Ceramic-ferrite head |
摘要 |
A ceramic-ferrite head for use with a flexible data-storage disk comprises a cylindrical body composed of magnetically soft ferrite and formed internally with a cup-shaped recess open at one end and a boss provided with a window at the opposite end. The core assembly is received in this boss and is bonded therein with a glass-resin composition while the coils of the assembly are found in the recess and are connected, together with the ground lead through a cap of the same material as the body, to a printed circuit board on the opposite side of this cap. The recess is lined with a conductive coating which is likewise grounded to the printed circuit board by the ground conductor.
