ABSTRACT:
A disc player for playing a first disc having data recorded on both sides thereof and also a second disc having data recorded on only one side thereof has disc drive means loadable with one of the first and second discs selectively. Whether the disc loaded on the drive means is the first disc or the second disc is detected from the data read by pickup means. When the second disc is detected, the pickup means is positioned for the data recording side of the second disc automatically so as to reproduce signals therefrom. Accordingly, even if the second disc is loaded with the disc side oriented erroneously, the data can be read from the recording side at all times.
