APPARATUS AND METHOD FOR CONTROLLING OPTICAL DISK RECORDING POWER

Title:

APPARATUS AND METHOD FOR CONTROLLING OPTICAL DISK RECORDING POWER

Document Type and Number:

Japanese Patent JP3778119

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To calibrate an over-drive power level with a simple configuration.
SOLUTION: A main control section 15 allows an over-drive power generation section 14 to make an over-drive power current zero, sets a desired over-drive power level to an object value, and while a base power control section 13 controls a base power current, the main control section 15 allows the over-drive power generation section 14 to increase the over-drive power current until the base power level monitored by a base power level monitor section 11 is coincident with a desired base power level when the base power level monitored by the base power level monitor section 11 is coincident with the object value.
