Reproduction is made on the signal recorded so as to obtain a “β” value indicative of asymmetry of the reproduction signal to each the recording power. In this instance, the “β” value, or the optimal recording power Pwo is determined, with utilizing an area or region, being called APC region, which is provided in a part of the recording regions, which are divided into a large number thereof, each being made of a predetermined information recording unit (RUB), being unique to that disk, and further equalization thereof.

摘要： According to the present invention, an optimum value of a laser power for recording data on a high-density optical disk can be set with high accuracy. A test signal whose erase power Pe is fixed and recording power Pw is varied is recorded on the optical disk. The recorded signal is reproduced and a β value representing asymmetry of the reproduced signal is obtained for each recording power. An optimum recording power Pwo is set from a recording power with which the obtained β value becomes a target β value. Hereby, the fixed erase power Pe is determined from measurement results of a value of a modulation factor M of another test signal recorded. Alternatively, the fixed erase power Pe follows strategy information defined in advance for the optical disk. Or Pe≈0 is used regardless of the optical disk.

摘要： A coated cemented carbide member includes a cemented carbide base material containing a binder metal of at least one iron family metal and a hard phase, and a coating layer provided on the surface of the cemented carbide base material. The hard phase contains at least one metal component selected from carbides, nitrides, carbo-nitrides and carbonic nitrides of Zr and/or Hf and WC. A layer consisting of only WC and an iron family metal or a binder phase enriched layer or a low hardness layer is provided on an outermost surface of each insert edge portion of the cemented carbide base material. The coating layer is a single or multiple layer consisting of at least one metal component selected from carbides, nitrides, carbo-nitrides, oxides and borides of metals belonging to the groups IVB, VB and VIB of the periodic table. Due to this structure, it is possible to improve chipping resistance with no deterioration of wear resistance in the coated cemented carbide member to be used, for example, as a cutting tool.
