Claims

[Scope of utility model registration request]

In a disc-shaped recording medium reproducing device, comprising a spindle motor that rotationally drives a disc-shaped recording medium, and a servo motor that drives the optical pickup so that the optical pickup follows a recording track of the disc-shaped recording medium. , the rotational fulcrum of the spindle motor and the optical pickup is provided on a common substrate, and the physical characteristics are stable within the range of −30° to +80° C. between the spindle motor and the common substrate. , l An elastic material having good vibration absorption characteristics of kHz or less is disposed to block vibrations of the spindle motor caused by mass eccentricity of the disc-shaped recording medium from being transmitted to the optical pickup. Disc-shaped recording medium playback device.
