WRITE CONTROL METHOD AND APPARATUS FOR WRITING OPTICAL DISK DATA

摘要

A write control method for writing optical disk data is disclosed wherein pits are written by a write signal composed of mark signal parts and space signal parts, and the length of each pit represents the optical disk data. The method involves converting the mark signal parts to pulses and generating a series of pulse trains which correspond to lengths of the mark signal parts, respectively; controlling the length and/or amplitude of each of the pulse trains in accordance with the length of the space signal part immediately before the mark signal part; and applying successively the controlled pulse trains to a laser irradiation device so that the pits are written.
