    摘要: An optical disc molding apparatus is able to mold an optical disc in which the occurrence of swollen portions of trumpet shape on the upper and lower surfaces of on the outer peripheral portion of a disc base may be minimized and in which a burr may be prevented from being produced on the outer peripheral portion of the disc base. In the optical disc molding apparatus having a ring (6) for molding an outer diameter portion of a disc base and holding a stamper (5) for transfer a signal pit, a holding surface of the ring (6) for holding the stamper (5) is formed as the concave and convex surfaces comprising a plurality of concentric land portions (21) and a plurality of concentric groove portions (22). The outer peripheral surface of the stamper (5) is held by each land portion (21) with a pressure.

    摘要: Data processing method and apparatus for converting data such as character data or image data of a resolution X into data of a resolution Y which are effective for use in, particularly, a recording apparatus such as an ink jet printer or the like. The data processing method comprises a first dividing step of dividing the data of the resolution X in the main-scan direction every A bits; a first converting step of converting the divided A-bit data into the B-bit data of the bit number B by using a first conversion pattern table; a second dividing step of dividing the data which was obtained by repeating the conversion by the first converting step by a number of times as many as a plurality of lines in the sub-scan direction every A bits; a second converting step of converting the divided A-bit data into the B-bit data of the bit number B by using a second conversion pattern table; and a reducing step of reducing the data of the resolution Y obtained by the second converting step by a thinning process by using a third conversion pattern table.
