PURPOSE:To prepare a complete data pattern for defective minor loop extraction by changing the number of transfer bits required from a bubble generator on a transfer line up to a bubble junction part. CONSTITUTION:A junction part 6 is fitted on the same address position of each minor loop, an auxiliary transfer line 7 is connected to the junction part 6 and a block generator 51 is attached on the transfer line 7. The number N of transfer bits required from the block generator 51 up to the junction part 6 is different in each minor loop. The number Ni of transfer bits on the auxiliary transfer line connected to the (i)-th minor loop is (Ni=2) and the number of transfer bits on the auxiliary transfer line connected to each of the (i+1)-th, (i+2)-th and (i+3)-th minor loops is increased by 2-bits successively. The magnetic bubbles generated at a time are inputted from the junction part 6 to each minor loop through the auxiliary transfer line 7 by being delayed 2-bits each. |
