Abstract

This article describes a full-access coil form for a magnetic bubble package. The magnetic bubble package consists of a coil form for drive field and orthogonal coils oriented to permit core access at opposite ends. By winding coils 11 and 12 at a 45 degree angle with respect to the longitudinal axis 13 of the bobbin form 14, openings are created at opposite ends 15 and 16 of the coil structure. The forward opening 15 facilitates insertion of a bubble domain device/carrier 17, while opening 16 accommodates a connector plug 18 that provides all necessary electrical functions on device/carrier and coil leads.
