Abstract
According to one embodiment, a disk device includes a first actuator assembly and a second actuator assembly which are respectively supported by a first bearing unit and a second bearing unit to be rotatable about a support shaft. The first bearing unit includes a first sleeve and a ball bearing. The second bearing unit includes a second sleeve and a ball bearing. The first sleeve includes a first end surface opposed to the second sleeve and an annular first step projecting from the first end surface, and the second sleeve includes a second end surface opposed to the first step with a gap and an annular second step projecting from the second end surface. The second step is opposed to the first step and the first end surface with a gap.
Claims8
A disk device comprising:
- a rotatable disk shaped recording medium;
- a first actuator assembly including a first actuator block rotatably supported on a support shaft via a first bearing unit, a suspension assembly extending from the first actuator block, and a first magnetic head supported by the suspension assembly;
- a second actuator assembly including a second actuator block rotatably supported on the support shaft via a second bearing unit, a suspension assembly extending from the second actuator block, and a second magnetic head supported by the suspension assembly;
- and
- a seal structure located between the first actuator block and the second actuator block and configured to suppress leakage of lubricant from the first and second bearing units.
