Abstract
PURPOSE:To allow a random number to be enough random and further, a music order to be enough random by generating the random number by using the present position information of a pick-up and the counting value of a counting circuit as an initial value. CONSTITUTION:A signal recorded to a disk is extracted by an optical pickup device 1, the reproducing signal of the optical pickup device is processed by a signal processor 2 and the present position information and a digital music signal are extracted. On the other hand, a counting circuit 3 adds an internal counter at every fixed period regardless of a disk signal. A random number generator 4 generates the random number by using the present position information and the value of the counting circuit as the initial value and an optical pickup driving device moves the pickup to the position of a music designated by this random number. Thus, since the value of the special initial value does not exist in the operating method of the random number generator, the generated random number is made enough random and thus, the music order can be made enough random.
