Problems solved by technology

[0007] However, there is a problem that the above-mentioned tilt adjusting device cannot adjust the tilt during playback, adjusts the surface that the turntable and the optical pickup path have before playback during production, cannot actively adapt to the curvature of individual magnetic disks, and, in In the case of adjusting the guide rod up and down, although the optical reader moves obliquely while adjusting the tilt, if the driving source of the optical reader that requires fine adjustment passes through the inclination of the guide rod, an overload occurs, causing the Reduced optical readout shift characteristics, thus affecting playback characteristics
Also, the manual adjustments made limit the fine-tuning

Abstract

An inclination regulator for magnetic disc player features that according to the curved state of the record surface on magnetic disc the cam unit and the regulating plate are driven to rotate by a bidirectionally rotary motor to regulate the inclination of turntable. It is composed of desktop, optical reader element moving radially above magnetic disc and emitting optical beam onto said record surface, regulating plate, motor, turntable, and rotator to rotate regulating plate.

Description

technical field [0001] The present invention relates to a disk player, and more particularly to a player tilt adjustment device capable of adjusting the tilt even during disk playback according to the curvature of the recording surface of a disk placed on a turntable and rotating at high speed. Background technique [0002] The disk player is driven by the loading mechanism, and the disk such as the digital disk (Compact Disk) or the digital video disk (Digital Video Disk) is loaded on the turntable, clamped by the action of the clamping unit, and the radial direction of the disk is made by one side While reciprocating, the drive of the optical pick-up unit (optical pick-up unit) radiated on the recording pit (pit) of the magnetic disk is used to reproduce or record the information on the magnetic disk. [0003] In order to replay or record the information on the disk, since the beam emitted in the optical reading element is required to be irradiated on the recording pit of ...
