摘要： Aspects of the disclosure provide a signal processing circuit. The signal processing circuit includes a processing path and a zero-start module. The processing path is configured to process an electrical signal that is generated in response to reading data on a storage medium. The data includes at least a first field and a second field.

The zero-start module is configured to detect a field change from the first field to the second field, and control the processing path to add a compensation as a function of a profile change from the first profile to the second profile to keep the processed electrical signal to have a predetermined profile in response to the detected field change.

摘要： A system including a demodulator module, a timing module, and a writing module. The demodulator module demodulates a wobble signal having a first period using timing signals having a second period and generates a phase error signal based on the wobble signal. The wobble signal is generated based on wobble information stored on an optical medium. The first period is a first multiple of a channel bit period of the optical medium. The second period is a second multiple of the channel bit period. The timing module generates a clock signal based on the phase error signal. The writing module writes, based on the clock signal, a predetermined number of bits on the optical medium during the first period. The predetermined number of bits written during the first period is based on the second multiple in response to the second multiple being greater than the first multiple.
