PROBLEM TO BE SOLVED: To improve operability at the time of reproductino by providing a rewriting means rewriting a management area so that the index numbers of respective pieces of data are changed in accordance with priority which is set by a priority setting means. SOLUTION: When CPU 32 judges the change of priority by an input signal from an operation part 50, it reads data stored in the management area (TOC) 9b of a flash memory 9. When priority is changed, CPU 32 drives a priority setting part and changes the priority value of pertinent sound data in TOC information of data which RAM 34 stores. The values of the priority and the index numbers of respective pieces of sound data which belong to sound data changed by driving the priority setting part and which are stored in a file are read. The index numbers of respective sounds are rearranged in order from the largest value of priority in accordance with a rule. CPU 32 drives the TOC rewriting part and rewrites TOC information. |
