ABSTRACT:
The magnetic disk unit has a cylindrical sleeve disposed between a plurality of bearings and an arm holder for magnetic heads rotatably supported by a head rotating shaft disposed in parallel with a disk rotating shaft for magnetic disks via the bearings. This sleeve forms a gap with the inner periphery of the arm holder to absorb a difference of thermal distortion in the radial direction of the arm holder and the bearings. Thus, thermal offtrack characteristics can be improved significantly.
