PURPOSE:To quickly select and reproduce desired information, by detecting an address from a reproducing signal recording program information together with address data and designating a desired address. CONSTITUTION:An address recorded together with information is read out at a head 3 from a disc 1 and light is received 4, wave shape and A/D conversion 5 are performed and decoding 6 is done to transmit information S. On the other hand, the decoder 6 detects address data QN stores it in a register 7 and the address data QN of the information during reproduction at present is applied to a key input operation section 8 and a system controller 9 in a specified timing. A forward code Ku or a reverse code Kd is outputted through the operation of program selection keys 10, 11, operated 8 and a code Qx is inputted to a system control section 9 via a register 14. A control signal Sc is outputted and a head 3 is driven 15. Thus, the selection keys 10, 11 are operated until desired information is obtained to select the information quickly. |
