| 英文摘要 | In an information recording method which uses short-pulse light using relaxation oscillation of semiconductor laser, the direct overwrite characteristics can be improved by use of light having a cooling pulse of duration Tc driven by a drive current lower than an emission threshold current of the semiconductor laser after a recording pulse of duration Tw at the rear end of a short pulse train which records a mark of a predetermined length, and a boost pulse of duration Tbst driven by a drive current higher than an erase pulse drive current at the head of an erase pulse. The cooling pulse Tc may be greater than 0.8T where T is the clock channel width and Tw may be less than 5 ns. |
