ABSTRACT:
EFM input signal is received via an EFM input interface. Recording-timing adjustment data is received via a computer interface from a computer and stored in a register. To obtain EFM output signal having its pulse duration controlled on the basis of the EFM input signal and the record-timing adjustment data, there are further provided a clock signal generation circuit for generating clock signal by a phase-locked-loop arrangement based on a crystal oscillator, a first pair of counter and comparator driven by the clock signal to determine the pulse duration of a signal to be written, a second pair of counter and comparator that is driven by the clock signal and responsive to the output from the comparator of the first pair to start counting so as to determine a pulse duration to be adjusted, and a flip flop that is reset by the output from the comparator to provide an EFM output signal having a controlled pulse duration.
