Abstract

PURPOSE: To improve reliability of information by using an information comparing means to have comparison between the information read out of a disk device and the information read out of an information storing means.
CONSTITUTION: When a writing action and then a reading action are carried out, the information are read out simultaneously out of a disk device 2 and an information storing means 3. Then an information comparing means 5 compares the contents of the read-out information b2 with those of the read-out information b3. The information b2 is sent to a host device and at the same time the contents of the information b3 on the means 3 are checked. When no coincidence is obtained between both information b2 and b3, a signal showing discordance is outputted to the host device. Thus the host device generally carries out a retrial action.
