PURPOSE:To improve the quality of signal record by preventing the fluctuation of the output of the recording laser beam due to eccentricity of the disk. CONSTITUTION:In a record enable magneto-optical disk device controlling the output of the recording laser beam corresponding to at least the radial position of the opto-magnetic disk, the signal displaying the radial position of the information recording track of the relevant magneto-optical disk is transferred to a monotonic increase signal or a monotonic decrease signal with a signal holding circuit means and based on the signal the setting of the output of the recording laser beam is conducted. As the signal holding circuit means, for example a peak hold circuit, a bottom hold circuit or a mean value circuit, etc., can be used. |
