摘要:
Each of record information blocks in various modes is divided into predetermined information units each having a head indicator indicating a head of respective one of the predetermined information units. An information recording apparatus, to which the record information blocks are inputted in time sequence for each of the modes, is provided with: an emulation device for emulating the predetermined information units one after another; an indicator memory device for temporarily storing the head indicator in a current information unit, which is one of the predetermined information units and is currently emulated by the emulation device, for a time duration while the current information unit is emulated; an update device for updating the head indicator, each time when an emulation for the current information unit is completed by the emulation device; and an error judgment device for judging whether or not an error is generated during the emulation for the current information unit. The emulation device re-emulates the current information unit, which is indicated by the head indicator stored in the indicator memory device, by use of one emulation method, which corresponds to a mode of the record information block including the current information unit and is different from another emulation method which has been used hitherto by the emulation device, when the error is generated according to a judgment by the error judgment device.
