摘要： A method and an apparatus which controls write power of an optical driver by optimizing the number of channels used to drive a laser diode in a write mode while stabilizing the level of a write power voltage at an early stage of the write mode. The method of controlling the write power includes checking whether the write power provided to the laser diode included in the optical driver is stable, controlling the write power by increasing the number of channels used to control the write power so as to provide sufficient write power to drive the laser diode in response to the write power provided to the laser diode being unstable, and controlling the write power by using less channels than the channels used in response to the write power being unstable in response to the write power provided to the laser diode being stable. Accordingly, it is possible to reduce the size of a firmware by preventing channels unnecessary to perform a write mode from being used.

摘要： An apparatus for detecting abnormal states which prevents damage to a laser diode or data recorded on a disc and swiftly correcting the abnormal state. An overflow/underflow detector detects whether overflow or underflow of the laser diode occurs, by comparing a laser diode output power control value, which is output from the laser diode output power control circuit, with an overflow setting value and an underflow setting value. A mode switch switches an operation mode of the laser diode output power control circuit from a recording mode to a reproducing mode, in response to the detection result of the overflow/underflow detector.

摘要： A method of generating write pulse control signals adaptive to various optical recording media, and a recording apparatus adopting the method. In the write pulse control signal generating method, timing data is made with respect to starting and/or ending positions of pulses, relative to rising and falling edges of a mark, wherein the timing data includes a first pulses, a multi-pulse train, a last pulse and a cooling pulse, and the starting and ending positions of the pulses are varied for various optical recording media. The timing data is stored, and then a bias power control signal, an erase power control signal, a peak power control signal and a cooling power control signal are generated in synchronism with an input nonreturn to zero inverted (NRZI) signal, based on the timing data for each optical recording medium. The recording apparatus can store write pulses, which are adaptive to various optical recording media, in the form of timing data, and generate base signals based on the timing data. Also, the write pulse control signals can be generated by the base signals, which controls timing of the write pulses such that the optical recording can be realized adaptive to various optical recording media.
