Popis:	Write strategy optimization is desirable for expanding system margins. However, this process is very complex and time-consuming. We propose one-path calibration method of write strategy using simultaneous linear equations for Blu-ray disc. In this method, write pulse compensation on mark deviation is expressed clearly by two simple linear equations. Experimental results using these linear equations show that the write strategy is optimized after only one-path test recording. Thus, with the new method, it is possible to reduce the number of test recordings and to save test recording areas.
