs or pushing buttons directs signals to the central processor and enables a user to operate the compact disk player, store in the second memory audio selections from a disk placed in the compact disk player, select and create playlists, and output audio selections contained in the second memory in an order according to a selected playlist. A keyboard communicates with the player through infrared signals.
