サーボドライバ電源電圧制御装置。[Scope of Claim for Utility Model Registration] A servo driver power supply voltage control device that controls the power supply voltage supplied to the servo driver of an optical disk player, which includes a scratch/vibration detection section that detects scratches and vibrations on the disk, and a device that detects scratches and vibrations on the disk, and detects scratches and vibrations on the disk. A monitoring unit monitors the start of braking and search, and normally supplies a low-level power supply voltage to the servo driver, and also monitors when scratches or vibrations are detected, when disc rotation starts, when disc rotation starts braking, or when search starts. A servo driver power supply voltage control device comprising a servo driver power supply circuit that occasionally supplies a high level power supply voltage to the servo driver.
