Ultra-small optical/magnetic head actuator with pivot hinge and Halbach magnet array

摘要: An ultra-small optical/magnetic head actuator includes: a swing arm movable in horizontal direction (tracking direction) and vertical (focusing having mounted thereon for reading writing information on disk. A tracking moves the pivot hinge adjusts radius of rotation guides movement direction. focusing direction), wherein includes coil attached under Halbach magnet array disposed minimizes thickness. Friction or backlash can be avoided, non-repetitive errors reduced. The thickness storage device reduced due to use array.
