Patent ID: 7807938

Claim:
A system for forming a plurality of cells on a mastering tool, comprising: a laser configured to emit a first laser light pulse having a first power level; a controller operably communicating with the laser configured to generate a first signal having an amplitude that is based on a first amplitude value, the first amplitude value being one of a plurality of amplitude values associated with a first predetermined distribution of position error distances for cells on the mastering tool within a range of position error distances; a light position shifting device operably coupled to a first device, the first device configured to adjust an operational parameter of the light position shifting device in response to the first signal; the controller further configured to generate a second signal having an amplitude that is based on a second amplitude value, the second amplitude value being one of a plurality of amplitude values associated with a second predetermined distribution of cell opening sizes within a range of cell opening sizes for the mastering tool; the light attenuating device configured to attenuate the first laser light pulse to a second power level in response to the second signal; the light position shifting device configured to direct the attenuated first laser light pulse such that the first laser light pulse forms a first cell having a first cell opening size at a first location on the mastering tool, after the operational parameter of the light position shifting device is adjusted in response to the first signal; the laser further configured to emit a second laser light pulse having a third power level; the controller further configured to generate a third signal having an amplitude that is based on a third amplitude value associated with the first predetermined distribution of position error distances for cells on the mastering tool; the first device further configured to adjust the operational parameter of the light position shifting device in response to the third signal; and the controller further configured to generate a fourth signal having an amplitude that is based on a fourth amplitude value associated with the second predetermined distribution of cell opening sizes; the light attenuating device further configured to attenuate the second laser light pulse to a fourth power level in response to the fourth signal; and the light position shifting device further configured to direct the attenuated second laser light pulse such that the second laser light pulse forms a second cell having a second cell opening size at a second location on the mastering tool, after the operational parameter of the light position shifting device is adjusted in response to the third signal.
