PURPOSE:To improve the start/stop characteristic by molding a permanent magnetic plate and a magnetic adjusting plate so as to give a tilt angle theta prior to the total mold thereby forming the tilt angle of the base accurately. CONSTITUTION:A magnetic bubble memory element 3 is mounted on the base 4 and a solenoid coil 5 is mounted to the outer face. A plane having a fixed tilt angle theta is formed to a face corresponding to the plane of the magnetic bubble memory element 3 at both outer faces of the base 4, and a magnetic block assembly 9 formed by molding the permanent magnet 1 and the magnetic adjusting plate 2 with a transfer mold resin 6 at the opposite side is arranged oppositely so that the tilt faces are in parallel mutually and the base 4 is constituted with a fixed angle theta of tilt. Through the constitution above, the outer face of the solenoid coil 5 mounted to the base 4 is clipped by the tilt face side of the magnetic block assembly 9. Thus, a fixed tilt angle theta is given to the base accurately and easily. |
