发明名称 WRITE SIGNAL GENERATOR WITH DELAY CALIBRATION
摘要 An aligned write signal generator with alignment calibration utilizes an alignment unit to align a plurality of write signal. The aligned write signal generator includes a write signal generator for receiving an EFM signal and converting the EFM signal into a plurality of write signals according to a write strategy waveform generating rule, an alignment unit for receiving the plurality of write signals, aligning the write signals and outputting phase adjusted write signals, and a phase calibration unit for receiving the phase adjusted write signals, detecting phase error between the phase adjusted write signals, and outputting phase control signals. The alignment unit further receives the phase control signals to adjust the delay time of each write signal.
