    摘要： A gap pull-in method and an optical disc apparatus. Whether light condensed on a disc as an actuator ascends is near-field light is determined using a gap error signal. The range of an actuator driving voltage value during a section where the decrease rate of the gap error signal is constant is obtained when it is determined that the light condensed on the disc is near-field light. Gap pull-in is performed on the disc during a section where the actuator driving voltage value is within the obtained range.

    摘要： An apparatus and method for generating a tracking error signal (TES). A low level TES is prevented from being generated due to noise in an optical disk drive for reproducing a high-density multi-layered optical disk. The apparatus includes: an N-split optical reception element to receive light reflected by a disk loaded in the optical disk drive, a phase difference signal detection module to detect a plurality of phase difference signals using signals output from the N-split optical reception element, a pulse width modulation module to modulate pulse widths of the plurality of phase difference signals so that the pulse widths of the plurality of phase difference signals are magnified, and a difference detector to detect a difference between the plurality of phase difference signals whose pulse widths are modulated and outputting the detected difference as the TES. N may be a positive integer.

    摘要： A method of improving a defect countermeasure of an apparatus for reproducing an optical information storage medium. The method includes generating a defect detection signal corresponding to a defect duration from an RF signal input from an optical pickup, outputting a servo hold signal by performing an AND operation of the defect detection signal and a predetermined pulse width modulation signal, and if reproduction fails in a servo hold on state, switching the servo hold on state to a servo hold off state, outputting the servo hold signal again by reflecting a time delay on a pulse width of the servo hold signal when entering into the defect duration again, and adding track and focus offsets to a held servo value of the time delayed servo hold on duration. Accordingly, a countermeasure of a case where normal data reading fails due to a defect can be improved.
