Abstract

PURPOSE: To adjust a bias magnetic field supplied to a bubble memory chip surface with use of a magnet by providing through holes for connecting a shield pattern and a pattern for an earth formed on a peripheral surface of a ceramic plate of the rear side on a printed circuit board and its rear side ceramic plate.
CONSTITUTION: Shield pattern 2a, 2b formed on a ceramic plate 1 of the first layer and shield patterns 11a, 11b formed on a ceramic plate 10 of the third layer are connected by through holes 3aW3c and the shield pattern 11a, 11b formed on the ceramic plate of the third layer are connected to a pattern 8 for an earth through through holes 9a, 9b. Thereby, the shield patterns 2a, 2b, 11a, 11b performing a magnetic shield with respect to a vertical component generating a driving coil for a rotating magnetic field are used also as the pattern for the earth, so that a whole of the package is made compact and a vertical magnetic field generated in the driving coil can be made small by a magnetic shield effect.
