Abstract
PURPOSE: To increase operation tolerance by simplifying a write control circuit by providing a housekeeping group generator in a housekeeping group.
CONSTITUTION: Generator 11 dedicated to a housekeeping group is provided independently of data loop generator 10 and magnetic bubbles are generated on the basis of fixed curent pulses by hair pin contactor pattern 101 and part of asymmetric chevron permalloy pattern 102. New data are written direct to housekeeping group 31 by generator 11. Read operation is performed by detector 60 via gate 41 and transfer line 53.
