    摘要: A test-write method for accurately and quickly determining recording conditions, and an apparatus suitable therefor. In a 2T-based strategy, recording pulse conditions are determined by separately test-writing an even-number length mark and an odd-number length mark, and then the relative positions of the even-number length mark and the odd-number length mark at the recording pulse start time are adjusted.

    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 normal resolution component included in a readout signal of a super resolution optical disc is canceled to improve quality of the readout signal. The normal resolution component is separated from the readout signal of the super resolution optical disc by using a normal resolution selection filter such as a low pass filter, a mark length determination circuit, and then the normal resolution component is subtracted from an original readout signal while gain and a phase are appropriately controlled. Thereby, an influence of crosstalk due to the normal resolution component is reduced.

    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.
