摘要： A focus control apparatus for a multilayer optical recording medium performs an adequate focus jump on a multilayer optical recording medium. Threshold values are set according to the amount of a level change in a focus error signal of a loaded multilayer optical recording medium, and focus jump control is conducted based on the result of comparison between the level of the focus error signal and the set threshold values. Positive and negative threshold values to be compared with the level of the focus error signal to detect a zero-crossing point of the focus error signal are set in accordance with the amount of a level change in the focus error signal, after which an acceleration operation of the focus actuator is started in response to a focus jump instruction to shift the focus position of read light for a focus jump, the acceleration operation is stopped in accordance with zero-crossing detection, a deceleration operation of the focus actuator is started thereafter and is stopped in accordance with zero-crossing detection, so that the operation returns to the focus servo operation.

摘要： A tilt servo apparatus which can correct a tilt error at a high speed and with high precision irrespective of a magnitude of the tilt error even if a response speed of a liquid crystal device decreases is provided. An amount of change and an increase/decrease of a signal intensity are detected by changing a correction value of a tilt error correcting arrangement by a first correction width, and a correction width of the correction value and a correcting direction are determined on the basis of the detection result. When the amount of change of the signal intensity is smaller than a predetermined amount of change, the correction width is changed to a second correction width which is smaller than a first correction width. When it is larger than the predetermined amount of change, the correction width is changed to a third correction width larger than the first correction width. The correction width is also determined in accordance with a change in environmental temperature.

The secondary side control circuit includes a peak period detection circuit and a determination reference voltage generation circuit. The peak period detection circuit detects a peak period of the drain voltage. The determination reference voltage generation circuit generates a reference voltage to be used as a reference for determining the peak period based on a voltage in the peak period. The peak period detection circuit detects the peak period based on the drain voltage and on the reference voltage.

摘要： A method for fixation, onto a layer comprising an amorphous carbon film and provided on a base material, of a layer comprising a material condensation-reacting with hydroxyl groups on a surface of the amorphous carbon film, whereby, in the layer comprising an amorphous carbon film and provided on the base material, the amorphous carbon film can have a holding power which is strong enough to fix the layer comprising a material condensation-reacting with a hydroxyl group on the surface of the amorphous carbon film and can have uniformity of the holding power. Si and O are added into the layer comprising an amorphous carbon film to thereby improve adhesion durability and binding uniformity of the layer comprising a material condensation-reacting with a hydroxyl group. Particularly, by using a fluorine-based silane coupling agent, it is possible to impart high functions such as water repellency/oil repellency, abrasion resistance, chemical resistance, low friction properties and non-tackiness to the amorphous carbon film.
