    摘要: A method for determining a parameter space for finding optimal operating parameters for reading or writing storage medium is provided. In an embodiment of the invention, the method includes: setting a first parameter range of a first operating parameter and a second parameter range of a second operating parameter; normalizing the first and the second parameter ranges respectively and forming an initial parameter space based on the normalized first and second parameter ranges; and rotating the initial parameter space by a rotation angle and forming an actual parameter space based on the rotated initial parameter space. The actual parameter space is expected to result in more reliable optimal operating parameters.

    摘要: A method for determining optimal operating parameters for reading or writing a storage medium, with the consideration of failed experiment. In an embodiment of the invention, if one of a set of experiments, executed within pre-defined ranges with respect to two parameters, leads to an invalid characteristic measurement value, and the corresponding values of the two parameters occur substantially at ends of the respective ranges, at least one search operation is determined according to the failed experiment(s) and a new set of experiments is generated according to the previous set of experiments and the search operation to avoid the failed experiment(s). The new set of experiments can result in more reliable optimal operating parameters.

    摘要: An optical recording apparatus includes an optical pickup unit for generating and directing optical signals onto a given optical medium, and for detecting corresponding reflected optical signals from the optical medium; a focus motor for moving a focusing lens on the optical pickup according to a focus signal for adjusting a defocus of the optical signals on the optical medium; and a focus controller for generating the focus signal. During write operations of the optical recording apparatus, the focus controller is for performing write defocus calibration on the given optical medium to determine an optimal write defocus value for the optical medium. If the optical medium has multiple layers, the write defocus calibration is performed on a particular layer of the optical disc toward which write operations are directed. If the optimal defocus write value is different than a starting write defocus value, an updated write defocus value is stored.
