PROBLEM TO BE SOLVED: To enable multi-track playing or multi-channel reproduction by reading out interleave data from a medium, storing temporarily them in a buffer memory, and reading out in parallel each data of plural kinds constituting basic interleave data from the buffer memory. SOLUTION: Basic interleave data circulating and selecting in order of an interleave data unit data channel is formed. Music data including a header part and an interleave part is supplied to a data recording device from an interleave device. A CPU 21a specifies a music address of a CD-ROM device, commands signal reproduction, and performs take-in of data. When a header part of music is read in the prescribed memory region, control parameters such as the number of channels of header information and the like is set to DSP of a voice processing section 21e. An interleave data part of a music file is read with a block unit of a buffer memory, and it is transferred to a CD-ROM buffer, a main memory buffer, and a sound memory.
