MAGNETIC HEAD AND METHOD OF MANUFACTURING SAME |
摘要 |
The magnetic head according to the invention has a magnetic core (1, 2) with pole tips (3, 4) which limit a gap (5) which is filled with a synthetic resin chosen from the group comprising epoxy resins, acrylic ester resins and polyester resins as a non-magnetizable material which adheres the pole tips to each other. The gap has a length of at most 0.5 mu m. A modifier may be used at the interfaces between the synthetic resin and the pole tips (3, 4) to further increase the tensile strength. The magnetic head is manufactured by applying to a moulding (1) of magnetizable material a solution of synthetic resin, by rotating the moulding about an axis at right angles to the coated surface and by placing a second moulding of magnetizable material (2) against it and curing the synthetic resin under pressure at an elevated temperature. |
