PURPOSE:To obtain a format generating circuit by a simple circuit, by controlling the driving of a multiplexer, etc. by a read-out output of a storage device. CONSTITUTION:For instance, a counter CT1 is preset so as to designate an address (n) of a storage device ROM. An output B of the storage device ROM controls a multiplexer MPX, selects a data DATA, outputs C, D control information passing through FCC and CRC circuits, and an output E controls a modulating circuit MOD. In this state, when for instance, 16 is outputted from the output, an address (n)+1 is designated, the operation is shifted, for instance, to write control of a section mark part of a stripe, and thereafter, when it is executed repeatedly in the same way, a format can be generated. In this way, a format generating circuit can be obtained by a simple circuit. |
