摘要： A plasma processing apparatus and a method therefor which can achieve a preferred process rate, a fine pattern process capability, a selectivity and uniformity of processing at the same time compatibly for a large size wafer, which effects are achieved by controlling the plasma state and the dissociation state of etching gas through control of the electron resonance through application of a magnetic field thereto. A high frequency power at 20-300 MHz is applied across a pair of electrodes in a vacuum process chamber, and a magnetic field is formed parallel to the plane of the electrodes in the space between the electrodes. By controlling the intensity of the magnetic field in a range of 100 gauss or smaller, formation of electron cyclotron resonance and electron sheath resonance occurring from interaction between the electrical field and the magnetic field in the electrode sheath portion is controlled. Thereby, the plasma state, i.e., the electron density, electron energy distribution and dissociation state of the process gas in the plasma, can be controlled. The magnetic field is generated by a plurality of coils, an outer shield, and pendant yoke to form magnetic field parallel to the plane of the electrodes in the space between the upper and the bottom electrodes.

摘要： An optical disc drive according to the present invention can write data on both a write-once disc and a rewritable disc. The drive includes: a disc recognizing section 110 for recognizing the type of a given optical disc as a write-once disc or a rewritable disc; and track skipping detection signal generating section, which outputs track skipping detection signal when a first condition on tracking error is satisfied if the given optical disc, on which data is being written, has turned out to be a write-once disc. On the other hand, if the given optical disc has turned out to be a rewritable disc, the track skipping detection signal generating section outputs track skipping detection signal when a second condition on tracking error, which is different from the first condition, is satisfied. A control section stops writing the data in response to the track skipping detection signal while the data is being written.

摘要： An optical disc apparatus includes: a defect detecting section 124 for detecting, based on a light detection signal and with respect to a preset detection reference level, a fingerprint or a bubble on the disc 102 as a defect to output a defect detection signal; and a waveform shaping section 126 to output a hold signal that holds, in response to the defect detection signal, a signal from a tracking control section 109 at a level just before the defect has occurred. The apparatus is initially operated not to hold the signal from the tracking control section 109 even if there is a defect. But once a tracking failure has occurred during a read operation, settings are changed to hold the signal from the tracking control section 109 against the defect while the read operation is retried.

摘要： This optical disc drive can read and/or write data from/on an optical disc 20 with multiple information layers including first and second information layers. The drive includes: a light source 3, 4 that emits the light beam; an objective lens 1; an actuator 2 for moving the objective lens perpendicularly to the information layers; a focus error generator 7 for generating a focus error signal representing how much the light beam has been converged on a target one of the information layers; and focus control means for forming a focal point of the light beam on the target information layer by driving the actuator in accordance with the focus error signal. According to the present invention, while a focus jump is being made to shift the focal point of the light beam from the first information layer of the optical disc 20 to the second information layer thereof by moving the objective lens 1, wavelengths and/or numerical apertures for the light beam are changeable while the objective lens 1 is moving.
