Optical disk unit

Abstract

An optical disk unit which permits the operations of disk loading, disk rotation and pickup feeding with two motors, and which comprises, in order to make compatible the absorption of an external vibration and a restriction in vibration occurred due to turn-table rotation, a unit base (10), a traverse base (20) mounting thereon a turn-table (5) and a first motor (3) for driving it and an optical pickup (6) and its driving mechanism, and an intermediate base (80) disposed between the both bases, for supporting the traverse base via an elastic body so as to be vertically rotatable with respect to the unit base, the unit further comprising a power transmission path switching mechanism for switching the drive power transmission path of a second motor (4), for reversibly driving a loading drive mechanism and a pickup drive mechanism, between the two drive mechanisms, whereby a continuous, one-direction rotation of the second motor enables the approximately continuous operations of optical pickup moving, vertical turn-table moving and disk transferring in this order.

Description

technical field [0001] The present invention relates to an optical disc device for recording information signals on an optical disc such as a so-called CD (Compact Disc) or a so-called DVD (Digital Video Disc or Digital Versatile Disc) as an information recording medium and / or storing recorded An optical disc device for reproducing information signals (hereinafter, simply referred to as a disc device as appropriate). Background technique [0002] As such a disc device, it has been generally known in the past that the front panel of the device is provided with an opening for the disc tray to come in and out. A disk device with a structure that is introduced into a predetermined position inside the device (position for loading and unloading from a turntable). [0003] In this type of disc device, the optical disc introduced into the device is mounted on the turntable and rotated at a predetermined number of revolutions in a state sandwiched between the clamper, for example, d...

Problems solved by technology

[0022] However, there is usually some degree of deformation such as warping and bending on the surface of the optical disk. Corresponding to these deformations of the optical disk, the angle between the surface of the optical disk and the light beam must be more strictly specified. For the mechanism of moving the optical access device and the The disc clamping mechanism and the like need to be a very complicated structure
