Abstract
PURPOSE: To prevent the drop-off of the block caused by the intermittence fault and thus increase the reliability, by storing previously the final record position into the magnetic disk or the like when the records are produced.
CONSTITUTION: The record writing is carried out in sequence starting at home address 31, and the head of each record is recorded by holding sequentially the number of the belonging sectors into register 11. Then the sector number of the final record is written in sector number 129 to produce the record of one track. If the intermittence fault occurs at the reading time, control part 4 starts the action of the fault end and then reads out the contents of number 129 to give it to register 8. Then the positioning is given again for the contents of register 11 based on the result of comparison 12 of the contents between registers 11 and 8. Thus the re- reading action is repeated. In such way, the drop-off of the block is prevented for the record.
