Abstract
PURPOSE: To secure the full stretch even at such regions where the bias magnetic field is large, the rotary magnetic field is small land the frequency of the rotary magnetic field is high respectively by giving some contrivance to the pattern form of the magnetic bubble which is formed with the soft ferromagnetic thin film.
CONSTITUTION: The following patterns are used on the surface of the magnetic bubble medium: the chevron pattern which is formed aby connecting the 1st and 2nd element pieces sloping in the opposite direction to each other to the bubble transfer direction; the pattern which is based on the asymmetric chevron pattern and with the 1st element piece connected to several 2nd element pieces; and the pattern formed by mixing the patterns in which the 2nd element piece is connected to several 1st element pieces. As a result, the full stretch is possible at such regions where the bias magnetic field is large, the rotary magnetic lfield is small and the frequency of the rotary magnetic field is high each. Thus the characteristics can be improved.
