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： In fabricating process using a light beam or electron beam, reactivity is determined by the total amounts of photons or electrons absorbed by resist and consequently, fine fabrication cannot be achieved. On the other hand, thermal recording has been proposed but in the thermal recording, miniaturization of the fabrication size depends on a spot size of light beam or electron beam used for recording and is limited. Under the circumstance, to ensure a fine uneven pattern to be produced with high reproducibility, only crystal of a recording film used in a phase-change optical disk is peeled off by using an alkaline solution or pure water to leave only an amorphous portion on the sample surface and as a result, crystalline and amorphous patterns are converted into an uneven pattern.
摘要翻译：在使用光束或电子束的制造工艺中，反应性由抗蚀剂吸收的光子或电子的总量确定，因此不能实现精细的制造。另一方面，已经提出了热记录，但是在热记录中，制造尺寸的小型化取决于用于记录的光束或电子束的光点大小，并且是有限的。在这种情况下，为了确保以高再现性产生精细的不均匀图案，只有使用碱性溶液或纯水才能将相变光盘中使用的记录膜的晶体剥离，才能在样品表面，结果，晶体和非晶形式转变成不均匀的图案。

摘要： An optical disc using super-resolution effects that achieves higher-density recording exceeding the optical resolution suffers from the signal-quality degradation caused by the normal resolution component included in the reproduction signal. To address this problem, a data reproduction method is provided. In the method, characteristic error patterns are identified and parity check codes in conformity with run-length limited coding are used to carry out efficient and reliable error correction. Error patterns caused by the normal resolution crosstalk are localized in the leading edges of a mark following a long space and in the trailing edges of a long mark. Whether an error exists in the data is determined by use of the parity check codes. When an error occurs, a pattern in which an error is most likely to occur is selected from the above-mentioned patterns by taking account of the edge shift direction, and then the error therein is corrected.

摘要： Disclosed are an information reproduction method and an information recording medium that allow reproducing information below a diffraction limit. A recording layer formed with recording marks consisting of a nucleation inducer and a reading layer are provided. When a reading beam is irradiated, a predetermined area of the reading layer is crystallized based on the recording mark of the recording layer such that the area is magnified to a size larger than the recording mark, and information is thus reproduced. Information of the recording marks below the diffraction limit can be reproduced without using a special information reproduction apparatus.
