摘要 |
A method for monitoring an optical disk drive performance quality by determining a laser diode quality indicator for a laser diode arranged in an optical disk drive for scanning an optical disk, includes measuring an actual value of a parameter associated with a laser diode characteristic, obtaining a reference value of the parameter, comparing the actual value with the reference value for obtaining a comparison result, and determining the laser diode quality indicator from the comparison result. The laser diode quality indicator can at least take a warning level signaling a precursor for a defective state of the optical disk drive and an error level signaling a defective state of the optical disk drive. The laser diode characteristic may be a light-current or a voltage-current relationship. |
