OPTICAL SWING ARM OF A MICROMINIATURE OPTICAL DISK DRIVE, SPECIALLY IN CONNECTION WITH SEPARATING A BASE OPTICAL UNIT FROM AN OBJECTIVE LENS END TO THINLY FABRICATE AN OPTICAL SYSTEM

摘要

PURPOSE: An optical swing arm of a microminiature optical disk drive is provided to integrate an optical system through a base optical unit, and to separate the base optical unit from an objective lens, thereby very thinly fabricating the optical system while realizing an optical flying head having an air bearing surface unit for focusing, consequently a space occupied by a actuator can be remarkably reduced. CONSTITUTION: A swing operation arm(320) is hinge-coupled with a drive body. A VCM(Voice Coil Motor)(400) generates a driving force in connection with a rear section of an optical swing arm(300). A suspension assembly(360) is fixed to the operation arm(320). An optical flying head(350) consists of an MEMS(Micro Electromechanical System) actuator and an objective lens for compensating for an assembling error. A base optical unit(330) is installed on the swing operation arm(320). A folding mirror controls a path of a beam incident from the base optical unit(330) and the optical flying head(350).
