发明名称 Write pulse generation for recording on optical media
摘要 The present invention relates to a method and a circuit for write pulse generation for recording on optical media, and to an apparatus for writing to optical recording media using such method. <??>It is an object of the invention to propose a reliable and accurate method for write pulse generation with low hardware complexity. <??>According to the invention, this object is achieved by a method for write pulse generation on the basis of a bit clock, including the steps of: dividing the bit clock by a factor n, multiplying the divided bit clock by a factor n+x or n-x with a phase-locked loop (2, 3) to obtain signal edges which are time-shifted relative to the bit clock, selecting a desired time-shifted signal edge, and multiplying the selected time-shifted signal edge by the factor n with a further phase-locked loop (5, 6) to obtain a time-shifted bit clock. <IMAGE>
