    摘要： The present invention provides a method of making a mold for manufacturing a microlens having a smooth surface and an arbitrary aspherical surface, or more specifically, an aspheric microlens of dimensions such that an aperture is equal to or less than 1 mm and a thickness is equal to or more than 0.5 mm. A mask layer having plural circular apertures with different sizes formed therein for a mold for one lens is formed on a silicon substrate. Plural holes are formed for the lens in the silicon substrate by applying anisotropic dry etching to a surface to be processed, which is the surface having the mask layer formed thereon. The depths of the respective holes vary depending on the sizes of the circular apertures. Isotropic etching is performed to remove sidewalls of the plural holes with different depths formed in the silicon substrate, thereby merging the holes into one hole corresponding to the lens.

    摘要： Provided are a medium structure which allows track narrowing onto a three-dimensional pit selection type disc, and its corresponding optical disc device. Multiple data pit strings are formed between track guide grooves, and a phase-change recording film is formed only in the data pit strings. Thereby, a disc configuration is achieved. Reflectivity and a phase of each of a space portion and a mark portion are appropriately set. Thereby, normal resolution signal cancel is implemented to prevent deterioration in data crosstalk and a push-pull signal. An optical disc medium of the present invention is supported by an optical disc device having a configuration in which a signal is selected from a push-pull signal of a main beam and push-pull signals of sub-beams to read out wobble address information.

    摘要： A super-resolution material is formed in only a data pit, in a low temperature state of the super-resolution material, reflectivity of each of a pit portion and a space portion and an optical phase difference therebetween are set to be sufficiently small, in a high temperature state, and at least the optical phase difference between the pit and the space is set to be larger than the aforementioned value in an absolute value. Accordingly, by conducting irradiation with an appropriate read power by which substantially only one data track width can be heated to a high temperature state, a good push-pull signal can be obtained even with a track pitch being less than a diffraction limit. At the same time, by an optical device having functions such as a switching means with a DPP type, an offset correcting means of the push-pull signal due to lens shift, a shaping means of the push-pull signal, a learning means of read power, and the like, there is provided an optical disk device that corresponds to the optical disk medium of the present invention and achieves an increase in capacity.

    摘要： Super-resolution technology was proposed for generating marks smaller than the optical resolution in order to record data at high density on the optical disk. However, the achievable high density of the super-resolution technology was limited due to fluctuation of the region exhibiting the super-resolution effect due to the grain size or the molecular size comprising the super-resolution film. However fluctuation in the region exhibiting the super-resolution effect is reduced by utilizing recording marks possessing their own super-resolution effect and also by separating the recording marks from each other.

    摘要： An optical disk for recording/reproducing information tends to have fine irregularities on its substrate surface that cause an increase in noise, which irregularities are formed during the process of forming the recording layer, which is capable of changing physically or chemically in response to irradiation of laser light. This problem can deteriorate the recording and reproduction characteristics and bring about a defect on a life test or on the storage ability on the disk. To solve this problem, a method of manufacturing an optical disk having a pits-and-lands pattern employs an organic material which is modified by ultraviolet light irradiation. The transmission of the substrate is not more than 50% at one wavelength in a wavelength region from 300 to 375 nm. As a result of the ultraviolet ray irradiation, the surface of an optical disk substrate is smoothed so as to effect a reduction of the substrate noise and an improvement of the recording and reproduction characteristics. Moreover, adhesiveness between the substrate and another layer formed thereon is improved, so that the number of generated defects is reduced.
