Adaptive recording method and apparatus for high-density optical recording apparatus

摘要

An adaptive recording method and apparatus for optimizing power of a laser diode in high density optical recording. The mark size of input NRZI (Non Return to Zero Inversion) data is discriminated and the power of overwrite pulses is varied in accordance with the discriminated mark size, optimizing read power, peak power and bias power for overwrite pulses, to supply optimized pulses to the laser diode.
