Abstract
In a disk player, upon the lock-in of the focus servo at the turn-on of the main power source, the information recorded on an information recording disk is read and the sub-code information such as frame numbers, time code, or the like which are obtained from the read output are set to fundamental information for generation of random numbers in the random play mode, so that the initial value for the random numbers is set at random. The programs can be played in accordance with the different sequences even for the same disk. A preferable random-play control can be performed.
