Abstract
An apparatus for controlling discrete data in a disk overwrite area or a power calibration area comprises a signal-processing unit, an address-processing unit, a control signal-processing unit, a clock recovery circuit, a signal-processing unit parameter control unit, and a clock recovery circuit parameter control unit, wherein the control signal-processing unit uses a message produced by a data on the disc to determine the control signals such as hold, load, or increasing bandwidth for holding, loading, and increasing the bandwidth of the parameters for processing the related circuits (such as the circuit of the signal-processing unit or the clock recovery circuit) of the discrete data produced between the two data clusters, so as to increase the convergent speed of the circuits for assuring the accuracy of reading data.
