ABSTRACT:
A condition of a recording pulse comprising a top pulse and a following pulse is determined in a predetermined order. In some embodiments, an mT pulse condition is first determined by test recordings with various power and pulse conditions, involving an inspection of recording quality; then an m′T/(n−m)T ratio is determined by test recording under the mT pulse condition fixed; and finally an nT pulse is configured based on the ratio. A phase shift can be corrected by test recording with the nT pulse.
