摘要： A super resolution optical reproducing system, which can recognize a recording mark less than a resolution limit, removes the effect of a high-frequency noise component of a high power signal obtained by irradiating a laser beam with high read power. The same recording region of an optical recording medium is irradiated according to an irradiation spot by a laser beam with an ordinary read power and an irradiation spot by a laser beam with high read power to obtain a ordinary power signal and a high power signal. The ordinary power signal and the high power signal are normalized to an average level by high pass filters and low pass filters of a high power signal processing circuit and a ordinary power signal processing circuit. Then, a subtracter subtracts the ordinary power signal from the high power signal to obtain a substrated signal. The differential signal and a ordinary reproduced signal that has passed through a parallel processing circuit are amplitude-modulated by a pre-equalizer and a parallel pre-equalizer and then added up by an adder to form a composite signal. The composite signal is output as a reproduced signal.

摘要： In preparing an optical recording disk by spin coating a dye-containing solution to an annular substrate to form a recording layer thereon, a circular channel is preformed in the substrate in proximity to the inner peripheral edge of the substrate for defining an inner boundary of the recording layer. Then the recording layer is free of corrugations near its inner boundary, leading to improved adhesion of an overlying protective film and a minimal variation in reflectivity.

摘要： An optical recording disk includes a dye base recording layer, an intermediate layer, and a reflective layer on a substrate in the described order. The reflective layer is composed of one or more metal elements, for example, copper alloy, and the intermediate layer contains a compound of the one metal element or a compound of at least one of the metal elements, for example copper oxide. The intermediate layer minimizes undesirable interactions between the recording and reflective layers.
