Rotary head actuator for optical disk |
摘要 |
A rotary actuator for an optical head comprises a pair of reflectors mounted respectively on the end of the arm and on the pivot axis to define an optical path via the arm to an optical disk for an external beam directed along the pivot axis. Special arm geometry reduces variable head skew and consequent image rotation. A multiple platter design features optical switches effectively aligned on the pivot axis.
