Abstract
A method for reproducing an optical recording medium includes: determining a kind of optical pick-up device placed to reproduce an optical recording medium; detecting a push-pull signal or a pre-pit signal of an inserted recording medium according to the kind of optical pick-up device; and reproducing the optical recording medium by using an optical pick-up device from which the push-pull signal or the pre-pit signal is detected.
Claims7
A method for optically reproducing data from an optical recording medium, comprising:
- distinguishing a type of an optical pick-up device;
- determining a manner for distinguishing a type of the optical recording medium according to the distinguished type of the optical pick-up device;
- performing a detection of either a push-pull signal or a pre-pit signal from the optical recording medium according to the determined manner;
- and
- switching the optical pick-up device from the distinguished type of optical pick-up device to another type of optical pick-up device when the detection of the push-pull signal or the pre-pit signal has failed.
