Abstract: A defect detector in a data disc system includes a defect estimation unit and a defect length counter. The defect detector inputs a RF signal from a pick-up unit for generating a defect signal. The defect length counter interprets the defect signal using a wobble signal and a header position (ESFS) signal to generate defect length information. A system controller determines which sector of the data disc has unacceptable defect from the defect length information to reassign such a sector to another available sector on the data disc.
