Abstract

PURPOSE:To reduce initializing time, by providing a page mark storage loop and page address storage loop in a plurality of minor loops, and writing in a plurality of marker bit information or address information respectively. CONSTITUTION:Magnetic bubbles generated in a loop of conductor pattern (broken lines) constituting a generator 4 are given to a minor loop 2 via a major loop 1. In this case, a marker bit 8 of a page mark bit 8 of a page mark storage loop 21 is referenced. Further, an address 9 of an address storage loop 22 is referenced. Thus, the address information corresponding to the address 9 is written in a location corresponding to the marker bit 8 to each minor loop 2. A plurality of marker bits are stored on the loop 21 with an arbitrary interval, and the operation is finished in the interval time of the marker bit at initializing, allowing to reduce the initializing time.
