    摘要： An optical information recording method for recording information onto an optical information recording medium is provided,
    wherein the optical information recording medium comprises a control track region storing information that represents a recording density,
    the method comprising:
    an identification step of identifying the recording density of the optical information recording medium; and
    a recording pulse correction step of correcting a recording pulse position, in order to form a recording mark in a predetermined position;
    wherein in the recording pulse correction step, a number of elements of the recording pulse position to be corrected is differentiated depending on the recording density that was identified in the identification step. The corresponding apparatus is also provided.

    摘要： A write strategy calibration system for an optical media playback device comprises memory for storing a write strategy table. A control module generates a write signal to write a training pattern to an optical storage medium according to calibration data stored In the write strategy table. A write strategy analysis module receives a read signal indicative of the training pattern written to the optical storage medium and adjusts the calibration data according to the read signal.

    摘要： An optical disc drive, which is capable of stably controlling a laser diode without having an influence on other data by recording a test pattern in at least one of a run-in area and a run-out area of a recording unit block and detecting the characteristics of the laser diode, and a method of controlling the same. The method of controlling an optical disc drive can include recording a test pattern in at least one of a header and a tail of a recording unit block including a data area having a predetermined size, detecting input/output characteristics of a laser diode via the recorded test pattern, and controlling the laser diode such that the laser diode generates a target output on the basis of the detected input/output characteristics.
