Abstract
An apparatus comprises a moveable arm for positioning an optical transducer adjacent to a storage medium, a stationary light source, and a moveable mirror mounted at a pivot axis of the arm for reflecting light from the light source to the optical transducer. An actuator can be provided for rotating the moveable mirror through an angle of about one half of an angle of rotation of the moveable arm.
Claims20
An apparatus comprising:
- a moveable arm for positioning an optical transducer adjacent to a storage medium;
- a stationary light source;
- and
- a moveable mirror mounted at a pivot axis of the arm for reflecting light from the light source to the optical transducer.
1 more element
An apparatus comprising:
- a first moveable arm for positioning a first optical transducer adjacent to a storage medium;
- a second moveable arm for positioning a second optical transducer adjacent to the storage medium;
- a stationary light source for producing a beam in a direction along a pivot axis of the first and second moveable arm;
- a first mirror mounted at the pivot axis for reflecting light from the light source to the first optical transducer;
- a second mirror mounted at the pivot axis for reflecting light from the light source to the second optical transducer;
- and
- means for moving the first mirror away from the beam.
