Abstract

PURPOSE:To reduce the initializing time, by writing in a plurality of marker bit information to a page mark storage loop out of a plurality of minor loops, and storing the address information corresponding to the location in response to the marker bit to other minor loops. CONSTITUTION:Magnetic bubbles generated in a loop of a conductor pattern (broken lines) constituting a generator 4 are fed to a minor loop 2 via a major loop 1. In this case, a marker bit 8 of a minor loop 21 corresponding to the marker bit storage loop is referenced for initializing, and the address information corresponding to the location in response to the marker bit 8 of each minor loop is stored. On the loop 21, a plurality of marker bits are stored in an arbitrary interval, and since initializing is finished in the interval time of the marker bit 8, the initializing time is reduced.
