Optical disk apparatus

Abstract

Within an optical disk apparatus of slot-in type, having a traversing mechanism portion 5, which mounts a disk motor 2, a turntable 2a and an optical pickup 3, etc., thereon, being attached on a chassis 4 building up a housing of the apparatus, and also an elevating mechanism for brining an optical disk to be chucked on the turntable when loading it, there is further provided height adjusting mechanisms or members 200a and 200b are provided at two (2) positions on a supporting axis line of the traversing mechanism and the position coming off that, thereby making the traversing mechanism adjustable with respect to the chassis, when the apparatus performs recording/reproducing operation thereon. Therefore, there is provided the optical disk apparatus, generating no abnormal sound due to contact of the optical disk with a part of housing of the apparatus when it is in the position for recording/reproducing operation, in spite of thinning in the thickness of the housing of the apparatus.
