Abstract

PURPOSE: To surely find the defect of a transfer pattern by repeating the stop and restart of the rotating magnetic field at every access of address of arbitrary number of plural loops adjacent to each other.
CONSTITUTION: In the case where the nth loop data are all "1" and the data of the (n-1)th loop and the (n+1)th loop which are adjacent thereto are all "0", and in the case of the reverse, the test pattern is written and every access of address of arbitrary number the stop and the restart of the rotating magnetic field HR are repeated and through a defect transfer pattern, the movement of the bubble to the adjacent loop or the abnormal operation is promoted. By reading out these data, from the loop to be "1" data loop, "0" is detected, and reversely from the loop to be "0" data loop, "1" is detected to surely detect the range of defect.
