Method and apparatus for discriminating between different types of discs |
摘要 |
A disc discrimination method and apparatus include calculating a first time difference between a time when a first focusing signal is detected from a first recording area of a first disc and a time when a first reflection signal is detected from a first surface area of the first disc, and calculating a second time difference between a time when a second focusing signal is detected from a second recording area of a second disc and a time when a second reflection signal is detected from a second surface area of the second disc. An average value of the first and the second time differences is calculated and the average value obtained as a reference time is determined and a disc type of the first disc or the second disc loaded into the optical disc system is identified using the average value.
