PROBLEM TO BE SOLVED: To make pieces of specified music of disks specified by a user to be continuously reproduced from leading parts instantly and without interrupting information even when the exchanging of disks is needed as to many pieces of music while using a memory having a small capacity. SOLUTION: At the time of initializing a system such as the time of supplying a power source to the system, data of leading parts of pieces of music are read out from respective disks and the data are compressed in a data compressing circuit 41 to be stored in a leading part memory in a memory block 12. After initialization, when a certain music of a certain disk is being reproduced, in the case a user requests the reproducing of a certain music of a different disk, at first, the leading part data posterior to the compression of the specified music of the disk specified by the user are read out from the leading part memory and the data are expanded by a data expanding circuit 44 to be outputted. In parallel with this, the disk specified by the user is loaded on a player box and data following the leading part data of the music specified by the user are read out to be written in the main memory in the memory block 12 and the following part data are read out from the main memory after the leading part data posterior to the compression are all read out from the leading part memory.
