摘要:
A magnetic disk is produced with improved yield by forming a DLC protective film by a d.c. magnetron sputtering process conducted in a sputtering atmosphere containing oxygen. The magnetic disk carries a lubricating film on the DLC film wherein a fluorocarbon resin constituting the lubricating film contains photocrosslinking groups. A lubricating film having non-polar end groups is also disclosed.

A magnetic recording medium and head slider that can furnish excellent head flying stability, a magnetic recording device having excellent head flying stability, and a method for manufacturing, in a short time, a magnetic recording medium and head slider that can furnish such excellent head flying stability, are provided. For both of the magnetic recording medium and head slider, the protective layers are each composed of two layers, that is, a lower layer and an upper layer thereon; the ionization potential of the lower layer is made to be smaller than that of the upper layer; and the surface free energy of the upper layer is made to be 45 mN/m or less.

An object of the present invention is to provide an image correcting apparatus capable of performing zoom processing or mask processing on an image output from an imaging device, such as an image display device or an image monitoring/recording device, or on a reproduced image from an image recorder, in such a way as to adjust the exposure or luminance of the zoomed portion or the unmasked portion of the image to an optimum level and thereby allow display of a clear image.An image correcting apparatus of the present invention comprises: image input/output interfaces; zoom processing means for zooming an area of an input image; luminance histogram processing means for creating a luminance histogram of the zoomed area or an unmasked area of the image; and exposure correction processing means for adjusting the exposure or luminance of the zoomed area or the unmasked area to an appropriate level based on the luminance histogram created by the luminance histogram processing means.

A lubricant is provided that can form a sufficiently thin one-molecule film surface even when it is highly polymerized. When used for a magnetic recording medium lubricant layer and/or a head slider lubricant layer of a magnetic recording device, it can make the film thickness of the lubricant layers very small, with the result that it can furnish an increased reliability to the magnetic recording device in a wide temperature-range environment without damaging the flying stability. This lubricant comprises a fluorine-containing polymer having a specific structure. Such a fluorine-containing polymer can be manufactured by reacting a compound having a specific structure and 1,3-butadiene diepoxide.

A lubricant is provided that achieves a sufficiently small one-molecule-layer film thickness even when it has a high molecular weight, and has an increased reliability in a wide temperature range environment without losing the flying stability, by making the film thickness of a lubricant layer very small when it is used for the magnetic recording medium lubricant layer and/or head slider lubricant layer of a magnetic recording device. This lubricant comprises a fluorine-containing polymer, the lubricant having a relationship: Y

A head slider to which little amount of contaminants is adhered, that can form a uniform and flat head lubricant layer surface and that has excellent ultra-low floating properties, as well as a magnetic recording device equipped with the head slider are provided. The head slider is equipped with a head slider lubricant layer having an average film thickness of not more than 2.5 nm, and composed of a water-repellent resin, the lubricant layer being formed on the head slider surface and head slider protection layer surface facing the magnetic recording medium, and the surface tension of the head slider lubricant layer determined by the Fowkes equation is not more than those of the head slider surface and head slider protection layer surface.
摘要:
An exposure apparatus performs exposure for a substrate by filling a space between a projection optical system and the substrate with a liquid and projecting an image of a pattern onto the substrate through the liquid by using the projection optical system. The exposure apparatus includes a substrate stage for holding the substrate, a liquid supply unit for supplying the liquid to a side of an image plane of the projection optical system, and a focus/leveling-detecting system for detecting surface information about a surface of the substrate not through the liquid. The exposure apparatus performs liquid immersion exposure for the substrate while adjusting a positional relationship between the surface of the substrate and the image plane formed through the projection optical system and the liquid, on the basis of the surface information detected by the focus/leveling-detecting system. The liquid immersion exposure can be performed at a satisfactory pattern transfer accuracy.
摘要:
An exposure apparatus having a plurality of projection optical systems where each of the projection optical systems projects a predetermined pattern onto a substrate and forms an exposure field on the substrate. The exposure apparatus also includes a substrate stage which holds the substrate and which moves in at least a scanning direction extending in a straight line. The plurality of exposure fields are arranged along a direction crossing the scanning direction, and the projection optical systems and the substrate relatively move during a pattern projecting operation along the scanning direction.
摘要:
An exposure method includes first through third steps. In the first step, respective first and second illumination regions of a mask having a predetermined pattern are illuminated with an illumination light having a predetermined wavelength. In the second step, an image of the mask is formed, respectively, in first and second exposure regions (formed on a substrate) based on the illumination that passes through the first and second illumination regions. The first and second exposure regions each have a substantially polygonal shape defined by two parallel sides and two sides other than the two parallel sides. In the third step, the first and second exposure regions and the substrate are moved relatively in a first direction such that the first and second exposure regions are formed in different positions in a second direction which crosses the first direction.
