PROBLEM TO BE SOLVED: To improve responsiveness and reliability of a device when reproducing karaoke performance data such as BVG data. SOLUTION: An HDD3 and a DVD optical disk drive 4 are connected to an IDE bus 2. In the HDD3, data equivalent to one sector of the drive 4 are divided into equivalent to four sectors and stored. When a read write control section 15a reads data from the HDD3, a sector conversion section 15b is made to conduct a sector conversion to put together data equivalent to four sector data of the HDD3 and a control is made so that a data reading is made same as the data reading from the drive 4. |
