PURPOSE:To reproduce a play which is started again with application of a power supply right after the play performed before discontinuation by storing the data on the process of the play and deciding the play that is restarted after the discontinuation of the play based on said data. CONSTITUTION:A function which performs a play again right at the position performed before the discontinuation of the play is considered together with a function which continue the play of the precedent program supplied and operated In such a case, the minimum necessary data to be stored in a semiconductor memory 18 requires the time information (last time information) showing the position that is so far reproduced, the information (program information) on the procedure of the program play and the information (pointer) showing the number of music that is reproduced during the program play. It is unknown that when the power supply is cut off for the last time and the pointer. Therefore it is necessary to read frequently the latest information out of a disk and transfer it to a semiconductor memory 18. For this purpose, a system controller 14 is used. The memory 18 is also used to store data when the proper power supply is given to a player. This eliminates the necessity for the save of the data. |
