PURPOSE:To display securely a highly-advanced control function with simple constitution and to improve the operability by providing a disk specifying means and a search command means for searching an address corresponding to data to be reproduced on one disk with respect to a disk reproduction drive means in the prescribed direction. CONSTITUTION:The presence and absence of the operation of an up-key 131 is judged. When it is YES, a value Q in a RAM213 is added to one. The comparison and judgement are made whether or not said value is larger than the maximum musical program on a disk A. When the judgement is YES, that is, the value Q added to one is larger, a disk (disk B) mounted on a disk B mounting part 111 is brought into the reproduced and driven state, after which the minimum musical program on the disk B is stored in the RAM213 as a new value Q. After it is read out to set it to a search address, the search action with respect to the search address is started, and judgement is made whether or not the search action is terminated. When the judgement is NO, the search action continues. On the other hand, when the judgement is YES, the search action is shifted to the reproduced state, after which the necessary key operation is waited. |
