ABSTRACT:
The device includes a servo control unit, a data path control unit, a defect detection unit, and a logic combination unit. The data path control unit further includes a preamplifier receiving data from a lens and generating RF signals for data process. The defect detection unit receives the various signals for detecting different kinds of defects to set corresponding defect flag signals. The defect detection unit includes means for ADefect1detection, means for EFMDefect detection, means for RPDefect detection, means for Interruption detection, means for ADefect detection, and means for DSPDefect detection.
