ABSTRACT:
A housing assembly for magnetic head supporting arms of a magnetic disk device includes a housing which has a cylindrically shaped through-hole having two bearings each provided at each end of the through-hole and is formed integrally with supporting arms for supporting magnetic heads. The housing has a cylindrically shaped collar which is constituted by a member having the same linear expansion coefficient as that of the bearings and is fitted between the bearings in an exact fitting dimensional relationship with the bearings. The housing has a slit which extends through an entire axial length and is disposed in a wall defining the through-hole of the housing. The thermal strain in the head supporting arms integral with the housing can be suppressed so as not to be influenced by a temperature rise of the device or a temperature change of environments.
