Abstract
Apparatus and method for generating an analog waveform, such as a deflection signal used to deflect a write beam during the writing of data to a rotatable medium having a variable track pitch (TP). In accordance with various embodiments, a first digital to analog converter (DAC) is configured to output a deflection signal having an analog voltage level corresponding to a magnitude of a first multi-bit digital input value applied to the first DAC. A second DAC is configured to supply a rail voltage to the first DAC having an analog voltage level corresponding to a magnitude of a second multi-bit digital input value applied to the second DAC. The deflection signal is used to deflect a write beam supplied by a write beam generator.
