Patent ID: 7769946

Claim:
An information processing apparatus for reproducing an audio-only disk-shaped recording medium, said apparatus comprising: a disk receiving means for receiving at least the audio-only disk-shaped recording medium; reproducing means for reproducing an audio data signal from said audio-only disk-shaped recording medium; storing means for storing data; and controlling means for controlling reproduction of audio data from said audio-only disk-shaped recording medium on the basis of control information stored in said storing means; wherein said controlling means controls the reproduction of said audio data on the basis of system controlling software stored in said storing means, said controlling means configured to provide: an application layer for converting a request from application software into a predetermined command and outputting the predetermined command, wherein the predetermined command is independent of a type of file system being used; and a driver layer having a file system layer including a virtual file system and an audio-only file system, wherein the virtual file system receives the predetermined command from the application layer, determines a corresponding control command for the audio-only file system, and outputs the corresponding control command to the audio-only file system which outputs the received corresponding control command to a device driver in a device layer for said reproducing means to read the audio data from said audio-only disk-shaped recording medium, and to control the disk receiving means corresponding to said corresponding control command.
