Abstract
A magnetic bubble memory device including a magnetic bubble chip of major-minor structure is disclosed in which an integer m prime to the number n of bits of a minor loop is selected from integers i satisfying an equation i=(2.sup..alpha. .+-.1).multidot.2.sup..beta. +1 or i=(2.sup..alpha. .+-.1).multidot.2.sup..beta., and logical addresses on the minor loop are assigned in such a manner that adjacent logical addresses are spaced apart from each other by m bits.
