Abstract

PURPOSE:To know the state of the off-line collecting information before a central processing action, by printing and recording the number of all blocks, the number of blocks where the normal recording is carried out, etc. after reading all information that is recorded in division with every block and in numerical order. CONSTITUTION:The information divided with every block in numerical order are successively read out of a magnetic recorder/reproducer 12 under the process control carried out by a CPU11 based on the program of an ROM15 and in accordance with a checking instruction given through a keyboard 13. Then the abnormal recording or normal recording is decided, and the result of this decision is written into an RAM30 including various types of regions such as a full data number counter regions 31, a normal data number counter region, etc. Based on the contents of the RAM30, all block number and the normal recording block among the all blocks or the abnormal recording block number are recorded by printing to be collected in an off-line system. Thus the state of the information collected in such way is known before a central procession.
