Abstract

PURPOSE:To realize a high-speed read and high density by simplifying the detection of the continuous data pattern of a line of magnetic bubbles, by arranging a detector and expander arranged in on a fixed relation. CONSTITUTION:Magnetic bubbles transferred are expanded by chevron expander 10 to 2960mum; when they reach detector 1, the upper-end magnetic wall of a magnetic bubble is expanded 20mum upper than that of an adjacent bubble positioned at expander 11 one bit before, and the lower-end magnetic wall 20mum lower. Therefore, 20mum-expanded parts are hardly influenced by a leaking magnetic field from a following magnetic bubble one bit before, and magnetic bubbles at detector 1 are stably expanded and held.
