Abstract

PURPOSE: To improve the reliability of recording content by providing a rewrite means recording a read data into an alternative sector when the counted value of attribute area and data area is respectively a set threshold value or over at the time of reading a recording medium.
CONSTITUTION: As the result of comparison by comparator circuits (1) 16, (2) 17, either or both the attribute and data areas in a reading state, if the number of errors corrected and read by an error detection/correction circuit 8 is a set threshold value and it is sent to a host interface 3, a CPU 1 stores a data in the read data area into other sector and alternative sector. If a read error exceeding its threshold value takes place to set a lower value than the correction capability limit to the threshold value, the data is stored in the alternative sector and it is possible to prevent the read error from exceeding the correction capability limit in advance. Thus, the reliability of data recorded in the recording medium is improved.
