Abstract:
PURPOSE:To avoid the complication of a pulse generator by varying potential with respect to a magnetic wall by means of a micro area. CONSTITUTION:Stripe magnetic domain fixing means 21, 22... which are com posed of the strings of the micro areas 12 different in the potential for the magnetic wall are provided. The micro areas 12 are asymmetric with respect to a center line (a) along the array direction of the micro areas 12 and they are set to be point symmetry by 180 deg. on the center 0 of respective micro areas 12. The strip magnetic domain is generated in such a way that it surrounds the stripe magnetic domain fixing means 21, 22.... Since the potential with respect to the magnetic wall differs by the existence of the micro areas 12, a pair of Bloch lines (the inverse of VBL) can be set in a prescribed position and the waveform becomes asymmetric. Thus, the moving direction of a pair of the inverse of VBL is specified. Consequently, a pulse waveform for the shift can be set to a pulse having symmetry. Thus, the deterioration of a moving speed and the complication of the pulse oscillator can be prevented.

PURPOSE:To shorten an access time to desired page data by disposing a magnetic storing means having a minor loop for plural data and a minor lop for plural addresses and correspondingly page data and address information in the respective minor loops. CONSTITUTION:The magnetic storing means 5 having the minor loop 53B the plural data and the minor loop 53A for the address is disposed. The page data to which the address information supplied from an address applying means 3 respectively correspondingly to the minor loop 53B for the data and the minor loop 53A for the address is added is sequentially recorded. Accordingly, only by viewing the address information at the end of the minor loop, the corresponding page data can be recognized and the minor loop may be only circulated so as to bring the desired page data to the end of the minor loop. Thereby, the access time to the desired page data is shortened.
Abstract:
PURPOSE:To surely perform the write operation of information by small repulsion by performing the write of the information based on the presence/absence of magnetostatic repulsion between a bubble and the stripe magnetic domain of a minor loop ML. CONSTITUTION:The end part of the minor loop 1 consisting of the magnetic wall of the stripe magnetic domain is set at a first state to approach a write conductor 21 based on the presence/absence of a magnetic bubble on a major line 3 provided oppositely to the end part, or a second position state to traverse the write conductor 21. And the generation of a Bloch line is performed for only the minor loop 1 set at the first position state by energizing the write conductor 21, and the information due to the presence/absence of the magnetic bubble on the major line 3 is memorized on the minor loop. In such a way, it is possible to improve the certainty of the write operation and to compress an arranging area by rationalizing the arrangement of each part.
Abstract:
PURPOSE:To simplify constitution, and to enable high density recording by forming a strip magnetic domain, surrounding the stripe magnetic domain fixing means of a micro area, the potential against a magnetic wall of which is different. CONSTITUTION:When the stripe magnetic domain fixing means is formed by the train of the micro areas 12 constituted by an ion implantation, etc., which have the different potentials against the magnetic wall and the stripe magnetic domain to be a minor loop ML is formed surrounding it, the stripe magnetic domain comes into a waving shape because a distortion is generated in the direction of a film surface. Accordingly, the write-in of a information by a negative Block line pair is performed, a Bloch line is stably installed at the curved part of the minor loop ML, and a stripe magnetic domain position setting and the stabilization of the Bloch line by the area 12 are realized by the same constitution. As the result, the constitution comes simple, and the high density recording can be realized.
