Title: Objective lens driving device
Inventor: MIYAJIMA GIICHI
IPC: G02B7/02
Filed: 1990-05-01
Abstract: PURPOSE:To substantially suppress the infiltration of dust and to secure the input/output of a normal optical signal extending over a long period by forming an optical window provided on an actuator cover as small as possible within a range not applying restriction on an optical function. CONSTITUTION:An optical window 8 opened at a recording medium side is formed while approaching the recording medium 7 side so as to secure the effective length in the tracking error correction direction of an objective lens 1 by an objective lens holder 2 and also, to attach effective width to secure the spot diameter of a laser beam in a tracking direction. Therefore, the substantial aperture area of the optical window 8 at the recording medium 7 side can be remarkably reduced compared with a conventional one, and since the optical window 8 is approached to the recording medium 7 as closely as possible, the air flowing rate traversing the optical window 8 can be reduced, thereby, the amount of air infiltrating via the optical window 8 can be reduced, which remarkably reduces the infiltration of the dust. In such a manner, it is possible to suppress the stain of an optical system substantially and to secure the input/ output of the normal optical signal extending over the long period.
