    摘要： An object of the present invention is to provide a material having spectroscopic properties, light resistance, solubility and thermal decomposition properties suitable for recording for DVD-R. More specifically, the present invention provides squarylium compounds in a state of a metal complex represented by the general formula (I): wherein, R1 and R2 are the same or different, and represent an alkyl group optionally having a substituent, an aralkyl group optionally;,having a substituent, an aryl group optionally having a substituent, or a heterocyclic group optionally having a substituent; Q represents a metal atom with a coordination ability; q represents 2 or 3; and A represents an aryl group optionally having a substituent, a heterocyclic group optionally having a substituent, or Y═CH— wherein Y represents an aryl group optionally having a substituent or a heterocyclic group optionally having a substituent.

    摘要： A recording and reproducing method, wherein, on recording and reproduction of a recordable DVD medium, which has a recording layer containing an organic dye on a substrate having a guide groove with wobble, wherein linear velocity conditions for CLV recording is recorded on the substrate, recording starts at a linear velocity less than a highest linear velocity at the innermost circumference; when the linear velocity is switched over to the highest linear velocity on the way, a comparison is made between an optimum recording power of Po at the highest recording velocity that is temporarily optimized by test-writing in a power measurement area at the outermost circumference and an optimum recording power of Pi at the highest linear velocity that is recorded in the substrate; in the case of Po>Pi, a value given by the formula of “(Po+Pi)/2+(Po−Pi)2Pi” is employed as a recording power with which recording starts at the highest linear velocity; and in the case of Po≦Pi, Pi is employed.
