Various layer separation states are generated by the combination of a polyamide acid ester and a polyamide acid and a long residual image characteristic cannot be further improved merely by combining them. A liquid crystal display device comprises a substrate, a liquid crystal layer, and an orientation film placed between the substrate and the liquid crystal layer. The orientation film comprises a polyimide precursor having two or more components. In the polyimide precursor, an octanol-water partition coefficient is defined as log P and the difference in log P (&#x394; log P) between the two components having most distant log Ps is set so as to fall within a prescribed range.

A liquid film applicator means can apply a photosensitive lyophobic filmto a substrate. An exposure unitis placed on the back side of the substrate and forms the lyophobic film applied on the substrate into a pattern in alignment with gate electrodes. A dropping unitdrops a test liquid to a surface of the substrate having a pattern of the lyophobic film formed by the exposure means. A measuring meansdetects the droplet dropped by the dropping unit. A determining means determines whether the pattern of the lyophobic film formed by the exposure means is proper or not based on the droplet detected by the detecting means.

A lubricating film is provided for a magnetic disk having a data region and a CSS region formed on its surface. The lubricating film ensures low stiction and good resistance to contact sliding in the data region and also ensures good CSS durability in the CSS region. Therefore, it is possible to provide a magnetic disk and a magnetic recording/reproducing device which do not cause problems with sliding between the magnetic head and the magnetic disk while the apparatus is running normally and even when the apparatus stops accidentally. The lubricating film formed in the data region of the magnetic disk is firmly fixed to the surface of the magnetic disk and is hardly liable to stiction. In addition, it is thick enough to ensure good durability even in the case of contact sliding. The lubricating film formed in the CSS region is composed of a lubricant which is firmly fixed to the surface of the magnetic disk and another lubricant which is weakly fixed to the surface of the magnetic disk; therefore, it is superior in CSS durability. This contributes to the highly reliable magnetic disk and magnetic recording/reproducing device.

A magnetic recording medium comprising a non-magnetic substrate and a magnetic layer and a protective layer which are formed on the non-magnetic substrate in that order, wherein a substance(s) as a single component or a plurality of components, which constitute a liquid continuously supplied to the surface of said protective layer, are adsorbed on or react with the surface of said protective layer to form a lubricating film having low frictional properties and low wearing-out properties. The present invention can realize negligible friction and wear resistance even in severe sliding at a very slightly kept-off or completely contacted state by continuous supply of a liquid lubricant prepared by adding a fluoro compound and an extreme pressure agent or an oiliness agent to a solvent to the surface of a disc, and can provide a magnetic recording reproducer having excellent sliding-resistant characteristics.

Magnetic recording medium and magnetic recording reproducer

A magnetic storage apparatus includes a substantially non-flexible magnetic recording medium, a magnetic head slider having a reading/writing element mounted therein and liquid lubricant provided on the surface of the magnetic recording medium. The liquid lubricant is a liquid in a Newtonian range having a viscosity which is substantially constant irrespective of a shear rate or a liquid having the property that the actual viscosity is increased with increase of the shear rate. The magnetic head slider maintains a gap between the slider and the magnetic recording medium to perform reading and writing while being moved on the liquid lubricant intermittently or continuously in a contact manner with the liquid lubricant. There is provided a device for maintaining a constant flying height even if a movement speed is varied, which flying height is represented by the size of the gap. Thus, the magnetic storage apparatus of the liquid bearing system or the contact system has only very small forces such as liquid drag force and friction force or sticking force and is capable of performing stable slider movement, performing high-speed seeking operation with high reliability and performing high-density recording.

Magnetic disk apparatus employing liquid bearing type or physical

The present invention is aimed at providing a magnetic disk and a magnetic disk apparatus both of which have a high performance lubricating film which makes continuous sliding endurance and low adhesiveness compatible, and a lubricating film having a self repairing function which makes it possible to recombine scratched off lubricating agent from the magnetic disk surface by sliding with a head onto the magnetic disk surface. The lubricating film comprises at least two kinds of lubricating agents each of which forms an individual layer, the layers being laminated. An adhesion enhancing layer is formed between a magnetic film and a lubricating agent at the surface of the magnetic disk, and the adhesion enhancing layer is fixed onto the magnetic film surface. Then, the adhesion enhancing layer and the lubricating agent are combined. The adhesion enhancing layer and the lubricating agent form a salt or complex body, and the lubricating agent can repeat adsorption and desorption with the adhesion enhancing layer reversely by a thermal reaction.

In an optical recording method which utilizes hole burning, a plurality of sorts of light absorption centers having different properties are caused to coexist or to exist in the form of layers, thereby to remove the problem that, although the multiplicity of recording is high, the spacial recording density is low, so the overall recording density is low. Accordingly, the present invention can provide an optical recording method of very high recording density.

Optical recording method

A method for producing a polarizer patterned with a plural number of portions having a polarizing ability or direction of polarization comprising the first step of producing a surface oriented in a pre-determined direction on a substrate, the second step of producing a polymerizable molecular layer which comprises polymerizable molecules on the above surface, the third step of polymerizing the molecules in said polymerizable molecular layer into a desired pattern and the fourth step of removing the unpolymerized portion of said polymerizable molecular layer. For example, the following procedure is repeated on one surface of a substrate to be given a polarizing ability: (1) An organic thin film uniformly oriented in a particular direction is produced by the Langmuir-Blodgett method, (2) a polymerizable molecular layer is produced on the above thin film, (3) the molecules in the polymerizable molecular layer is polymerized into a desired pattern and (4) the portion left unpolymerized of the polymerizable molecular layer is removed. By this treatment, a polarizer having as many orientation directions as the number of repetitions is obtained. The orientational order can also be given by rubbing in place of the Langmuir-Blodgett method.
