Abstract

PURPOSE: To discriminate and indefectible minor loop and defective minor loop by setting a loop for defective loop write mark in minor loops to write a defect information position indication mark and reading out this mark in the information processing.
CONSTITUTION: When defect FL exists in minor loop LM,a defect information position indication mark is written in, for example, the first monor loop. Information of bubble absence and bubble presence are written onto defective minor loops and indefectible minor loops respectively, and the position of defect information is stored on LM. In a normal information processing, transfer gates TG are opened collectively to transfer information from LM to major loop LG in parallel, and information is transferred in LG and is read by detector DT. Since the defect information position indication mark is detected from the first LM, succeeding read information can discriminate an indefectible loop or a defective loop, and it can be decided whether the loop is used or not.
