Abstract
Provided are a method of optical writing on a disc and a device adopting the method. The method of optical writing includes initially driving a laser diode (LD) at a preset reference value corresponding to a target output, detecting an actual output power by monitoring light output by the LD, and comparing the actual output power to the target output power. The method further includes compensating the reference value and writing data to the optical disc using the compensated reference value.
