An apparatus comprising a first circuit, a second circuit and a third circuit. The first circuit may be configured to (i) generate a read power signal and (ii) control power of a laser beam emitted from an optical pick-up circuit during a read process. The second circuit may be configured to (i) generate a first write power signal and (ii) control one or more power levels of the laser beam during a write process in response to a second write power signal. The third circuit may be configured to generate the second write power signal and a third write power signal in response to a target write signal.
