Abstract

PURPOSE:To discriminate the cause of error quickly and simply, by providing the checking means to check the normality of information and checking and discriminating the information read from the designated area on the medium. CONSTITUTION:When the head 2 is located on the same circle as the information storage area designated with the read instruction, the information is read one after another through the head 2 and amplifier 3. If the designated area is normally read, ''1'' is registrated in the register 8, and if there is any one area read normally other than the designated area, ''1'' is registrated in the register 9. Thus, the presence of read error and the factor can be discriminated from the content of the registers 8 and 9. That is, if the register 8 is at ''1'' and the output is at ''0'', it is normal, and if the register 8 is at ''0'' and the output is at ''0'', it is in failure. If the output of the gate 15 is at ''1'', it is regarded as failed medium and if the output of 15 is at ''0'', it is regarded as failed element. Thus, the causes to error can simply by judged.
