Disclosed is optical disc identification apparatus and method. The present invention can identify the kind of optical discs using the different peak-to-peak values of a focus error signal that is produced depending upon the kind of optical disc loaded into the disc drive. That is, the present invention can identify the kind of loaded optical disc using the number and magnitude of peak-to-peak values of a focus error signal detected during a time period when a light source for CDs is turned on and the magnitude of a peak-to-peak value of a focus error signal detected during a time period for which a light source for DVDs is turned on, the number of peak values, and an interval between peak values. Accordingly, the present invention can reduce the time it takes to identify the kind of loaded optical disc, and increase the identification accuracy of the kind of optical disc.
