    摘要: In a recording method for a rewritable optical recording medium, immediately before a prospective leading pulse that is a time section where recording light of write power Pw irradiates a phase-change recording layer for the first time as a front low-power energy irradiating step, light of bias power Pb irradiates the phase-change recording layer for a first set time length yT as a preceding low-power energy irradiation step. And immediately after the leading pulse, the light of bias power Pb irradiates the phase-change recording layer for a set time length xT as a succeeding low-power energy irradiation step. The relation between x and y satisfies: 0.95≦x+0.7*y≦2.5. The high-power energy beam irradiates the recording medium in such a manner that a period of irradiation for pulses subsequent to the leading pulse is in a range of from 0.5T to 2.5T. The result is that it is possible to facilitate forming/erasing amorphous marks even in a phase-change recording medium devoid of a reflective layer, without any risk of narrowing the range of effective crystallization speeds.

    摘要: An optical disc having excellent recording/retrieving characteristics and capable of improving the surface properties of the reflective layer without reducing the thermal conductivity, the reflectivity and producibility. An optical recording medium for recording and/or retrieving information by irradiation of light, which comprises a substrate, and an interlayer, a reflective layer containing a metal as the main component and a recording layer, formed in this order on the substrate directly or via another layer made of a resin or a dielectric material, wherein as observed from a light-incoming direction, the reflective layer is located in front of the interlayer, the interlayer contains the same metal as the metal constituting the main component of the reflective layer and also contains oxygen and/or nitrogen, and the interlayer has a content of the metal smaller than the reflective layer.

    摘要: A retractable ballpoint pen is free from leakage of ink from its tip and ink back-flow attributable to shocks produced by retractable operation, and is capable of satisfactory writing performance. The retractable ballpoint pen has a ballpoint pen refill (3) having a ballpoint pen tip (7) disposed in a forward end of an ink-accommodating tube (8), a ball (9) held for free rotation in a forward end part of the ballpoint pen tip (7). The retractable ballpoint pen is provided with a retracting mechanism (5, 6) for projecting a forward end of the ballpoint pen tip (7) and retracting the same through an open forward end (2a) of a barrel (2). A water-based ink (15) contained in the ink-accommodating tube (8) contains a thixotropic agent and has a viscosity at a rate of shear of 1.9 sec−1 at 20° C. in the range of 900 to 2500 mPa·s. A restricting passage (20) is formed in a passage for the water-based ink (15) contained in the ink-accommodating tube (8) to flow to the ball (9) and has a cross-sectional area measured perpendicular to the axis of the ink-accommodating tube (8) in the range of 0.4 to 0.8 mm2. The restricting passage (20) limits the flow of the water-based ink (15).
