PURPOSE:To improve the slow reproduction of sub code information automatically by providing a repeating means repeating a sub code read by a read means to a decoding means in response to a repeating command. CONSTITUTION:When a slow reproduction is commanded, the frame number of a sub coding frame having been read is fetched and stored in the prescribed address of a RAM and when the read of a sub coding frame of a frame number stored in the RAM is finished, a switch 21 as a repeating means is turned off and a sub code is not relayed to a graphic decoder 22 and an MIDI decoder 23. Then when a time shorter than the time of one revolution of a disk by a prescribed time To elapses, the information read point of the pickup 3 is jumped by one track toward the outer peripheral direction. Thus, the sub code is supplied to a decoding means with an interval at each one block or plural consecutive blocks. Thus, slow reproduction is automatically improved. |
