摘要： The present invention aims to, when recording pulse information are transmitted to a laser driver lying over a pickup through an optical disk, reduce the number of transmission paths or lines from a conventional transmission method and avoid degradation of recording performance due to transmission path characteristics upon fastening of a recording speed thereby to provide stable recording performance at high-speed recording. The invention of the present application reduces the number of transmission signals by encoding multi-level laser pulse information transmitted by the laser driver. Further, gray codes are used for encoding to reduce constraints of skew between bits. Furthermore, encoding is executed using each state transition and the state transitions are switched according to each recording mark and space, thereby reducing the occurrence of a short pulse on each transmission path. In addition, the presence or absence of the encoding is switched to enable signal transmission, thereby making it possible to make compatible adaptation to complex laser pulse information and adaptation to high-speed recording.

摘要： In an optical disk apparatus, by obtaining the temperature in the vicinity of a laser in the apparatus, the power source voltage of the laser driver is controlled such that power consumed by the headroom of the laser driver is reduced to the maximum extent without deteriorating the current drive characteristic of the headroom when the temperature becomes higher. The laser driving current of the laser driver is monitored to control the power source of the laser driver such that the power consumed by the headroom is possibly reduced while maintaining the current drive characteristic of the headroom for the monitored current.
