ABSTRACT:
A memory device includes a head arm assembly which is movable in the radial direction. A flat coil is provided at an end of the head arm assembly, with a yoke arranged to surround the flat coil. A magnet is arranged on the yoke to administer a magnetic force to the flat coil. A base has an external circumference wall to form a space to accommodate at least the magnet, a memory medium, the head arm assembly, and the yoke. The base further includes a height setting surface provided near the wall of the drive space to oppose the yoke. The yoke is arranged on the surface by engaging with the surface.
