摘要： Using MSR (magnetically induced super-resolution) technology, a read-head field is applied to a magneto-optical recording medium when reading an information signal from a recording layer of a magneto-optical recording medium, in order to magnetize the read light-irradiated magnetic layer in one direction in a part of an area within the read light spot. The magneto-optical recording medium using MSR technology adopts the on-land recording method in which an information signal is written to the land, which enables read of an information signal by the MSR technology with a smaller read-head field.

摘要： A magneto-optical disk having recording tracks are formed along concentric grooves or a spiral groove. A non-groove region where no grooves are made is provided in a middle part of each recording track. In the non-groove region, there is formed a pit pattern representing information about the recording track. A track-counting U-groove is formed in the non-groove region, for detecting that the light spot of a reading laser beam has moved across the recording track. With the disk thus structured, it is possible to record information at high density and to access a desired recording track at high speed.

摘要： To provide a large sputtering target excellent in discharge characteristics during sputtering and in characteristics of a thin film thereby obtainable. Further, a process for producing a sintered body is provided, whereby a large green body excellent in shape accuracy can be obtained by means of cold isostatic pressing directly without preforming, and a sintered body capable of providing the above-mentioned excellent sputtering target, can be produced efficiently at a low cost.The sputtering target is produced by using a sintered body having the content of carbon contained as an impurity reduced to less than 0.005 wt %. Such a sintered body is obtainable by molding a raw material powder by cold isostatic pressing directly without adding a binder containing an organic substance or a molding aid, followed by firing. Further, it becomes possible to produce such a sintered body by using a molding die having such a construction that at the time of pressure compression, pressing is applied to a filled raw material powder only in a substantially uniaxial direction, and at the time of reducing the pressure after the completion of pressing, the pressure can be released substantially isotropically with respect to the green body. Further, a large target having the thickness of an erosion region made thick, can be easily produced in good yield, and efficiency in the use of the target can be improved.
