A mounting device includes: an application part applying paste on a substrate to form an application body; a bonding part forming a mounted body by mounting a chip component on the substrate via the application body; a first imaging part imaging the application body after application processing and before mounting processing to acquire first image information; a second imaging part imaging the mounted body after the mounting processing to acquire second image information; and a control part controlling the application part, the bonding part, and the first and second imaging parts, and obtains a 3D application body shape (first shape) from the first image information as a first shape and calculates a 3D mounted body shape (second shape) from the second image information. The control part evaluates the application processing or the mounting processing based on the first and the second shapes.

Mounting apparatus

A pick-up devicefor picking up a semiconductor chipattached to a front surface of a sheet materialis provided with: a stagethat includes a material a part or the entirety of which is capable of transmitting a destaticizing electromagnetic wave having an ionization effect and that attracts and holds a rear surface of the sheet material; a jacking-up pinfor jacking up the semiconductor chipfrom the rear side of the stage; and a destaticizing mechanismthat destaticizes charge generated between the semiconductor chipand the sheet materialby irradiating the rear surface of the semiconductor chipwith the destaticizing electromagnetic wave that is made to pass through the sheet materialfrom the rear side of the stage

Pick-up device and pick-up method

A method of recording information on and reproducing information from a magnetooptical recording medium which includes first and second magnetic layers. The method includes the step of projecting a light spot onto the medium. When reproducing information, the light spot is projected onto the medium from the side of the magnetic layer. In this method only a high temperature region of the second magnetic layer within a light spot projection portion is changed to a perpendicular magnetization film so that information recorded in the first magnetic layer is transferred to the perpendicular magnetization film of the second magnetic layer. In addition, information which is transferred to the second magnetic layer is detected by using reflected light from the medium which is subjected to the magneto-optic effect from the perpendicular magnetization film of the second magnetic layer. When recording information, a magnetic field is applied, whose magnetization direction is modulated according to information, to a light spot projection portion of the medium so the magnetization of the second magnetic layer is oriented to the direction of the applied magnetic field, and the magnetization of the second magnetic layer is transferred to the first magnetic layer to form a record bit.

Magnetooptical recording medium and information recording and

A magnetooptical recording medium includes a first magnetic layer, in which data is to be stored, and a second magnetic layer, wherein the first magnetic layer is perpendicularly magnetizable at both room temperature and a raised temperature above room temperature, and the second magnetic layer is in-plane magnetizable at room temperature and becomes perpendicularly magnetizable at the raised temperature, which is composed of Gd.sub.x (Fe.sub.100-y Co.sub.y).sub.100-x, where 27.ltoreq.x.ltoreq.31 and 28.ltoreq.y.ltoreq.50.

An optical recording medium has tracking tracks and recording tracks interposed between the tracking tracks. The width of the recording tracks in a specific region is larger than that in other region.

Optical recording medium and process for producing the same

An optical recording medium is provided with optical guide grooves and prepits representing for example address data, in a land portion sandwiched between the grooves. The reflectivity in the bottom portion of the prepits is made higher than that of the land portion. An antireflection film is provided on the medium such that, in case where the reflectivity of the antireflection film decreases with the increase in the thickness of the antireflection film, the thickness of the antireflection film on the bottom of the prepits is selected smaller than that on the land portion. In the case where reflectivity of the antireflection film increases with the increase in the thickness of the antireflection film, the thickness of the antireflection film on the bottom of the prepits is selected larger than that on the land portion.

There is disclosed an optical recording medium provided with an optical recording layer on a substrate, in which a layer of nitride of a substance selected from tungsten, zirconium, titanium, niobium, vanadium, tantalum and chromium is formed on a side or both sides of the optical recording layer.

Opto-magnetic recording medium

In an optical recording medium having an optical recording layer provided on a substrate, a carbide film of a substance selected from among tungsten, boron, molybdenum, hafnium, niobium, titanium, chromium, vanadium, tantalum and silicon is formed on one or each side of the recording layer.

Optical recording medium
