Abstract

PURPOSE:To reduce the time of reading action, by previously storing both the error detecting sector number and the error information and performing an error analysis after reading all sectors. CONSTITUTION:Both the sector number and the error information are read out of a sector file channel (SFC) 3 when the reading is over for all indicated sectors. Then the error information is analyzed. If the error is correctable, the position of the corresponding error within a CCB10 is corrected based on the position of the error within a sector and obtained through an analysis and the data buffer address of a CCWB10. After the error correction, the error flag in a SFC3 is set at ''0'' to invalidate the contents.
