ABSTRACT:
There is provided a high-availability duplexing or multiplexing information recorder where a process is not interrupted by a trouble of a drive or a medium. The information recorder is directed to write data instructed to be written from a host system in recording media of at least two drives. The recorder is configured to: detect an abnormality of each drive itself and an abnormality of the recording medium of each drive; cancel the writing of the data in the recording medium of the drive where an abnormality is detected or the drive having the recording medium where an abnormality is detected; and continue the writing of the data in the recording medium of the following drive without notifying any abnormality to the host system, as long as there is at least one drive where any abnormality is not detected and which has the recording medium where any abnormality is not detected.
