Abstract

PURPOSE: To increase the speed of the continuous information reading time by specifying the relation of the inter-face magnetic field cycle or the like at the operating time of the minor loop, major loop and transfer gate.
CONSTITUTION: M-units of minor loop 2 are provided every n-bits of major loop 1, and each minor loop 2 has the bit capacity of Nm. Then the bit space is referred to as l between entrance and exit 32 and 34 of loop 1 side of transfer gate 3, the bit space is h between entrance and exit 31 and 33 of loop 2, the rotary cycle is g2 for the inter-face magnetic field which shifts the magnetic bubble from loop 1 to 2 at the operating time of gate 3, and rotary cycle is g1 from loop 2 to 1 respectively. When the page number is set to K for the information which can exist simultaneously in loop 1, the constitution is given so that the relationship between Eqs. I and II may be satisfied. In this way, the page space on loop 1 can be minimized, thus realizing the high-speed reading for a large amount of information.
