Abstract:
A drive control apparatus and method for an optical disk are provided to improve reproduction quality of the optical disk by storing a median of an amplification gain and a median of an amplification frequency in a memory, and stabilizing a PLL(Phase-Locked Loop) operation by using the medians. A drive control method for an optical disk comprises the steps of: setting an amplification frequency band of an RF waveform equalizer(S210); successively modifying an amplification gain of the RF waveform equalizer(S220); storing a median of the amplification gain of the RF waveform equalizer(S230); successively modifying the amplification frequency band of the RF waveform equalizer(S240); and storing a median of the amplification frequency band of the RF waveform equalizer(S250).

PURPOSE: A PLL device and a method of a disk driver are provided to supply a PLL which does not consider a phase error for a reproduction signal having the shortest period of a disk or a period near to the shortest period in consideration of code features of the disk, thereby realizing a high disk recording density. CONSTITUTION: A period checker(203) checks a period of a signal reproduced from a disk. A phase detector(201) detects a phase difference between the reproduction signal and a system clock signal, and outputs the detected phase difference as a phase error. A loop filter(205) outputs a voltage corresponding to the phase error. A transmission processor(204) processes whether to transmit an output of the phase detector(201) to the loop filter(205) by the signal outputted from the period checker(203).

PURPOSE: A method and a device for compensating for a data reproduction signal recorded on an optical disk are provided to compensate for data inputted to a Viterbi decoder by a binarizer which binarizes the data recorded on an optical disk into binarize data, thereby reproducing the stored data without an error.

If so, the system controls a value of the input signal, and outputs the controlled input signal(S630).

The photosensitive pattern is formed in an inverse taper shape. The photosensitive pattern of the inverse tape shape is formed by ashing the photosensitive pattern.
