摘要： A magnetic bubble detector according to this invention is constructed of a bubble expander, a bubble detecting element and a bubble sweeper. Moreover, at least the width of soft magnetic material-elements constituting the bubble detecting element as taken in the propagating direction of magnetic bubbles is greater than that of soft magnetic material-elements constituting the bubble expander. As a result, the distances or distance between the magnetic bubble in the bubble detecting element and the magnetic bubbles or bubble in the bubble expander and/or the bubble sweeper increase or increases, so that a magnetic bubble detector of high signal-to-noise ratio is provided.

摘要： A magnetic bubble memory device according to this invention comprises a plurality of minor loops, a read-out major line is disposed at one end of the minor loops through gates having a replicating function, and a magnetic bubble detector which includes a detecting line is disposed at one end of the major line. Further, a propagation length from the other end of the read-out major line to the detecting line of the magnetic bubble detector is set at a bit length which slightly exceeds four times the number of the minor loops. For this reason, a continuous read-out operation at high speed is permitted without the influence of replicate pulses.

摘要： The magnetic bubble memory device of this invention is arranged such that a magnetic bubble detector and a nucleation type magnetic bubble generator in a chip are made to operate at different phases of the same operation cycle of a rotating magnetic field. Therefore, the operation time of the magnetic bubble detector and the operation time of the nucleation type magnetic bubble detector are completely separated from each other, although they are involved by the same cycle of operation of the rotating magnetic field. Consequently, the magnetic bubble detector can perform the detecting operation, without being affected by large amounts of noise which are generated during the operation of the nucleation type magnetic bubble generator.

摘要： Hydrogen ion is implanted twice or more at different acceleration voltages into desired portions of a magnetic film holding magnetic bubbles to form a magnetic bubble propagation path.

摘要： A Bloch line memory device and a method of erasing information in which, for erasure of a Bloch line pair representative of one bit of information and located in one end portion of one stripe domain, the stripe domain is stretched by decreasing the intensity of a bias magnetic field, an erasure Bloch line pair having a rotation of magnetization opposite to that of the to-be-erased Bloch line pair is injected into the end portion of the stretched stripe domain by supplying a current pulse signal to a conductor arranged substantially perpendicualr to the lengthwise direction of the stripe domain, and the stretched stripe domain is shrinked by restoring the intensity of the bias magnetic field, so that the to-be-erased Bloch line pair is combined with the erasure Bloch line pair to cancel the former.

摘要： A recording and reproducing apparatus including a recording magnetic head and a reproducing magnetic head with their floating height lowered for high density recordation and reproduction is provided. An information recording medium is provided on which it is possible to densely record information and from which it is possible to densely reproduce information by lowering the floating height of the recording and reproducing heads. The information recording medium includes a flat substrate and a recording layer provided on the substrate. Servo patterns and management information are recorded as magnetic marks on the recording layer in advance by a servo writer or the like. Because the substrate needs no recessed and embossed patterns formed in it, the slider of the recording and reproducing apparatus can be floated at a constant floating height lower than conventionally over the whole area of the medium. During information recordation, the position of the slider is controlled on the basis of the magneto-optical signals from the magnetic marks. During information reproduction, the reproducing magnetic head controls the slider position on the basis of the magnetic leakage fields leaking from the magnetic marks.

摘要： A magnetic recording medium (300) includes a substrate (1) and on the substrate (1) a first underlying layer (32), a second underlying layer (33), a magnetic layer (34), and a protective layer (35). Because of the existence of the first underlying layer (32) of Hf, initial growth layer having no specific crystal structure is prevented from growing in the second underlying layer (33). The second underlying layer (33) has a structure in which CoO particles having a cross section of a regular hexagon and separated by SiO2 portion are arranged in honeycomb. Since magnetic particles are epitaxially grown from CoO particles, the size of the magnetic particles and particle size distribution can be controlled, and the magnetic interaction between magnetic particles can be lessened. The underlying layer (33) and the protective layer (35) are formed by ECR sputtering. Such a magnetic recording medium is free from noise and thermal fluctuation, and ultrahigh recording density over 40 Gbit/inch2 is realized.
