ABSTRACT:
An address data accessing device is used with a reproducing apparatus which reproduces recorded signals from a rotary recording medium which is time-sequentially recorded with a plurality of kinds of information signals, a time address signal, and a chapter address signal. The address data accessing device comprises an instruction decoder supplied with an information signal selecting instruction data when selectively reproducing one kind of information signal from among the plurality of kinds of information signals which are reproduced from the recording medium, an address data fetch circuit for fetching and producing one of the time address signal and the chapter address signal which are reproduced, and a switch circuit for switching and producing one of an output signal of the instruction decoder and a signal from the address data fetch circuit in response to another output signal of the instruction decoder, and for applying an output signal thereof to the address data fetch circuit. The address data fetch circuit alternately fetches and produces the time address signal and the chapter address signal under control of the output signal of the switch circuit.
