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.

摘要： A focus pull-in method to perform an accurate focus pull-in operation in an optical disc drive using a holographic optical element (HOE) in consideration of a pseudo s-curve and an optical disc drive capable of performing the focus pull-in method, the method comprising checking whether a pseudo s-curve is contained in a focus error signal that is generated when an object lens of the optical disc drive is moved upwards or downwards, and, if the pseudo s-curve is contained in the focus error signal, controlling a focus pull-in operation for a disc loaded into the optical disc drive according to detection conditions for the pseudo s-curve. Accordingly, it is possible to accurately focus the data layer even during the driving of the disc that uses a wavelength that results in a low diffractive efficiency of the HOE.
