Abstract: Disclosed is a random play control method and apparatus for a disc player. According to the random play control method and apparatus, music information is read out from discs inserted in N (N≧2) disc drives, and then stored. The disc drive subject to random play is selected, and when a plurality of disc drives subject to the random play are selected, music to be first reproduced is determined. Then, a weighted value that determines how long reproduction of the music subject to the random play is continuously performed in the specified disc drive is allocated to the respective disc drive, in a such manner that the weighted value of the disc drive which stores the music selected to be reproduced is greater than the weighted value of the disc drive which does not store the music selected to be reproduced.

Abstract: A method for protecting disc copy of the present invention includes the steps of detecting an identifier of a disc to be reproduced and determining if a disc copy is permitted or not using copy protection disc information and the identifier. A recording and reproducing apparatus having a disc copy-protection function of the present invention includes a reproducing drive for reading data from a disc, a recording drive for writing data on other disc, storage means for storing a copy-protection disc information for judging whether a disc copy is permitted or not, and control means for controlling a disc copy from the disc in the reproducing drive to the other disc in the recording drive.
