摘要： An optical disc drive according to the present invention is designed to read data from a multilayer optical disc 100, from/on which data can be read or written using a light beam. The drive includes a light source 222 for emitting a light beam, an objective lens 230 for converging the light beam, a photodetector 236 for detecting the light beam that has been reflected from the disc, and a control section 246 for setting a read power for a particular one of the multiple storage layers of the disc by reference to a read power table 501b. The table 501b stores multiple read powers for the respective storage layers in order to make S-curves of a focus error signal obtained from the respective layers have predetermined amplitudes. In this manner, the optical disc drive of the present invention can be loaded with a multilayer optical disc more smoothly by setting the best read powers for the respective storage layers of the disc.

摘要： An optical disc apparatus according to the present invention includes a disc type recognizing section for determining whether the optical disc loaded is a first type, of which the number of information storage layers is less than a setting T (where T is an integer that is greater than two), or a second type, of which the number of information storage layers is equal to or greater than the setting T. Depending on whether the optical disc loaded has turned out to be the first type or the second type, the apparatus determines the read/write preprocessing (such as whether a fingerprint detection process needs to be performed or not).
