Method for producing a magnetic head, the magnetic head including a pair of magnetic core halves |
摘要 |
Method for producing a magnetic head of a pair of magnetic core halves combined with a nonmagnetic layer therebetween including forming a winding window in at least one of a pair of generally flat oxide magnetic plates, forming at least one underlying layer on each oxide magnetic plate, forming a metal magnetic thin film on the underlying layer containing magnetic crystalline particles having average volume Va and average surface area Sa fulfilling the relationship Sa>about 4.64 Va¾, forming a groove in a body including the oxide magnetic plate, underlying layer and metal magnetic thin film, and combining the body with another body including an oxide magnetic plate and a metal magnetic thin film with a nonmagnetic layer therebetween, where the metal magnetic thin film is formed in such a manner to prevent the oxide magnetic plates from cracking due to internal stress generated in the metal magnetic thin film.
