    • An apparatus and a method of determining an optimal writing power for an aged writable disk after checking whether a writable disk is aged or not, are discussed. The apparatus and method according to an embodiment read signals written on a writable disk, judge whether or not the writable disk is aged based on a signal characteristic, e.g., a level difference between the read signals before and after an equalization and jitter of the read signals, and conduct an OPC for the writable disk to obtain a precise optimal writing power if the disk is judged to be aged. The precise optimal writing power can prevent deterioration of reproduction characteristic of recorded data even though an aged writable disk is used.

    • A method of recording data onto an optical disk uses a write strategy that corresponds to the recording features of the optical disk. The method detects a track pitch or storage capacity of a recording medium, adjusts a write strategy according to the detected track pitch or storage capacity wherein the write strategy has been chosen to correspond to the manufacturer of the recording medium, and records input data onto the recording medium using the adjusted write strategy. Accordingly, data quality during later reproduction is improved even though it is recorded onto a non-standard disk that is larger in capacity than the standard.
    • 将数据记录到光盘上的方法使用与光盘的记录特征对应的写入策略。 该方法检测记录介质的轨道间距或存储容量,根据检测到的轨道间距或存储容量调整写入策略,其中已经选择了写策略来对应于记录介质的制造商,并将输入数据记录到 记录介质使用调整后的写入策略。 因此,即使将其记录在容量大于标准的非标准盘上,后期再现期间的数据质量也得到提高。

    • An apparatus includes a controller storing information on dense/sparse state of the tracking error signal in connection with characteristic of the signal generated by a phase encoder while tracking servo of a servo unit is inactivated, and, in data reproduction mode, identifying a current disk phase based on characteristic of the signal generated by the phase encoder, and adjusting tracking characteristic of the servo unit based on the stored information in connection with the signal characteristic in order to compensate an effect rate of eccentricity on the identified disk phase. Through minute adjustment of servo characteristic for each disk phase, error range of TE signal to track in real time is reduced. Therefore, tracking for an eccentric disk becomes easier and more reliable.
