Recording apparatus using semiconductor laser |
摘要 |
A recording apparatus using a semiconductor laser comprises a video signal processor which reduces the time for conduction of current in a semiconductor laser diode by cutting away a pulse signal for turn on/off of the semiconductor laser diode at its leading and trailing edges. For both a one pulse signal representative of an isolated one dot and a one pulse signal representative of continuous plural dots, the signals being transmitted from a host, the processor contracts the pulse width of the pulse signal at its leading and trailing edges to permit uniform recording which is not influenced by the manner of arranging dots.
