ACTUATOR STOPPER AND STORAGE APPARATUS
According to one embodiment, an actuator stopper contacts a butting portion of an actuator which moves a head in a movement direction in a movement plane, and restricts a movement range of the actuator along the movement direction. The actuator stopper includes a first portion and a second portion. The first portion is configured to be positioned at an upstream side along the movement direction and contact the butting portion of the actuator. The second portion is configured to be positioned at a downstream side along the movement direction, have a smaller height than the first portion along a direction vertical to the movement plane, and be formed integrally with the first portion.
1 . An actuator stopper that contacts a butting portion of an actuator which moves a head in a movement direction in a movement plane, and restricts a movement range of the actuator along the movement direction, the actuator stopper comprising:
a first portion configured to be positioned at an upstream side along the movement direction and contact the butting portion of the actuator; and
a second portion configured to be positioned at a downstream side along the movement direction, have a smaller height than the first portion along a direction vertical to the movement plane, and be formed integrally with the first portion.
2 . The actuator stopper of claim 1 , wherein the first and second portions form a single member that has an inclined surface in at least one of upper and lower portions of a tubular or columnar member.
3 . The actuator stopper of claim 2 , wherein the single member has an opening, and a pin on a base where the actuator is provided is inserted into the opening to fix the single member.
4 . A storage apparatus, comprising:
a head configured to record information on or read information from a storage medium;
an actuator configured to hold and move the head in a movement direction in a movement plane; and
an actuator stopper configured to contact a butting portion of the actuator and restrict a movement range of the actuator along the movement direction;
wherein the actuator stopper comprises
a first portion configured to be positioned at an upstream side along the movement direction and contact the butting portion of the actuator; and
a second portion configured to be positioned at a downstream side along the movement direction, have a smaller height than the first portion along a direction vertical to the movement plane, and be formed integrally with the first portion.
5 . The storage apparatus of claim 4 , wherein the first and second portions form a single member that has an inclined surface in at least one of upper and lower portions of a tubular or columnar member.
6 . The storage apparatus of claim 5 , further comprising:
a base configured to allow rotation of the actuator,
wherein the single member has an opening, and a pin on the base is inserted into the opening to fix the single member.
7 . The storage apparatus of claim 6 , wherein the actuator stopper comprises:
a first actuator stopper configured to restrict a movement range of the actuator in a counterclockwise direction; and
a second actuator stopper configured to restrict a movement range of the actuator in a clockwise direction.
8 . The storage apparatus of claim 7 , wherein the first and second actuator stoppers have different sectional shapes.
9 . The storage apparatus of claim 5 , wherein the single member is formed of a material having flexibility.
