Abstract: An apparatus and a method for writing and reproducing data of an optical disk are provided to prevent an error resulting from initial focus dependency when seeking a recording method and to confirm that the recording method learning is stable by adjusting the focus bias to a section of a maximum value of an RF(Radio Frequency) signal or of a minimum value of a jitter. An apparatus for reproducing information record comprises an optical disk(10), an optical pickup(20), and an optical driver(30). The optical pickup has a laser diode(21) and a laser driving part(22). A detection part(23) detects the laser irradiated on a data recorded surface of the optical disk, and the laser is amplified by an amplifier(24). The optical driver includes an RF(Radio Frequency) signal processing part(31), a PLL(Phase Locked Loop) part(32), a matrix jitter measuring part(33), a CPU(Central Processing Unit,34), and a recording pulse generating part(36). The RF signal processing part processes a reproducing signal reflected from the optical pickup, generates the RF signal, and converts the RF signal into a binary signal. The PLL part keeps frequency of the output signal from the RF signal processing part constant. The matrix jitter measuring part measures a jitter from the PLL error signal obtained by the PLL. The CPU adjusts focus bias to a section of a maximum value of the RF signal or of a minimum value of the jitter, or adjusts the focus bias to the center value of the laser power margin. A digital signal processing part(35) converts the RF signal into a digital signal, and demodulates or modulates the data at the time of recording.

Abstract: A method for performing OPC(Optimum Power Calibration) of an optical disc device is provided to set an OPC area by using a random value and thus to decrease processing time and perform the OPC effectively. A method for performing OPC of an optical disc device includes a step of extracting a random value by a pre-set method, and a step of selecting a test area to perform OPC, on the basis of the extracted random value(S500,S530). The extracted random value is larger than the size of the whole test area formed at the optical disc. When extracting the random value, the pre-set method is a method extracting the random value by using a random number generator. When setting the test area for the OPC, a starting point of the test area is set by using a value which is computed by calculating the random value by a regular numerical formula.
