摘要： An optical disk recording/reproducing device which records a signal on a disk using a laser beam irradiated from a laser element driven by a pulse signal, wherein an average level detector circuit (70) detects an average level of a monitor signal obtained when a basic pulse signal is applied to the laser element, and an average level of a monitor signal of a reference basic pulse signal is stored as a reference average level in advance in a memory (15). During an actual recording operation, writing in a trial writing region is performed. During the trial writing, a system control circuit (9) compares the presently detected average level to a reference average level stored in the memory (15), and corrects waveform of the basic pulse signal by adjusting a peak level and/or a bottom level of the basic pulse signal to be output such that the detected average level matches the reference average level.

摘要： When setting an optimal laser output, an optimal initial recording output data to be supplied to a laser driving circuit (2) is obtained through a control operation of a laser control circuit. The optimal initial recording output data is then stored. When switching from a reproducing mode to a recording mode, the optimal initial recording output data designated through the setting of the optimal laser output is supplied to the laser driving circuit (2) while feedback control is prohibited. In this way, recording can begin immediately after switching from the reproducing mode to the recording mode.

摘要： When a record decision unit 22 judges that recording has been interrupted, the recording data in a predetermined frame is ended. Data are continuously recorded onto a disk until the frame synchronous signal duration following the predetermined frame. Thereafter, the control output generated from the head output controller 14 is controlled to interrupt the recording operation. When the record decision unit 22 judges the resuming of recording, the control output from the head output controller 14 is controlled to resume the recording operation onto the disk from the frame synchronous signal duration in which the recording of data onto the disk has been interrupted.

摘要： An optical pickup configured so as to reproduce signals recorded in optical disks of plural standards by means of a single laser beam. The optical pickup has an objective lens (5) for gathering a laser beam emitted from a semiconductor laser (1) - which emits a laser beam of single wavelength - onto a signal recording layer provided in each of optical disks of first (D1) and second (D2) standards whose cover layers differ from each other in terms of a thicknesses. The first standard is; for example, a CD, and the second standard is; for example, a DVD. An optical path length correction member (6) - in which there is formed an optical path length correction section for making a correction to an optical path length falling within a range smaller than the diameter of a light beam passing through the objective lens - is provided in an optical path between the semiconductor laser and the objective lens. The optical path length correction section may also be formed on a lens plane of the objective lens facing the semiconductor laser.
