Abstract: The optical disk player is capable of writing data with optimum laser power corresponding to temperature. In the optical disk player, a laser diode irradiates a laser beam. A photo sensor detects light intensity of a reflected beam reflected from an optical disk. A processor controls laser power of the laser diode by a running optimum power control manner, in which the laser power is adjusted, on the basis of the detected light intensity of the reflected beam, to optimum laser power. A memory stores power correction values for correcting the laser power as a data table, in which the power correction values have been determined on the basis of temperature. The processor retrieves the power correction value from the memory and adds the retrieved power correction value to the present laser power of the laser diode in the case of increasing the laser power.

Abstract: A method of controlling a laser power of a zone Constant Linear Velocity (CLV) type optical disk player, in which a linear velocity of writing data is accelerated, by stages, toward an outer edge of an optical disk. The method includes changing a laser power for writing data onto the optical disk when the linear velocity is changed.

Abstract: The method of controlling laser power of an optical disk player, in which liner velocity of writing data is accelerated, by stages, toward an outer edge of an optical disk, is characterized in that a laser power for writing data is changed when the liner velocity is changed. With this method, the laser power for writing data is changed when the liner velocity is changed, so quality and reliability of the written data can be improved.
