ABSTRACT:
An information recording method and system for writing information onto a recording medium. If an error area is detected in a check of the information read out of the medium after writing, the information is rewritten onto an alternative area on the recording medium using a buffer memory while the information in the error area is kept valid. Loss time accessing the alternative area is eliminated until the error checking and correction in the error checking and correction circuit is not available for the information read out of the error area through a reading circuit.
