PURPOSE:To speed initialization access to a magnetic bubble by specifying one minor loop as a marker loop and by providing a replicate transfer out gate which corresponds to said loop. CONSTITUTION:A specific minor loop 1c is set as a marker loop and information 1 is written to only the marker bit 1c1 of the loop lc. This information is read by a characteristic replicate transfer out gate 10 arranged closely to a detector 3 to perform n-bit transfer, so that the marker bit 1c1 is detected by the detector 3. For this purpose, when defective information is written in a page address leading the bit 1c1 by (n) bits, defective loop information is read out shortly after marker detection to speed initial access to a magnetic bubble without requiring complex constitution. |
