US Patent 7881172 Flexible optical write strategy

A driver includes a parameter generation module configured to generate timing parameters based upon a received bit stream. A timing encoding module is configured to determine a plurality of pulse defining parameters based on the timing parameters. A pulse generation module is configured to determine a plurality of generic pulses based on the plurality of pulse defining parameters. The pulse generation module is configured to combine the plurality of generic pulses into a plurality of enable signals. The pulse generation module is configured to selectively invert a first enable signal of the plurality of enable signals. The pulse generation module is configured to output the plurality of enable signals including the first enable signal to a laser driver.
