Abstract:
1. An apparatus for controlling discrete data in a disk overwrite area or a power calibration area, comprising: a signal-processing unit, for receiving an analog radio frequency signal and converting said analog radio frequency signal into a digital signal; an address-processing unit, coupled to said signal-processing unit for decoding said digital signal into a sync signal or an address signal of a main data, or taking out a sync signal or an address signal of a wobble signal; a control signal-processing unit, coupled to the address-processing unit for receiving said sync signal or said address signal of said main data, or said wobble signal to issue a hold, a load, or an increasing bandwidth control signal; a signal-processing unit parameter control unit, coupled to said control signal-processing unit for receiving said hold, load, or increasing bandwidth control signal, such that said signal-processing unit executes a parameter for said hold, load, or increasing bandwidth operations, so as to increase the convergent speed of the circuit of said signal-processing unit and assure the accuracy for reading data in a disc; and a clock recovery circuit, coupled to said signal-processing unit.
