Contents copying system, copying method, computer-readable recording medium and disc drive copying contents but not a cipher key via a host computer

Abstract

A content copying system is formed from a host computer and connected disc drive, a removable recording medium being loaded into the latter. When the removable recording medium loaded into the disc drive is DVD-Audio, the disc drive reads a title, recorded on the recording medium and outputs it to the host computer, where it is-stored in a hard disk. When the removable recording medium loaded into the disc drive is DVD-RAM, the disc drive has the host computer read the title recorded in the hard disk, and records this title onto the DVD-RAM. The disc drive does not increment the number of copies made for a title when it is read from DVD-Audio and recorded in the hard disk in the host computer, but only when it is read from the hard disk and recorded onto DVD-RAM.
