Abstract
A system and method of controlling data recording process of optical recording medium in a sequential writing are described. The control system comprises an information unit, a data-preparing unit and a recording controller. The information unit generates an information signal. The data-preparing unit prepares the data for recording. The data is then transformed into a writing signal according to the information signal. The recording controller controls the data-preparing unit to adjust the writing signal while acquiring the information signal during a sequential writing. Thus, the recording controller adjusts the writing signal according to the information signal. The data-preparing unit outputs the adjusted writing signal having desired recording area and undesired recording area and the adjusted writing signal is recorded on the optical recording medium during the sequential writing. The adjusted writing signal is outputted to OPU. The OPU performs a recording process of the optical recording medium.
