A low cost, low power, lightweight, low audible noise, high speed actuator for a read and/or record implement or portion thereof attached in a structure with a free end which is movable in multiple directions about essentially a single point of a pivot. In close proximity, the free end preferably moves along a mostly stationary, partially spherical media having its center point at said single point. An actuator can be devised with very low inertia whereby most of the read and/or record implements are attached to a support. Also, focus and/or tracking implements could be essentially stationary in respect to said structure so that the actuator may require only one member to be movable with only one contact point coupling said structure and support. Possible no conventional flex lead may be required. Optionally, precision of focus and/or tracking implements may be enhanced by translation. |
