有している。As mentioned above, in the magnetic head assembly of a conventional magnetic disk device, the part where the arm that holds the magnetic head and the housing that holds the arm come into contact is formed of aluminum casting that has been colored and chromated. When the magnetic disk drive is assembled into a housing, the arm and the housing rub against each other, which scrapes the surface of the arm and generates dust, which contaminates the inside of the magnetic disk drive and causes trouble.

を向上することができるという効果がある。As explained above, in the magnetic head assembly of the present invention, the part of the arm that holds the magnetic head that comes into contact with the housing is hardened, so that the arm and the housing will not rub against each other when the arm is assembled into the housing. Even though
This has the effect of preventing dust from being generated due to scraping of the surface of the arm, thereby keeping the inside of the magnetic disk drive clean and improving the reliability of the magnetic disk drive. There is.
