A template 1 is brought close to or in contact with a surface to be patterned 111 and patterns are formed with liquid 62 on the surface 111. This method comprises the steps of: bringing the template 1 close to or essentially in contact with the surface 111, supplying liquid 62 to a plurality of through holes 12 established in the pattern transfer region 10 of the template 1 for supplying the liquid 62, and separating the template 1 from the surface 111 after the liquid 62 is adhered to the surface 111 via the through holes 12.
摘要:
The present invention relates to a magneto-optical media. Especially, the present invention relates to the device for assuring a high S/N ratio by controlling optical phase difference owned by the media by optimising the film structure of a multi-layered thin film. The structure of the multi-layered thin film is such that at least the first protective film of the thickness between 400 Å and 700 Å, a recording film of the thickness between 150 Å and 300 Å, the second protective film of the thickness between 150 Å and 250 Å, and a reflecting film of the thickness between 400 Å and 800 Å, are successively laminated. The first protective layer and the second protective layer are both suitably made of AlSiN, SiN, or SiO 2 having refractivity between 1.95 and 2.05. It is suitable that the recording layer has the composition
Nd x Dy y (Fe z Co) 100-x-y ,
or
Nd x (DyTb) y (Fe z CO 1-z ) 100-x-y ,
where the following relation holds : 25 at % ≦ x + y ≦ 30 at %, 0 at % ≦ x ≦ 8 at %, and 0.07 ≦ z ≦ 0.43 at %.

A magneto-optical recording and reproducing apparatus comprises coding and modulating means (11) for (1,7) RLL encoding and then NRZI encoding a digital information series {A i }; a magneto-optical drive (3) for recording said encoded series {a i } to a magneto-optical recording medium, and reproducing an analog signal from said medium as elementary waveform sequence e(t) using an optical head; a transversal filter type waveform equalizer (14) for waveform equalizing elementary waveform sequence e(t) by applying the transfer function (1 + 2D + 2d 2 + D 3 ) of the PR(1,2,2,1) encoding method to the elementary waveform sequence where delay operators D have a delay time of the encoded sequence cell width T b ; a low pass filter (15); an A/D converter (16) for sampling and quantizing the equalized waveform sequence x(t); and a Viterbi decoder (17) for comparing the e A/D converter output {a i } with a particular expected value, and determining the most probable path as decoding sequence {A i }. The transfer function of PR(1,2,2,1) encoding well approximates the combined transfer function of the magneto-optical drive (3) and the waveform equalizer (14), achieves strong suppression of interwaveform interference, and achieves high density recording. The Viterbi decoding means has a long minimum free distance, and an improved error correction rate.

摘要:
A liquid crystal display device has a light source and includes a two-dimensional light-emitting element array plate formed of a plurality of light-emitting elements arranged in a plane array, and a liquid crystal panel having a plurality of pixels. Each of the pixels corresponds to each of the light-emitting elements. A light-projecting portion of each of the light-emitting elements is disposed within a light-transmitting region of the corresponding pixel.
