More Information
Summary:A heat mode recordable, optical recording medium comprising: a transparent substrate; a recording layer containing a dye; and a reflective layer, wherein the recording layer comprises an organic dye, and the medium has an optimum recording power of at least 25 mW when recorded at a linear velocity v (m/sec) with a laser beam having a wavelength of 600 to 700 nm, the optimum recording power being defined as a recording power (Po) at which a jitter in recording 8/16 modulation signals is lowest and being represented by equation: Po = P1x( nu /3.5) SIMILAR 1.5P1 x ( nu /3.5) in which P1 is an optimum recording power in recording at a linear velocity of 3.5 (m/sec).
